Leaves as sleepingbags

Recently Jess heard about a technique for sleeping out in cold weather where you use trashbags filled with leaves as insulation. This sounded pretty cool, so we decided to give it a try. In addition, we wanted to cover a little bit of ground, just because neither of us had done a longer-distance backpacking trip in a while.

I'd also been playing with the idea of doing trips without a cookpot, by cooking sausages over the fire as warm food. If you've been reading this blog you know we've also been trying ponchos as shelter, so there's no separate tarp. Well with no sleepingbag, no cooking gear, and no tarp, that's the bulk of the gear, so we were pretty excited about this itea.

We weren't sure exactly how it would work, so we brought both emergency bivies (I actually had 2 as I had one that had already been used), and contractor trash bags. We also had sleeping-bags and extra coats as backup. Despite actually needing so little, with all the backup gear our packs still came out looking about normal. You'll see at the bottom though that the gear-list is a bit odd.


Selecting a site

We walked in a pretty long way. At some point we were talking about tea and I realized that I'd forgotten it. So we stopped to get some tea fixings. Fir is usually pretty good.


A while later we found a nice spot next to a stream. When using possibly marginal setups site selection is really important. We ended up on the south-facing part of a west-facing slope quite near a stream. This surprised us a lot actually. As a rule you want a south-facing part of an east-facing slope and you want to be relatively far from water so the humidity is lower. But, the spot we ended up in was quite sheltered and felt easily a solid 5-10 degrees warmer than the general average at the time. The stream didn't matter as it was steep enough that the damp air could fall down the slope and didn't build up near our campsite. All in all it was a pretty perfect spot.

After some discussion we decided that we were concerned about wind only from one side, so the smart thing would be to sleep on the lee-ward side of a log, in case the wind came up that way. Having finally selected our site we started building.

Making the beds

Our first task was to build insulating matts to sleep on. After a bit of consideration we decided to start by building platforms out of branches, this would supply us a solid separation from the ground even before adding leaves as padding and insulation. This is when we were about half complete.The near bed is mine, the far bed is Jess'.


As you can see my technique isn't working quite as well as hers, I switched to something half-way in between her technique and mine after this photo. We also both placed branches as "rails" that sat higher on the sides and ends to help hold the leaves in.

Next we gathered leaves... lots and lots of leaves. We heaped these on to the beds until the beds were mounded high. Then we'd lie down on them squashing it all down and repeat. I found it helpful to gather into one of the contractor bags I had brought actually, as a way to gather from the best areas. Sadly, I didn't take any photos of this stage.

Once we had our beds we started on our sleeping-bags. Jess and I had slightly different ideas for this. I have tried sleeping in an emergency bivy several times, e.g. http://www.blog.smalladventures.net/2013/08/bushcraft-in-lassen-national-parkforest.html, and every time I do it I end up waking up soaking wet. To make it work I have found that I have to wait until I can't stand it anymore and *have* to use the bivy, to minimize my time in it. Otherwise I'm so soaked by the low around 4-6 am that I end up really chilled. This happens basically no matter how cold I am. Jess doesn't have this problem, she generally sweats very little while sleeping unless she is overheated.

As a result, Jess decided to use an emergency bivy, fill it with leaves, and then climb in to it with a silk liner. I decided instead to use my bivy like a quilt. I flipped it inside out (so the shiny part is out), filled it with leaves, swashed it flat, tied one end off, and used it like a quilt. Here's the bivies filled with leaves.



Next, we pitched our poncho/tarps. The weather here has been very unpredictible lately and there was a predicted chance of rain, it kept shifting. We decided we really didn't want to get wet, and that the tarps might help a little with heat. This turned out to be the single hardest tarp pitch either of us had ever done, due to having to precisely locate the tarps over the beds. As a note, I find I need 50ft of twine (that I never cut) for a normal tarp, but I prefer to have more for a poncho-tarp. We intentionally hadn't brought stakes, but with a few carved stakes and some ingenuity we got it up and had a nice shelter.



