Homemade Pressurized Alcohol Stove For Ultralight Backpacking
In the last few days I have been researching how to build a homemade alcohol stove out of pop cans for backpacking. I found directions for several different designs at zenstoves.net and decided to try making the pressurized type. Here are some specs and the pictures documenting the process.
Specs:
2 cups time to boil: ~5 minutes
time to prime: ~10 seconds
weight: < 1 ounce
capacity: 1.5 ounces
full capacity burn time: ~8 minutes
fuel used: denatured alcohol
The two cans that will eventually become my alcohol stove.

The three primary pieces to my alcohol stove. The top and bottom parts with the inner wall that helps hold it together.
A completed pressurized stove that burns denatured alcohol and weighs approximately ONE OUNCE! It has an inner wall, is approximately 35 mm tall and holds a little under two ounces of alcohol. I used jb weld to attach the bolt and nut, the fiberglass wick and the top and bottom pieces of the can. I finished it off with some paint that can handle temps up to 1200.

Using the MSR Whisperlite Backpacking Stove
Understanding how a MSR Whisperlite stove works is essential to reducing flareups and effectively priming the stove prior to lighting. The most important part of the process is how the fuel, white gas, changes from liquid in the bottle to a gas that burns with an intense flame. New users are often intimidated by the MSR Whisperlite, but if taught properly, there should be no problem lighting the stove.
Pressurizing the Fuel Bottle
White gas is stored as a liquid and put under pressure in the fuel bottle. The pressure, created by the fuel pump, forces the liquid white gas through the metal tube into the stove. Pumping the fuel bottle until resistence is felt will result in adequate pressure. The number of pumps will depend upon the amount of fuel in the bottle.
Heat Feedback
If you look closely at the path of the white gas, you will notice a loop that takes the liquid fuel above the flame
when the stove is operating. This is an essential stage called heat feedback. Heet feedback means that when the stove is burning, the flame heats the white gas up to the point that it turns from liquid to gas, much like water changes to steam at water's boiling point. Here is a diagram of that change from liquid to gas.
This process occurs when the stove is already started and burning. But how do I get to that point, where the gas is hot enough that it changes from liquid to gas?
Priming the MSR Whisperlite Stove
This is where the primer cup comes into play. If the white gas is still in liquid form when it makes it through the fuel line, it will collect in the primer cup. The liquid white gas in the primer cup then should be lighted with the fuel valve on the bottle closed. Lighting this heats up the very end of the fuel line and some of the remaing fuel in the line, creating enough heat to change the liquid to gas. This heated gas rises up through the stove and starts making a slight hissing sound. You may have to experiment with how much fuel is allowed into the primer cup to do this.
Lighting the MSR Whisperlite Stove
The next step, lighting the stove, is often made much more difficult than is necessary. The easiest method is to simply wait for all the fuel in the primer cup to burn up, turn the fuel valve back on, and light the stove at the top, much like lighting any gas grill. The stove may burn with an intense blue flame right away, but sometimes the heat feedback, mentioned earlier, needs a little longer to be completely effective. The more difficult method is to turn on the fuel while there is still liquid white gas in the primer cup, but enough heat to for the hissing sound to be started. It is a matter of timing.
Advanced MSR Whisperlite Techniques
Simmering can be achieved by reducing the pressure in the fuel bottle after the stove has been started and heated up. Turn the fuel off, let the flames burn out, and twist off the fuel pump until pressure is relieved. Afterwards, simply pump the bottle fewer times than you normally would and light the stove again.
MSR Whisperlite Maintenance
The most effective and common maintenance for the MSR Whisperlite is to simply shake. At the very end of the fuel line is the shaker jet, a tiny needle that is free to move up and down. By shaking the stove, carbon buildup is removed. The shaker jet should make a slight rattling sound.
The second most effective and common maintenance for the MSR Whisperlite is cleaning the fuel line. Cleaning the fuel line consists of pulling out and pushing in the cable that is within the fuel line. This removes the carbon buildup that limits the flow of fuel. You can use different tools for this, but the one that comes with the stove
works well. If this is done regularly, it is a simple task and the cable will freely move. If not, it may take considerable effort to get it all the way back in, repeating the in and out until all carbon has been removed. Be careful not to damage the cable.
Safety Considerations
1. Watch for leaks from the fuel pump and check o-rings.
2. Do not step, lean, or reach over the stove.
3. If there is too much fuel in the primer cup, leave the stove and let some evaporate prior to lighting.
4. Always handle boiling water carfully.
5. Do not use water to put out white gas fires, smother the fire with whatever is available; dirt, aluminum wind screen, pot/pan, etc..
6. Keep food and fuel separate. Some fuel will remain in the fuel line after the stove is out and needs to be drained appropriately.
What Next?
If you have mastered the workings of the MSR Whisperlite stove, I suggest you try making a pop can alcohol stove that weighs about one ounce!

