Hammock Bunk Beds

It's been a while since I have blogged. The reason is because I haven't been able to backpack recently. I had a big trip planned for the second week of March that ended up not happening. It was Spring Break at the University but not at my kids' schools. So I decided to try a 3-day trip on one of the longer sections of the Ozark Trail. I bought my food, packed up my gear, printed my maps, and had it all ready to go the night before. The next morning I woke up with a stomach virus including vomiting, fever, body aches, the works. So no backpacking trip.

Since then my teaching load at the University has increased and so there hasn't really been time to get away.

I have a new piece of gear I've been wanting to try but so far have only tried in the back yard. It's an 11x10 Cat Tarp from Jacks R Better. The Cat stands for catenary, meaning that the sides are cut as catenary curves rather than lines. This means that the tarp flaps less in the wind. The large size means that there is enough excess room that you can fold the edges of the tarp in to create doors as I did below.

This provides extra protection from wind and rain. Notice that I have also pulled out the sides to make it look even more tent-like. There is one tie-out on the side of the tarp in the middle but I created a second one using Grip Clips. You can see what I did more easily from the side.



I could have put doors on both sides but that begins to defeat the purpose of a tarp which is to provide maximum ventilation (to prevent condensation). Also there was really no room in this case because I set the tarp up along the short axis to make it as tall as possible. The reason was that Debbie and I were going to test the tarp out together in two hammocks, bunk bed style!

Here was the setup. I put the bridge hammock on the bottom and a simple gathered-end hammock on top.

And here's our lovely model demonstrating!


The weather was a bit cold, about 40 degrees with wind, so we each used a closed-cell foam pad under us. I followed the advice of a friend on hammmockforums.net who suggested putting the end with the doors into the wind. That way the tarp splits the wind rather than providing a big target for the wind to push against as it would be if you faced the broad side of the tarp into the wind. The open end faces away from the wind. Stopping the wind this way is critical when using a hammock because the wind will carry the warm air under you away and you will feel chilled.

This setup worked wonderfully. Debbie and I were amazed at how comfortable we were and we went right to sleep. It's nice to have your spouse close to you when you are camping! It make it feel so much more natural to go to sleep, even in the outdoors.

Interests Relating to Backpacking

I've found that backpacking has sparked my interest in several areas that I hadn't really thought about much before. I'm finding myself googling things more often to learn the answers to questions that come up during a hike. Backpacking puts you more in touch with the natural world that we usually don't see or think about.

Forestry

Trees are the first thing you begin to wonder about in the forest. You feel stupid not knowing what these trees around you are. After I'd been on a few hikes I began to wonder what kind of trees I was seeing and what were the nuts I kept finding on the ground so I began asking questions. Now I can recognize a Hickory nut and I know which tree it comes from. I never knew what Hickory trees were before. Now I'm wondering if it's Hickory trees that give the Ozarks their particular smell. The smell is subtle but quite nice. The other day I took out one of my tarps and had the family smell it compared with the smell of a brand new tarp that I'd never used. "That's the smell of the Ozarks" I told them. However I don't know yet that it is Hickory that I'm smelling.

I always knew what an Oak tree was but after reading Allison Vaughn's recent blog entry I'm anxious to get back and see if I can tell which of the oaks I'm seeing are post oaks and which are the red or black oaks. Apparently the post oak is adapted to the fires that once were common in the forest. Now that we stop forest fires the red and black oaks (that can't tolerate fire) are taking over.

Astronomy/Star Gazing

Last Thursday night on top of Taum Sauk Hyrum and I were struck with the perfect view we had of the stars. We were on top of the highest mountain in the state, far from any major town, with no leaves on the trees and no clouds in the sky. As I looked around I found that I wished I knew more about the stars I was seeing. I could recognize Orion's belt but that's about all. Here's a picture I stole from the web somewhere. You can see the stars that make the belt. I figured the two bright stars underneath must be his feet and the two upper ones were his hands. A very rough approximation of a person I thought. I started reading about the constellations and found that Orion is the big winter constellation. After spring it falls below the horizon. I also learned that there is more detail in the constellation than I originally thought.

You see that bright area just below the belt? That is often called the sword. Now look to the right of the upper stars. There are 4 smaller stars in a semi-circle. That is the bow that Orion is shooting.

The stars in Orion are among the brightest in the sky. Including Rigel (bottom right) and Betelgeuse (top left). The sword is actually not a star, it's the Orion Nebula.

Pretty cool. I'll have to study up to see what other constellations there are to see and how they change with the seasons.