The leaves were so dry that I used them as tinder. I struck a spark off a faro-rod into a bit of cotton from the top of a pill bottle and that lit the leaves. Within minutes we had a nice roaring fire. Next we gathered wood and bucked it up using my handsaw.


The sunset was spectacular. We dined on sausages roasted on sticks jammed in the ground, and some bread we'd brought with us.

How did it work?

We were both pretty surprised at how warm our setups were. We figure based on feel an local weather reports that it was maybe ~40F that night. Jess' was definitely warmer, as she had no air-gaps she said she was actually almost too warm, and that her setup would've worked down to much colder temps.

My quilt setup worked pretty well, but not perfectly. The emergency bivies are really too narrow to use like a quilt, because they don't droop over the sides enough to seal in the air. That said, throughout the night I slowly sank in to my leave bed, so the leaves around me started to seal the gaps from below. I could also snuggle up to the log a little letting me seal one side and in effect gain some width. Overall it worked just fine, and I would've been comfortable 10 or 15 degrees cooler easy, it's hard to say if it would work colder than that though, as it's a very odd feel. Some of the leaves are damp, and the mylar was against me, so it felt colder than it was.

One big advantage of the quilt method is that you only need ~4-5" of loose leaves. shoved in to the bag, more and it makes it stiffer and harder to use. With the sleepingbag method the leaves get crushed down easilly, and you need them to be densely packed enough to keep some on top of you. As a result, Jess found she needed several times more leaves than I did, making the setup take quite a bit longer.

Overall, given my sweating, the next time I try this I intend to use the quilt setup again, but with a bag that's maybe twice the width of the emergency bivy.

The rest of our trip

In any case, we both slept in comfort and woke up refreshed in the morning. After getting up we cooked up some sausages on our still going fire (I'd gotten up and tended it 3 times in the night). Once again I was reminded of how much longer large slightly damp logs burn than small dry ones do.


The next day we had a long beautiful and slightly more round-about hike home. Beau had a blast the whole trip, with her winter fur she was completely content the whole time.



Here's the gear I brought and expected to use. Note that this is absolutely everything... I took this photo after I got home, and stripped naked to take it :P.

This is the stuff that I brought as backup and didn't use (actually, the gators were brought as another experiment, but it didn't end up raining on us).


  • canvas pants
  • wool sweater
  • canvas shirt
  • warm boots
  • wool socks

  • belt knife
  • wood saw
  • steel water bottle
  • steel thermos
  • emergency bivy x2
  • contractor bag (only used to speed gathering)
  • poncho w/ 100ft twine
  • backpack w/ drysack
  • ursack w/ food
  • Warm rabbitfur hat
  • warm work gloves
  • sparker
  • tinder (cotton)
  • bandanna 
  • personal drugs (for medical condition)
Unused (planned as backup):

  • wool jacket
  • down sleepingbag w/ drysack
  • gators (intended to test in the rain)
  • contractor bag
Unused (would normally bring):

  • scarf
  • tights
  • med kit (pills)

  • headlamp (battery was basically dead)
  • sighting compass
  • lighter
  • fatwood
  • homemade hacksaw-blade backup knife
  • backup personal drugs (for medical condition)


Overall it worked! Jess' technique worked well for her, and mine worked well for me.

In really cold weather if I'm worried I think I would go with the "sleeping-bag" model. If it's cold enough than the Mylar bag won't make enough difference and the temperature at the Mylar bag will be below freezing. In this case the sweat will condense there and then freeze solid, thus keeping you dry. I would also recommend this method in other weather for folks who don't sweat much. Note though that this technique is trickier to get in and out of.

In warmer weather I think I want a bag that is twice as wide as a normal emergency bivy. This would be much faster to stuff with leaves than the sleeping-bag approach (despite being larger the leaves can be fairly loose), is very easy to adjust for temperature, and is super easy to get in and out of. This seems to me like the more general approach that I'd like to understand better and persue, as it should work in fairly cold weather as well.