Best Tea Infuser and Travel Mug
I would like a combined travel mug and tea infuser that would allow me to put some loose leaf tea in the mug, boil some water, and take off instead of waiting for it to completely infuse and then dump in a travel mug. I cannot find anything that meets my requirements.
Requirements:
-Glass/Ceramic Construction (No Plastic)
-Double wall if glass
-Can stop the tea from continuously brewing (No Bitter Tea)
-Durable
-Can drink from while on the move or driving (No Spills)
-Can remove loose leaf tea without making a mess or having a sink (Built-in Storage)
Any Suggestions?

Wakulla River
I went on a riverboat tour of the Wakulla River at Florida's Edward Ball Wakulla Springs State Park. The wildlife was amazing but the water was a bit too cold for much of a swim. On the boat ride, I spotted alligators, ducks, birds, fish, turtles and tons of other wildlife. I only wish it was more than an hour ride. Here are some of my favorite pictures:

Backpacking in Shenandoah National Park
Eight things to know before backpacking in Shenandoah National Park:
1. A free permit is required for overnight use, but you may camp almost anywhere in the park. Permits can be obtained at entrance stations, visitor centers, both ends of the Appalachian Trail in the park, and Old Rag fee station.
2. Open fires are not permitted in the park. Although you may enjoy the experience of a fire, fires are restricted for ecological reasons to protect the park.
3. The most popular backpacking areas are the Appalachian Trail and Jeremy's Run. The AT accounts for over 50% of backpacking use and Jeremy's Run consistently leads all non AT trails for destinations. If you want to avoid crowds, check out the south district of the park.
4. Several areas are off limits to backpacking including the Whiteoak Canyon Trail, Limberlost Trail, Old Rag and Hawksbill Summit, and Big Meadows. Backcountry regulations stipulate that you also camp a quarter mile from Skyline Drive and the park boundary. You also must camp one half mile from park structures such as Rapidan Camp.
5. Shenandoah National Park has undergone significant ecological change in the last few years as hemlocks continue to die and the forest recovers from the 2000 fire which burnt over 20000 acres. Many parts of the park may appear to be great campsites according to a topographical map, but the lack of a forest canopy has drastically changed many areas. Instead of open forest understories, you now find thick mountain laurel and new growth. You've been warned, now don't forget about those widow makers either.
6. Less popular but great trails can be found. Examples include White Rocks, Thorton River, and Big Run. You really can't go wrong with any trail you pick in the park.
7. Bears, snakes and poison ivy. While working in the park for the last summer, I was far more concerned about where poison ivy was than bears or snakes. Although the bear population is very high, most of the bears are well behaved. The nuisance bears are quickly relocated and are often found at the frontcountry campgrounds anyhow. For snakes, there are a few spots in the park where you are likely to come across a few copperheads or a rattler, but sightings are usually limited to snakes sunning themselves. Just go around them when you see them. Watch out for poison ivy!!
8. Although these aren't the highest mountains, most hikes usually begin from Skyline Drive and head down the mountain and then back up. Just remember that it's a lot more work going back up than it is down, especially on a hot and humid summer day.
If you have any questions about the park, I'll be happy to answer them, just leave me a comment.

Inov8 Roclite 295 Trail Shoes - Gear Review
I recently purchased some shoes from Innov8. I selected the extremely lightweight ROCLITE 295. I was immediately impressed with the weight of the shoes, a little under 12 ounces for a size 11 mens on my scale for one shoe. I have never had anything so light that wasn't a sandal.
I quickly put them on and took off for a short run/hike and am happy to report the flexible, but supportive feel that I prefer in my hiking shoes. The shoes allow me to feel the trail unlike hiking boots. The sole of the Inov8 Roclite 295 is very aggressive and will do great in muddy and slippery conditions; although, I haven't tested them out on wet rock so far. One negative is that they are not non-marking soles.
The shoes have a very breathable mesh upper that should strike a good balance between breathability and keeping rocks and or dirt out. These shoes are not goretex or waterproof.
Overall, I am extremely pleased with these shoes. The Inov8 Roclite 295s will be put to the test as I try to find an ultralight hiking shoe for my thruhike of the continental divide trail in 2009.