Entomology

We all see bugs from time to time but we mostly step on them, shoo them away, or ignore them. In the woods I see some pretty cool bugs sometimes. This fall while on Bell Mountain I stopped to cook lunch and when I finished and turned around to get my pack I met this fellow.
It's hard to get the scale from the picture but he was about 5 inches long. Learning names of insects is much harder than birds or animals because there are so many. But the variety itself is pretty incredible. I never really cared before but while hiking I have time to look at these things and now I'm wishing I knew more about them.

Geology

All kids are interested in rocks as a rule. Very few adults are. But once again the fact that you have more time while backpacking makes all the difference. Here's me picking up a rock while hiking with my brother near Council Bluff lake. You can't see the rock very well. It looked almost like a geode to me but not quite. These things were everywhere.

This winter I returned to this same general area to hike the Middle Fork section. The northern end of that trail is near Council Bluff. Here's a larger stone of the same kind. I just had to stop and look at it and take this picture. What in the world is going on here? It's softer than a geode. It seems to be made of sand but why these bumps instead of flat layers like most sedimentary rocks?


Hmmm. Still got a lot to learn.

Mina Sauk Falls

With Saturday being Valentine's day I knew I couldn't do a weekend backpacking trip. But Hyrum had Friday off from school and I didn't have a class to teach or a seminar to attend so we headed off to spend Thursday night on a mountain.

Missouri is not the land of high mountains. In fact you can drive right to the top of Taum Sauk mountain, the highest mountain in Missouri, and look at this plaque. There is a campground near this spot where we spent the night.

Here is Hyrum enjoying a brief moment as the highest person in Missouri. (Actually he was the highest person in a several state region since there is nothing higher in Iowa, Illinois, Indiana, or Ohio.)

In a previous post I described hiking the trail that leads to the top from the Ketcherside trailhead. During that trip we hiked down to Mina Sauk falls, the highest waterfall in Missouri (132 foot drop in total) but I forgot my camera back at camp and so got no pictures. It didn't matter much because on that occasion there was no water. The falls only run after wet weather. We got quite a bit of rain on Wednesday so I thought we might get a nice view on Friday morning. We weren't disappointed.

The side of Taum Sauk where the falls are located (a little over a mile hike from the peak) is very rocky. The creek cascades down a rocky cliff but not in a straight line so there is no way to get a view of the entire falls without a helicopter. No picture from the ground really does them justice. Here is a shot from quite a ways back. But you can really only see the middle part very well. At the top of the picture you can catch a glimpse of the uppermost part of the fall.

Standing at the top this is the view you have looking down.

There are two trails from the peak to the falls and we took one going down and another coming back. The entire loop is just under 3 miles.

All in all we had a great time. Hyrum is a natural camper. Once his head hits that hammock he is asleep and doesn't stir til morning. Even with a comfortable hammmock and a quiet night (like we have in the winter) it's not that easy for me. I have to lie for quite a while before I can convince my body that it's okay to fall asleep even if I'm not in my bed at home. One of the difficulties of age I guess.

Tent Stakes

The weather lately has been very interesting. Just a few days ago the highs were in the teens. Today it was near 70 degrees. There's Missouri for you. The nice weather makes me anxious to get out on the trail but there's still a lot of snow on the trails (now a lot of slush) which makes for unpleasant hiking. So instead of reporting on a trip I'm going to talk about gear again.

I mentioned in a previous post that I was having trouble with my Tite-Lite stakes. In general I like these stakes a lot. They are very lightweight and work great for pot supports for cooking (as I described in this post). The problem is in the winter when the ground is frozen. I've bent a stake trying to get it into the ground.

I've also lost a stake when the wind caught my tarp and ripped the stake out of the ground, sending the stake flying to who knows where. So I purchased some 8" Easton Aluminum stakes. These stakes are surprisingly light and strong. You can pound on them without worrying about them bending. Also, rather than a shepherd's hook at the end they have a cord which you can tie to your guy lines. That means that even if the wind rips the stake out of the ground it will stay attached to your tarp and not get lost.


I set up my tarp in the back yard and slept under it during the snowfall last week. Pounding the stakes into the frozen ground worked great. I was very impressed. Unfortunately it's much harder to get them out. I suppose it's a testament to their staying power but when I tried to remove them I had to really pull and this was all I got. Actually I had 4 to begin with and it only happened on half the stakes so it wasn't a total loss.

One of the good things about buying gear at REI is their return policy. You can return anything at any time in any shape. Sometimes this gets abused I'm afraid, leading people to joke about REI standing for Return Everything Immediately. In this case I felt justified since my stakes had failed on the first use.