Note that this technique only works when there are fluffy dry'ish leaves about. If we had a bought of freezing rain that soaked everything and then glued it to the ground, the leaves won't be very insulating. It remains to be seen what weather allows one to still get good enough leaves.

That said, in VA I suspect this technique works quite a bit of the time. It's especially tempting to adjust gear for day-hiking a little to allow for doing this, as it would allow one to voluntarily or not, actually have a fairly comfortable night in a fairly wide range of circumstances, while likely adding almost no weight to your normal kit (since many of us already carry the necessary components).

The sleepingbag for me has proven to be one of the hardest pieces of gear to substitute for or drop so far. So, I'm really excited about the possibilities this opens up and I'm really curious to see just how wide a range of weather I can get it to handle. I'm toying with the idea of making a bag for this purpose, maybe something like a "survival scarf": https://www.youtube.com/watch?v=LElsE3kseQM. Given that and a poncho I could sleep out in a lot of different weather while carrying a very very small pack. Also, it's one more step towards dropping plastics out of my kit.


Jeep plans (lift, gears, and lockers)

I've got this Jeep, and it's pretty cool. But, I want to make it cooler.
My plan from the start has been to build a not-flashy daily-driver with a moderate lift, that performs well on road and better than it looks like it should on the trail. Because it's a neat challenge.

To that end, I've been looking in to:
  • Lifts
  • Gear ratios
  • Transfer cases
  • Lockers
  • Armor
I actually just bought all the stuff for the lift. The rest of this is looking off into the future should I decide to do it. I wanted to understand everything I *might* do, to make sure I didn't do anything incompatible with it, just like designing a complex distributed computer system at a high-level, even if you're not sure if you'll actually implement some of the fancier features.

I should note that this represents a fair bit of research on my part. I'm only just learning about all of this. I've done one lift in the past, and it was quite a simple affair on a coil-over front and leaf-spring rear, and it came as a boxed as a kit. Once I threw out that option, I got in to building up my own kit from individual parts, which gets complex fast.

I don't know what I'm doing... this is just what I found. I'm happy to take suggestions, input, or questions.

Lets start by talking about lifts. I'm running 33" duratraks, which so far I like a lot. They have great on-road manners. I was playing in the mud a little last weekend and they performed great. We were on hard-pack, slime, and hitting mudpuddles. I'm running 33" because they are the largest tire you can easily run without damaging components, they also happen to be the largest tire that runs well with an unlifted Jeep... convenient. My stock height was 8.7" ground clearance, going from 29" to 33" tires I got another ~1.75 inches (tires aren't exactly the size they say), so now I have ~10.0" of clearance.

My Jeep is solid axle front and rear, with coil springs and independent shocks. Getting lift is easy, you swap out the springs for taller (and/or stiffer) springs. BUT if you lift a Jeep JK more than about 2.5" things start getting harry. Your steering geometry gets all mucked up and you end up swapping out half of the parts under your car.

What I think I want to do is to raise the vehicle another 2", so I get 12" total. At this point it's a matter of finding a set of springs that do that. I could do spacers instead (just blocks that sit on the coils), but I don't want to for reasons I'll explain shortly.

It turns out finding springs that will raise your vehicle 2" is a lot harder than it sounds though. A 2" lift maybe built for a heavier version of the Jeep, in which case it could lift it as much as 5", even if it's built for this model they are usually designed to get that lift over stock height, after also adding heavy bumpers and such. I plan to keep my Jeep quite light, so a 2" lift is likely to be at least a 3" lift. After a lot a lot of looking at various springs on the market, I don't like almost any of them. Most of the "triple rate" springs are a sham, and are also too short (I explain why this is bad later), and most of the good springs give 3" or more lift.

All of this is even further complicated by JKs having all different springs from the factory. While what springs they have is vaguely correlated with the model, it's only very vague and almost any spring will occasionally be found on almost any model. This means if you look at the current ride height that's based on some unknown quantity.