SCA Idaho Workskills 2009
I just finished up teaching SCA workskills along with three other instructors for the last week. I taught the tread and drainage station each day. We built waterbars(rock and timber), constructed reverse grade dips, cleared slough and reshaped backslopes. It was fun although as an instructor I would have liked a project that built on the previous days work rather than starting fresh each day. Here are some of the pictures of the SCA members hard at work. You can see more in my SCA Trail Workskills photo album.

ArcTeryx Bora 80 Backpack - Gear Review
I have owned my Arc'Teryx Bora 80 backpack for over a year and am satisfied with the pack. It has met all of my expectations and then some in terms of durability, quality, and load bearing. I purchased the pack not for a desire to be ultralight, but for my job leading trail crews. I often have a huge load, well over 50 pounds, and I need a backpack that would handle the beating. I have also been using the pack on shorter backpacking trips where I was not concerned about the extra size and weight. It is an indispensable part of my collection of backpacking gear!
What do I like about the pack? The pack itself is of the highest quality. I have no rips, tears, holes or any other signs of wear. This durability is after I have slid the pack down a scree field in Death Valley NP, used it to carry various trail tools to job sites, and regularly used it as my checked luggage on cross-country flights. The attention to detail is what separates the Arc'Teryx Bora backpack from others. The quality zippers are just one example of that.
I find the large outside pocket extremely useful for keeping anything that I may need quickly or need to keep out of the main compartment; for example, a wet rain-fly. The 'brain', top compartment, is also large enough for my 'necessities'.
The most important quality of this pack has been that it performs exceptionally when loaded with a huge load. I can easily adjust the weight how I want and can transfer it to my hips without any problems. On a trips in the southwest US and due to water weight, I have carried 70-80 lbs as if it were only 40 lbs.
What don't I like about the pack? Not much really. I never use the side zipper. The shoulder straps and hip belt are a bit stiff. It is heavy, but that is expected and needed for a pack of this size and durability. Price. All of my complaints are relatively minor in my opinion.
This pack has seen some beautiful places... Lost Lake, Chugach NF, Alaska...

Canon 5D Mark II Video Skipping
I recently upgraded to the Canon 5D Mark II DSLR and couldn't be happier that I did. But one of the first things I noticed with the camera was that the video skipped when I played it on my computer no matter what player I tried. I couldn't figure out what the problem was...
After a little research, I found the answer and it is the best possible answer you could get... the video is too big and too high of a resolution for my computer to actually play.
Great, so what's next???
Convert the 1080 HD video down to a quality that you can play. I use MPEG Streamclip, it's free and simple. I just convert it down to a 780p HD video and it's good to go! No more skipping!
Why Are My Photos Blurry?
There a few reasons why your photos may be blurry or out of focus and with a couple tips you can make sure your pictures turn out amazing and super sharp.
1. The object in the photo was moving.
Example: If a sprinter can run 100 meters in under 10 seconds and you are using a 1/4 second shutter speed, he or she will have traveled over 2 meters in that time. But at 1/1000 of a second, that sprinter traveled only 1 cm.
Solution: When taking photos of fast moving objects, I set my camera to a specific shutter speed, usually 1/200 or faster, and let it adjust the aperature and iso automatically given the lighting conditions. Another solution is to simply move the camera with the object before and after taking the photo. This will create a sense of motion in your photo as the object will appear in focus while the background will be blurry.
2. The camera is moving or shaking.
Solution: Use a tripod if possible. Better yet, use a tripod with a wired remote. Best, use a tripod with a wired remote and mirror lockup enabled if using a SLR. Not all camera's have this feature but it prevents the mechanical movements within the camera from causing vibration. If you do not have remote for your camera, you can always use the 2 or 10 second delay for the same effect. As in problem number one above, your shutter speed will also affect whether you need a tripod or not. A shutter speed anywhere close to one second long will be blurry unless you have a tripod. Check out this link on how to avoid camera shake.
3. Part of the picture is in focus, but everything else is extremely blurry.
Solution: Adjust the aperature accordingly. A wide open aperature (smaller number) is going to create bokeh which may sometimes be desired. However at extremes, there will be such a shallow depth of field that for example one pedal of flower may be in focus, but the other one is not. Setting a specific aperature and allowing the camera to adjust shutter speed and iso will allow you to take control and style your photo as you desire.
4. The camera is not focused on the correct object.
Solution: There are several possible solutions to this problem but they may not be successful in all scenarios. First you can try the focus lock method by pointing the camera directly on the desired object and then recomposing the picture while holding the trigger button half way. This makes it easier for the camera to find the object. Second, you can change the autofocus mode to have the camera adjust its algorithms for tracking objects in motion. Another possibility is to try and use the manual focus. If your camera has a liveview setting and you are using a tripod, you can zoom in digitally and adjust the focus manually far more accurately than you could with the viewfinder. A smaller aperature (bigger number) will create a larger depth of field and allow more of the frame to be in focus and sharp.
These are the root problems that may make your photos blurry or out of focus. Often you can make adjustments to correct for these problems and if you know to expect them, you will take great photos. Higher end equipment is undoubtedly better at creating sharper images, but there are numerous techniques to try before spending more money.