So instead I got some MSR Ground Hogs. These aluminum stakes aren't as light or as long as the Easton stakes but they are all one piece so they can't come apart. And they still have the cord attachment rather than the shepherd's crook. I've talked to people who use them and they all say they are really strong and can take a beating. I won't often need that kind of toughness since the ground isn't often frozen in these parts. But I do need it occasionally.


Actually the best thing to do is often to use no stakes at all. If you can find trees or bushes to tie your guy lines to then that is stronger than any stake. I really try hard to pick a spot where I have things to tie to. Sometimes if there isn't a tree in the right place you can find a heavy fallen tree limb and drag it to the spot. Backpackers who often camp in deep snow really like this method because you can't find any ground to pound into. There are stakes that are designed for holding in snow but I have no experience with them.

There's another trick that I have used when I'm concerned about my stakes not holding. The worst wind I ever camped in was early last spring with Kimberly. We hung our hammocks right next to each other so we could talk. Good thing too since we didn't get a wink of sleep. The wind was gusting to 45 mph and the sound that a tarp makes in that kind of wind would wake the dead. The campground was very sandy and so I was concerned the stakes wouldn't stay. Fortunately there were large rocks around. I pushed the stakes into the ground and rolled a large rock on top of each. The wind didn't yank the stakes out of the ground all that night although it tried pretty hard.

Fallen Giants

I, like most of you, have a list of blogs I like to read regularly. Two of my favorites are sectionhiker, by a fellow hiker from the Boston area named Philip Werner (on the boards he goes by Earlylite), and Ozark Highlands of Missouri, by an ecologist named Allison Vaughn. A few months ago Earlylite posted an entry about a book he had read called Reading the Forested Landscape: A Natural History of New England. I haven't read the book but it sounds facinating. Often as I'm hiking in the Ozarks I will look around at the forest and wonder "what happened here? why does it look different than it did a few miles back?" By reading Allison's blog I'm learning more about the ecology of the Ozarks and I'm learning to understand what I see better.

Here's a sight that I often see along the trail. A fallen forest giant that has had it's very roots ripped out of the ground.

This was a pretty common sight on my Middle Fork section hike. In fact in that post I showed a picture of my camp that just showed my bivy and tarp. But zooming back a bit you see that I was camped right next to one of these fallen giants.

In fact I was in between two of them. Here was the view looking out from my camp.

Natalie and I saw lots of fallen trees on our Buford Mountain hike also. At first I didn't know what to make of it. But after reading Allison's blog recently it hit me.

Here in Missouri (and all over the Midwest really) we occasionally have winter ice storms. An ice storm is where rain falls and freezes immediately on the first object it touches. The ice build up on limbs can be pretty heavy. In the city that means power outages. But within a few days the repairmen have come with chainsaws to remove the fallen limbs and trees and fix the lines. In the forest the trees just stay where they fall.

I think that's what has happened in these pictures. That would explain why it's the biggest trees that fell (even though they appeared to be healthy and not diseased). They tower over their neighbors and so collect the most ice. Then, if they are leaning slightly, that weight uses the long trunk of the tree as a lever and rips the roots out of the ground. That's how the forest removes the tall trees and makes room for new ones.

There's one more thing I wonder about though. Often these trees fall across the trail and then the trail maintainer comes through and cuts a chunk out of the fallen trunk so a hiker can get through. Often the trunk is hollow at the time. At least I guess this must be true because these cuts don't look very old.

I wonder what this means. Are all tree trunks hollow? Or does this indicate some weakening of the tree due to age or disease? I still have lots to learn about the forest before I really understand what I'm seeing.