Luckily you can go look, I have 13's in front and 55's in the rear. As it happens this means I could get ~1.75" of lift in the front and maybe 1.5" in the rear by buying stock 19/60 springs someone else is swapping out. As it turned out I couldn't find these, so I got 18/59, we'll see how much lift I get out of it.

Now, the lift isn't just about getting the vehicle higher, it's also to increase droop, that is, the amount the axle can travel downward from it's normal position. I'd like to increase droop as much as is reasonable.
Droop lets you articulate more, meaning lets the axle pitch relative to the body of the vehicle more. The more you can articulate, the easier it is to keep your wheels on the ground in harry situations, surprisingly, more articulation also helps with stability and avoiding rolling the vehicle.

So, how do we get droop? The first limit to droop is usually your shock, which has a limited throw. If your axle is just hanging from the car, that's what it should hang by. So, to increase droop you want to swap out for a shock with a longer throw. The complication is that this usually also increases the minimum length of the shock as well. When the suspension is all of the way compressed, if you sit on the shock, you generally destroy the shock.


A good shock absorber will actually make my car much safer and better behaved on the road, as well as off the road. Right now when I corner hard the rear wheels frequently leave the pavement causing the car to oversteer. I don't like this, and better shocks should help.

After much research it turns out the Bilstein-5100 just barely fits on my vehicle with no modification, it has a significantly longer throw (4 inches in the rear, 2 in the front), and it's minimum length is only just smaller than my minimum length. As a bonus I had Bilstein 5100s on my last car, and I loved them, so I'm happy to use them again.

Oookay, but is that actually what we want, is it possible to let my no 33" wheel go ALL up without something else bad happening? To answer this I used a rock next to my driveway:


Below you can see that it's close, but at full stuff, my rear tire clears by maybe an inch and a half. This axle is sitting on it's bump-stop. I'll have to watch that if I ever run aired down though, since that can bulge a tire out a bit. This is with the current sway-bar, which I intend to leave.


And up front we see again that it clears fine. I'm actually about 2 inches from full stuff, but there's plenty of space. That's a good thing, because up-front I may decide to disconnect my sway-bar at some point, which would let it articulate further.


Now, if you think through the geometry. If the far wheel is drooping another 4 inches, this side is going to come up yet another inch (thus why the sway-bar matters). It might just barely clear, it might not... that'll be something to test. If it hits I'll probably rig some tiny spacer for the bumpstop, any bit of rubber will work. It's definitely in the ballpark, which is good enough for selecting parts.

So, it looks like we can use most of the uptravel. I don't want to get in to welding my frame and crazy stuff, so bilstein 5100 should work perfectly, getting me the maximum droop I can get without crazy modifications.

You have to extend brake lines and a few other things, at some point on the 2015 Jeep JK, it turns out the driveshaft hits the exhaust, and there's a couple of other issues. These can be surpassed though with a little work as they arise. Another example is the sway bar links, which I'll want to extend. If you don't extend them it turns out they can invert, and break things. Still, I don't know how long they actually need to be, so I figured I'd see it all in place first and measure. There's also disconnectable sway-bar links which give more articulation make the vehicle less stable offroad, but keep full stability on road.
I'll probably keep the non-disconnects for now, since as it happens I can likely replace the rears and move the rears to the fronts... I can also probably hack up a disconnect myself.

More about coils
Besides those things, the next thing to limit your droop is your spring length. At some point the axle droops enough that the coil just falls out. Oops! For this reason you want a nice long coil. When the suspension compresses though the coil can be the limiting factor on that end, so you want one without too many turns. Spacers just take up space that could be used by coils that will unfurl, so spacers are bad for your droop if coils are your limiting factor. For this reason, I want a pure coil suspension if I can get it. As it turns out, not many aftermarket coils in the 1-2" range are longer than the longest stock ones, so that's another advantage of going with take-off OE springs.

Gear ratios

A 4wd car has an engine, which drives the transmission, which drives a transfer case, which drives the differentials, which spin the axles, which are connected to the wheels. The final gear ratio between the engine and the wheels depends on the product of the gear ratios at each stage.