Granite Gear Latitude Vapor Backpack - Gear Review
The Granite Gear Latitude Vapor Backpack has been my lightweight backpack of choice for a couple years now. It weighs in at 2lbs and 10 oz and while not ultralightweight, it is respectable. It is a very simple pack that doesn't have a bunch of unnecessary pockets, straps, or loops.
Specs:
Weight: 2lbs 10oz
Capacity: 3800 cubic inches
Load Capacity: 30lbs
Retail: around $190
The backpack has decent support given its weight and I have carried much more than the maximum 30 lb capacity that is specified by Granite Gear... more on this in a bit. One feature I greatly enjoy is the full length double zipper that allows me to access the entire contents of my backpack compared to the standard backpack that is top loaded.
I have had some problems with this pack in terms of durability. I have busted the hip belt buckle and have noticed some serious tears that would render the pack useless without some repair. Some of the durability issues are my own fault as I have had more than the specified weight capacity in the pack; however, in my opinion it is still unacceptable. The most serious tear is where the padding on the back connects to ripstop nylon near the top of one of the shoulder straps. You can see it in this picture...
That is a very important spot and will be a pain to repair. Since this is my first lightweight backpack, I think I have learned some valuable lessons about not abusing my gear and selecting gear that will meet the demands I have of it. Thus is my reason for purchasing an Arc'Teryx Bora 80!
Here is a picture of me with this pack in the Gila National Forest on spring break. Gila Wilderness Backpacking Trip Report, Trip Info and Gila NF Slideshow. Overall, would I buy this pack again. Probably, but I would seamseal those corners with silicone.

Photography Is Taking Over My Life
It seems as though I am spending more time and money with photography these days. I am waking up to shoot at dawn or pull the camera out in the moonlight on long work days. When I am not working, I'm heading to St. Marks Wildlife Refuge or Wakulla Springs. I still have a bunch to learn, but I am having a great time with it and getting better. Much better glass has helped too!
My Gear:
I am currently using a Canon XSI with a 24-70 f2.8 for almost all of my pictures. I shoot this on the Gitzo 2440 Carbon Fiber Tripod with a RRS BH40 ballhead and L plate. I cannot stand using my older cheaper lenses anymore and will soon be getting a 70-200 f2.8 to compliment my setup. After that I will probably get some much needed accessories such as an external flash, polarizing filter, telephoto extender and neutral density filter before upgrading my camera body or purchasing a longer lens.
What I am currently trying to improve upon:
1. Setting depth of field
2. Increasing sharpness
3. Processing RAW images
New Photos
Backpacking Movies
The other day I started looking for some movies/documentaries that involved backpacking or anything that just had some great wilderness video. So far, I have found the following not in any particular order:
1. Touching the Void - an amazing documentary about two climbers trying to climb an almost impossible peak in Peru. awesome video and pictures of the mountains.
2. Jeremiah Johnson - great older movie about a man who escapes to the mountains to become a mountain man.
3. The Edge - two men try to survive in Alaska after a plane crash.
4. Other Mountaineering: K2, The Eiger Sanction, Everest
5. Grizzly Man - documentary about Timothy Treadwell living with the bears in Alaska.
6. Deliverance - not really one about backpacking but should be watched.
7. Never Cry Wolf
8. Continental Divide - City guy(John Belushi) is sent to the Rockies to hide from the mob and falls in love with an eagle researcher.
9. Into the Wild - "After graduating from Emory University, top student and athlete Christopher McCandless abandons his possessions, gives his entire $24,000 savings account to charity and hitchhikes to Alaska to live in the wilderness. Along the way, Christopher encounters a series of characters that shape his life."
I haven't seen all of these yet, but I have to say, they really make me want to head out and go backpacking.