Stove Systems

In an earlier post I talked about my gear and briefly mentioned my alcohol stove system. I call it a system because the combination of the stove, pot, fuel, fire starter, and carrying case are more than the sum of the parts. It's clear why you need each item but you also want some way to carry them so they don't rattle in the pack and so that the individual items are all easy to get to. My SVEA 123R is a very clever white gas system that incorporates the pot, stove, fuel container, and windscreen in one compact bundle. It's even more important for a lightweight stove like a pop can stove. These stoves can be easily crushed in a pack and then won't work properly. After struggling with these issues and looking online at what other people were doing I came up with a system that I like quite well. Apparently other people were thinking the same way because now you can purchase similar kits from several online retailers.
The individual pieces are easy enough to assemble yourself. For a pot I use a 24 oz Heineken can (I don't drink beer so I had to get a friend to drink it for me and give me the can). It's very lightweight and about the right volume. In addition the thin aluminum conducts heat very well so it's quite efficient. Around the top I put some of those Livestrong bracelets so that I could pick the pot up without burning my fingers. In addition in the kit I have a windscreen, a stove, a pot stand, a fuel measuring cup, a priming dish and a ziplock container that I also use as a cozy and a bowl. The total weight is 4.7 ounces. The idea of a cozy may be new to people who have never done Freezer Bag Cooking. Basically you combine your dried food and boiling water in a freezer bag and wait while it cooks. The function of a cozy it to keep the heat in while the cooking takes place. I drop the bag into this ziplock and put the lid on. It keeps the heat in well and also serves as a bowl for when it's ready to eat.
The priming dish is the round piece of aluminum pie pan that is under the stove. I put a few drops of fuel there to heat the stove. By the time this fuel is burned the stove is heated and working well. Notice that the stove I'm using now (a Sputnik stove) has the pot stand built in. Previously I carried a homemade stove and a separate pot stand.
Inside the pot I store a lighter, a bottle of fuel, and an ultralight towel. The towel keeps the rattling down and I find I always need one handy when I'm eating anyway. The weight of the total system with full fuel bottle is less than 7 ounces.
I like alcohol as a fuel but sometimes I like using Esbit instead. Esbit tabs don't require any stove. You just need some place to set the tab and a pot stand. I had a homemade system I used to use but it didn't work as well as I wanted. So for my birthday I bought an Esbit system from Ultralight Outfitters and gave it to my daughter to give to me (we're not really into surprises around here). It's really quite cool.

It is designed to be used with a Fosters 25 oz beer can (couldn't find anyone who drinks the stuff so I had to buy it and pour it out). The tray that holds the Esbit tablet clips on to the bottom of the can and can be slide up and down. The the whole thing sets in the wire pot stand. If you want to extinguish the tablet before it's consumed you slide the tray all the way up to the bottom of the can and the flame gets snuffed out.

The windscreen works just like you would think it would. But the manufacturer suggests and additional use for the windscreen. The windscreen stays relatively cool so when you ready to pour out the hot water (or drink the hot beverage as the case may be) you grip the windscreen and pick the whole assembly up.

The white strip at the top of the top of the can is actually a strip of silicone that serves as a lip protector if you drink from the pot.
The system packs up quite nicely. You just put the windscreen inside the pot stand and then put the pot and fuel tray inside.

The fit is nice and tight so there is no rattling.

Inside the pot there is plenty of room for fuel tabs, a towel, and matches. I prefer matches for Esbit because it takes a few seconds for the tablet to catch fire. A lighter can get pretty hot in those few seconds. It's much nicer to just light a match and set it on the Esbit tablet. I use REI stormproof matches which burn very hot for several seconds and can't be blown out by wind.
There's extra room in this system for something else. I'm thinking I may make a cozy out of reflective bubble wrap as described sectionhiker here. The one thing I will be missing compared to the alcohol system is the ziplock container. That's a bit of a problem since I use it with my Steripen for sterilizing water (see my Middle Fork hike entry). I'll have to come up with a different solution for that.

Beavers?

In my wildlife blog entry I mentioned that I was hoping to see a beaver dam on my trip to the middle fork of the OT. But in the subsequent blog entry, where I document that trip, you'll notice I didn't mention seeing any beaver dams. I was really bewildered. I had seen the following pictures by Danny M (whose motrails site is the definitive guide to hiking in Missouri) which looked pretty impressive. These were taken near Barton Fen, about half-way through the middle fork section.



When I got to Barton Fen and didn't see any dams I actually took off my pack and went exploring to see if I had missed them somehow. I did photograph the following tiny thing which hardly looks like Danny's pictures of beaver dams.

I was really disappointed and worried I had somehow missed what I had come to see. Then it occurred to me that the severe flooding we had had in Missouri during 2008 may have wiped out the dams (and maybe the beavers!). When I got home I made inquiries on Danny's yahoo group. John Roth, president of the Ozark Trail association, told me that the beaver dams get obliterated every few years due to flooding. In fact the pictures on the Barton Fen gallery at ozarktrail.com are of a previous set of dams which existed in early 2002 but were destroyed that year by floods.

So it appears that flooding is an occupational hazard for beavers. It may be that the little dam I saw is the beavers attempt at rebuilding.

I learned something else as well. Beavers are kind of like suburbanites. They are always remodeling their homes. So if their dam is not knocked down by a flood in a given year then they raise the dam and make it higher. Actually this can be bad for the surrounding ecosystem because the dam pond grows and grows. So an effort was made to keep the most recent set of dams from growing. A PVC pipe with holes drilled through was laid across the top of the dam so that even if it the dam were built above it water would continue flowing through so the pond wouldn't get any higher. Thinking back I did see the end of a PVC pipe sticking out from the bank at one point. That must have been the location of the dam. Perhaps in a few years there will be another 6 foot dam on the creek.