My transmission has 6 gears, and my transfer case has 2. The transfer case is also responsible for swapping from 2 to 4wd (engaging the front wheels or not). Usually the high gear of the transfer case is used for normal driving, and you just use the transmission to shift. You can swap to 4wd still in the high range, and drive like normal on slick roads. When you need lower gears for crawling up steep hills really slowly you swap the transfer case to low range, giving you a whole new range of gears to shift between on the transmission.

Now, my car had ~29" tires and now has ~33" tires. This affectively changed the gear ratio of the whole drivetrain by ~10%. This is okay, but if it gets to far outside a reasonable range, 6'th gear becomes useless, and it gets hard to get up hills in 1'st. Usually people compensate for this change in the differentials. My car came stock with 3.21 gears in the differentials. The JK is also available with 3.73 and 4.10 gears in the diffs.

Interestingly, the differential gearing, transfer case, and transmission, are all the same on JKs prior to 2012, but at that time they were mated to a significantly less powerful engine. Personally, I actually think the feel of my car on the street was *improved* by the whole thing being shifted up a little. Most Jeep people would call me crazy for saying that, but hey, I'm used to an underpowered Toyota on oversized tires. Anyway, all of this is to say that I want to keep my gear ratio in the differential (I think).

But, what about when I 4-wheel? When I'm wheeling I'd really like that torque back that I lost by increasing the tire size. Well, if I like it when the transfer case is in high (which, btw, is 1:1 in the transfer case), and I don't like it in low (1:2.73 I think?) then maybe the answer is to change the transfer case!

Transfer case

I'm not doing this any time soon, but I want to figure out every change that I think I might want to make eventually, so I can make sure they all work together well. As it turns out, there are some very nice transfer case swaps available that make for a much lower low range (higher gear ratio numerically). After doing a bunch of research, if I did this I'd probably install a 4-speed transfer case from Atlas. This gives you 24 gear ratios, instead of just 12. The advantage would be having good gears for climbing hills and the like, as well as super super low gears for slowly crawling over dangerous stuff. It's not that I care about torque, actually the torque is bad since it breaks components. But going slower makes it easier to not break things, and that I like.

Differentials are designed so that when you spin the input shaft, the output shafts spin. If you hold one output shaft, the other spins at double the speed. This allows cars to go around corners. A locking differential allows you to disable this feature and make both wheels turn at the same speed, this way if one wheel is off the ground, the one on the ground is still forced to turn.

My first Tacoma had a locking rear differential, and I *loved* it. Having a locking differential doesn't matter much most of the time though. I discovered with Jane (my last Tacoma) that after I lifted her, thus giving her more articulation so she could keep her tires on the ground, I didn't ever need lockers the whole time I was mucking about in California.

The exceptions though are snow, mud, and ice. California had very little of any of these, but as soon as I hit snow in Jane I wanted one again. In these cases having your tires on the ground doesn't guarantee that you have traction, so the locker is still useful.

So, I want to install locking differentials eventually. This ties in to the decision about what gear ratios I want in the differentials, since if I replace/rebuild my current differentials and add lockers, I'd like to do the whole thing at the same time.

My current plan is not to armor my vehicle at all. I like it being light, and I like my gas-milage. My hope is that with the lift I'll get enough clearance that I don't have to worry about it. If I armored up much I would definitely have to change my axle ratio to 3.73 for normal driving, and it's possible that will happen, but for now I'm going to try not to. If I did armor up, it would probably be to add rock-sliders to protect the quarter panels (the painted bit below the door, between the front and rear wheels). Some rubicon stock sliders would be about perfect if I do decide that I need them, and still keep things light. 


Winter overnight

Last weekend I had a free evening, so I grabbed my pack and lit out. I didn't go very far at all, maybe 2 or 3 miles in from a trailhead near my house. I was taking care of Jess' dog at the time, so she came to.