Combined Elevation Profiles: CDT, PCT, AT
Here is a great page comparing the elevation profiles of the three major long trails. It is an interesting perspective on the difficulties of each trail.

Horse Creek Trail Maintenance - Frank Church Wilderness
I recently spent an eight day work hitch clearing brush and cutting blowdowns with crosscuts on the Horse Creek Trail in the Frank Church - River of No Return Wilderness. Horse Creek empties into the Salmon River about five miles down river from the confluence of the North and Middle Forks of the Salmon River. We cleared brush for a little over 6 miles and my arms haven't been so sore for quite awhile. It was still a great time and we saw a ton of wildlife; elk herds daily, black bears, mountain goats within a couple hundred yards, and a wolf.
The elk herd was on the ridge in the distance.

Pictures Featuring My Tent
When showing pictures from my many backpacking trips, one of the parts I like to point out is my campsite location and what I wake up to in the morning. Here are some of my backpacking photos featuring a tent:
Washakie Pass in the Wind River Range
Another picture from the Wind River Range in Wyoming
Joshua Tree National Park after a little snow
Caramba Point Overlook near San Jacinto in southern California
My sleeping spot for nearly 8 months in the Yuha Desert in far, far southern California. Mt. Signal in the background is in Mexico.
Here is the rest of our camp in the Yuha Desert.

Trail Building Job with the SCA
The SCA is taking applications for trail crews on the Salmon Challis National Forest including the Frank Church River of No Return Wilderness. I will be leading one of the crews! Here is the position summary from the SCA:
Help restore, protect, and enhance recent burned areas in the central Idaho mountains. SCA is looking for 10 energetic, adventurous, hard working, high spirited, individuals interested in getting their hands dirty completing a vast array of trail projects in the Frank Church River of No Return Wilderness and surrounding areas. Project location will be the Salmon Challis National Forest. Term of service is 3 months and much of that time will be spent in various backcountry and front country settings, camping and living in a tent. Hiking and backpacking required. Plan, manage and complete trail construction projects, 80%; prepare for field hitches, 20%. A community spirit and teamwork is paramount to the success of the project.
I know that after looking at some of my trail work pictures, I can't wait to get back out there and do some work! I think it has to do with the incredible amount of effort and attention to quality that I put into these projects and the awesome results, not to mention the location of the work!

War on Wildlife, Wildlife Services
If you have not heard about Wildlife Services, a branch of the USDA, you should read this report by WildEarth Guardians that is being presented to Congress and the President. Wildlife Services are the ones responsible for killing wolves, grizzlies and numerous other predators to often protect livestock grazing on public lands. It is costly and controversial and subsidizes an industry at the expense of a more natural ecosystem. In some situations, predators are targeted solely to increase the number of elk and other species for hunters. You can read about one such example at wolves.wordpress.com.
Authors of the 108-page report being presented to USDA, members of Congress and the White House on Tuesday described it as the first comprehensive, national, independent assessment of the agency in 40 years.
In sum, each year, Wildlife Services kills tens of thousands of wild animals and pets,endangers public safety and the safety of its own employees, and spends millions of tax dollars (local, state, and federal) to do so. The 1994/1997 PEIS upon which Wildlife Services relies is anachronistic. Despite the $100 million annual investment in killing over one million animals each year, the GAO, and independent researchers and an economist have shown that the program is ineffective, and the costs outweigh any perceived benefits. Wildlife Services kills wild predators by the thousands using controversial and dangerous methods in futile attempts to bolster the nation’s declining sheep industry.