This was the perfect time to test some things and just muck around. I recently bought an Opinel folding saw, which I picked it up from the mailbox on my way out. I also grabbed my little Gransfors forest axe, and my new bush knife that I bought from the maker at a gathering.

Cutting implements

This is a lot of cutting tools to carry, but I thought I'd bring them all and play around, to see how each fared at normal camp tasks. I actually also have a true Nepalese Kukri, but I didn't bring that on this trip.


I usually carry your typical Mora knife. They are great knives, very easy to sharpen being Scandinavian grind, etc. But, while you can baton with them (hit them with a stick), the blade is a little bit thin for it. I got this bush knife with the idea that it could do heavier tasks more safely than the Mora is capable of... so, it starts encroaching on Axe territory. It's a great knife, and feels really nice when whittling and the like, but I haven't had it long enough to have a well informed opinion yet, but it's looking good.

The Opinel folding saw was a new idea. Since it's winter here I've been reading and watching videos of people who do bushcraft in the Alps. One thing I noticed is that these folks often carry folding saws. Watching them and thinking about it I realized that almost everything you do in the winter involves cutting sticks, usually in the 2-3" diameter range. Being able to cut sticks cleanly to specific lengths makes things easier, building a quick shelter, building a stand for your fire, cutting really short pieces of wood for a small fast fire, instead of having to burn the pieces in half, etc. You can always cut sticks with rocks but the rocks may be buried under a bunch of snow making that less effective. You can break sticks for sure, but it just makes some things harder, and winter is challenging enough for me right now. So, I decided to give a saw a try.

Overall, I am REALLY impressed. This is an amazing saw. A saw is really the right tool to be using when bucking up your normal deadfall firewood, much better for that than an axe. As a result it was significantly faster than the Axe.


I cut about 2 armloads of wood with it, so I could keep the fire going most of the night (more on that later).

Axes and machetes and the like are quite heavy and bulky to carry. This saw is much lighter. It's just a little to big to stow in a cargo pants pocket.

If I was building shelters, I would prefer to have *both* though. If you take a small, say 18ft dead pine tree and lop off all the branches until you just have the trunk, a machete is by far the best tool for the job. Next best is an axe which is a bit slower, but compared to my machete doesn't wear out my pinky finger as badly. The saw would be a pretty distance 3'rd in that category. Given the choice of either the saw or the axe for shelter building, I think it depends on the forest I was in, but I'd probably pick the axe.

After I had a fire lit and was just hanging around I decided to make a spoon, because why not make a spoon right? The first step was to split a stick (if you're paying attention you'll note this spoon is not going to work very well). I could do this with an axe, but it's extremely gross. A knife, hit on the back with a stick, is an extremely accurate tool for splitting small branches. I then whittled this into the beginnings of a spoon shape to get comfortable with how I wanted it to come out.


Next I cut a green stick and split that, again using the knife (this step would be much much harder to do safely with an axe). I bent the stick over to make a set of tongs


Then using these tongs I fished a coal out of my fire, placed it on the spoon and blew on it. After it got nice and chared I'd scrape the char out with a rock, and repeat. This is the process used to make what's often called a "burn bowl", this is a burn spoon I guess.


After a few iterations of this, with a little care to how you place the coals, you get a nice bowl shape


I carved it a bit more until it was sufficiently spoony that I could've used it... but there's a key flaw in this spoon which should've been obvious initially. It includes the very center of the wood, which almost always checks badly (meaning it splits while it's drying). As a result this spoon is already splitting badly, and will fail very soon, so I gave it to the dog to shred instead of saving it. Oh well, it was good practice.


To get the fire lit I first tried out a method I saw a video of someone in Switzerland using. It just made a lot of sense. It's called the "3 stick method". Well... it requires sticking the 3 sticks in the... snow... err... yeah, suffice to say that it didn't work in ground that was frozen solid. One more learning experience!

I had carried in a few bags of tea with me, since we have so few evergreens here, and I knew it would be cold. I also had 2 stainless steel water bottles (kleen kanteen brand). One is a 1 liter bottle, the other is a 1 pint thermos. This was great, as I could boil stream water in the 1 bottle, then transfer it to the thermos and sip tea while I was working on my spoon and whatever else.


Then I cooked dinner on the fire, and just hung out. When I left home it was ~15F and I believe it dropped to maybe 5F that night, so it was pretty chilly. Beau didn't care at all though, she was running in and out of the water until this happened:


It'as a bit hard to see, but she has balls of ice on her fur all up her legs and across her belly, almost 1/4" across. She picked them out slowly, and didn't really mind much.

I was also experimenting with clothing. I decided to minimize my use of modern tech and was wearing a wool 260 weight ice-breaker sweater as a base layer, a 5.11 canvas shirt over that, with a thick wool jacket over that. My hat was wool. I had on underarmor running tights (I don't own wool tights, something I'd like to fix someday), and 5.11 canvas pants. Wool socks, and fancy modern waterproof hiking boots, lightly insulated. On my hands I had wool liner gloves and thinsulate lined 2 layer gortex mittens. In reality I would've been fine without the mittens... now I know!

Interestingly, even sitting around at 10F or so this was plenty of clothing. I was quite comfortable, especially sitting on a closed cell foam pad, and drinking hot tea. Very pleasent :D.

I carried in an extra pad for Beau, as I was worried about her getting cold at night.


She was definitely thankful and slept on it the whole night. Unlike this picture I had it folded in half so she'd get 2 layers of insulation.

While she was sleeping on an my old beat up one (this pad has done 1500 miles on the AT, 240 on the JMT, was my bed all last summer, and has been on countless other trips), I was sleeping on my much newer pad, otherwise identical. I also made a pile of of leaves to try and get some more insulationg, knowing just the 3/8" pad (even from gossamer gear, which are better than most) wouldn't quite cut it.

Well, the dog was just fine that night, she curled in a ball and slept great. I checked her ears and paws occasionally, and they were always warm, I never once saw her shiver.

Me on the other hand, I was cold... especially when I got nervous enough to bring the dog in my bag for a few minutes to let her warm up (which was totally unnecessary). My 5 degree quilt is well used and isn't really 5 degrees anymore. It also has a hole in the bottom of the foot that I usually plug with my down vest, which I hadn't brought. I was using the quilt and my ultralight MLD bivy, another piece of gear I've been experimenting with more lately. I was in no danger by any means, I just wasn't as snug and warm as I had expected to be.

I managed to keep the fire going for much of the night... except the coldest part of course. Oh well. I also melted a small hole in my bivy and sleepingbag. This would upset me more if the bag was new, or the bivy was waterproof, but I do need to do some patching. It turns out you can't use a down bag AND warm up by a fire. I knew this, but tried it anyway. I had build the fire in a pre-existing fire-ring that raised it up somewhat above the ground, this made banking it nigh impossible, especially combined with the ground being frozen solid. The wood there is a very fast-growing oak that burns almost like a softwood. So, that's why I failed to keep the fire going.

The next morning the dog had ludicrous amounts of energy and was so manic she was playing tug-aware with the backpack after I got it on her... it looked just as hilarious as it sounds, sadly I didn't get photos. I got enough sleep to be pretty happy, and had a nice pleasant walk out.

So, lessons learned:

  • A good folding saw is an amazing tool, and I'll probably bring one on future winter bushcraft trips.
  • To make a spoon, find an unchecked stick, or split a larger stick and use it off center
  • The 3 stick method doesn't work without a soft substrate
  • A stainless steel thermos and bottle is a wonderful combination of water bottles for winter trips
  • Beau basically doesn't get cold, I won't worry about her again unless it's well below 0F
  • Wool and cotton/nylon canvas blend layers are entirely reasonable for winter backpacking
  • For colder weather, I could really use a warmer bag, and maybe a warmer sleeping pad

And... best of all, I got to spend a nice 20 hours or so outside instead of inside. It was beautiful both days. It feels so good to wake up in the forest, and have the first thing you do be to pack up your stuff and start walking.
