Sunshine and snow melt on the SHT

I spent Feb. 26-28 on my favorite section of the Superior Hiking Trail: Beaver Bay to Highway 1. The weekend was fabulous - the weather was warm, and with the exception for Sunday morning, there was no cloud in the sky. The weather was so warm throughout the weekend, I hiked in my base layer top for most of Saturday afternoon and Sunday morning into the afternoon. Rarely did I have anything else on my torso besides my top and sunglasses.

I was the first obvious human visitor to the area between somewhere south of Penn Creek and Mt. Trudee in a while. The trail was obvious because of prior indentations (and subsequent snowfall), but there were no fresh tracks. The trail register at the east fork of the Twin Lakes Trail confirmed that what I thought: I was the first person to make an entry in the log since jan 2, 2010, a span of eight weeks.

I also saw only one person physically on the trail, and he was out walking his dog. I saw no other hikers. From my vantage point atop the adjacent ridges, I saw some persons icefishing on Bear and Bean lakes, and two cross country skiers on Bear Lake.

There were at least more recent visitors in the section between Penn Boulevard and Penn Creek. Unfortunately, some snowmobiles south decided to carve their path on the SHT. It made walking easy, but it does not lessen the intrusion. The SHT crisscrosses numerous snowmobile trails, and the trail clearly marked with "Foot Traffic Only" or "No Motorized Vehicles." Signs mean what they say: snowmobilers, stay off.

The trail section between Mt. Trudee and through Tettegouche State Park to Highway 1 was much more compacted, likely because of visitors to the park. The compacted trail pretty much started at the summit of Mt. Trudee and wound its way back through the park.

Somewhere in Tettegouche State Park in amid its cedar forests is a climb dubbed The Drainpipe. It is the toughest single climb on the SHT, and and it reminds me of the Hillary Step, a 40-foot climb on Mt. Everest only 269 vertical feet from the summit (although no where near as difficult). To climb up this section, I had to click up the heel bars on my snowshoes and take it one slow step at a time. This photo does not do it justice.

Because I did an out-and-back, I had the pleasure of going down and then up the Drainpipe. I can compare the two only as such: going down was likely more dangerous because my feet could have more easily slipped out from underneath me (landing me on my butt), but going up was harder because of the single-step/rest-step method I used to get up.

It was the second weekend out with my Betalight. I had initially wanted to modify the anchors by adding ladder lock buckles to the corners, but I did not get the chance to do that before I left. This would allow me to get a tight pitch, and to tighten the pitch throughout the evening should the silnylon sag or the snow shift. Instead, I pitched the shelter as tight as a could, then set up the shelter. My poles (115 cm Gossamer Gear LightTrek 3s) were too short to get a tight pitch, so I had to add rocks under the poles to boost them slightly. This tightened the pitch, and created vents along the base of the shelter because the pitch was not tight to the ground.

I spent Saturday evening on a hill just outside the park boundaries. The moon rose over the lake, leaving a glow over the lake and throwing shadows from everything. It was one of the best campsites I've been at in a while.

Being on top of a hill, it was breezy. I closed up the door to keep drafts off my chin and expected heavy condensation on the interior walls throughout the night. But when I woke up, there was minimal condensation on the interior walls, just some mild condensation directly above my face. The ground-level vents created by the pitching method created sufficient ventilation to prevent an icing, too.

Here is my Final 2.26-2.28.10 Gear List (Google Spreadsheet). You'll notice that I have not calculated my base weight. This was not intentional, but in hindsight it is less important in winter because your clothing system changes throughout the day - you're simply adjusting layers more often.

I made two last-minute gear-list changes: In my initial gear list, I cut out my SMC Snowstakes to save approximately 8 oz off my pack weight. But I added them back in out of sheer convenience. I also listed my sole base layer bottom as a pair of GoLite Stride shorts. But I brought along (and wore) my new Patagonia R1 Bottoms instead because I wanted to have a base layer over my knees.

Taking the snowstakes was the correct decision. I got into camp Friday night at around 12:30 am, and the stakes were convenient. I did not have to go searching for sticks, and the stakes sliced into the packed snow of the designated campsite. However, I should not have worn my R1 bottoms. The temperature was too high for their use, and I was sweating on my legs throughout the day. That all said, as soon as I stopped the bottoms dumped heat, just as the fabric is designed to do.

Because of anticipated weather conditions, I switched from my MSR Dragonfly, a white gas stove, to an MSR PocketRocket, a top-mount canister stove. Canister stoves are not traditionally used in the winter because the temperatures tend to be below the boiling point of the fuel in the canister. I use MSR canisters (almost exclusively), which contain a mixture of isobutane and propane. Isobutane boils at +10F, and propane boils at -43.8F (chart from BPL). Like white-gas stoves, the fuel for a canister stove must be in a gas form to burn efficiently. Thus, when the temps drop below +10F, the canister will start to burn propane almost exclusively, and when that fuel runs out, the stove stops dead. Now, take into effect Boyle's law (as pressure decreases (through using the stove), the temperature decreases) and the canister can cool below +10F and cause the stove to stop working despite the canister being two-thirds full.

The weather cooperated with the stove. The daytime temps were in the mid 20s to mid 30s. I also warmed the canister inside my jacket, and on Sunday (photo posted above) I kept the sun shining on the canister throughout the snowmelt.

It takes about the same amount of fuel to melt snow as to bring 40F water to approximately 180 degrees. According to BPL testing, the PR used an average of 8.3 g of fuel to bring 16 oz of water to a boil under optimal conditions. My testing is yields similar results.

I was surprised by the stove's performance: I used 93 g (of a full 227 g canister) to melt approximately seven cookpots of 25 oz water. I also boiled a small amount of water for oatmeal on Saturday; this amount is not included in the calculations below. I was using the MSR Titan Kettle, which holds 850ml/28.75 oz of fluid brim-full, and my melts were mostly full, but never brim full. Thus, I believe my fuel consumption and water melting data are conservative estimates. All total, I melted 175 oz, or approximately 11 pints, over the course of 48 hours. Running the numbers, I used approximately 8.45 g/pt.

Finally, I did have one major problem with my boots because my feet were wet from Saturday afternoon until I got to my car on Sunday. The snow was melting and despite the GoreTex liner in my boot, my feet were wet.

Problem diagnosis: I do not think snow got in over my boots because I was wearing over-the-calf gaiters. My pants were wet on the outside of the lower part of the gaiters, but this is from condensation on the inside of the packcloth of the gaiters. I do not think it was from excessive perspiration. I was wearing heavy winter socks (SmartWool Mountaineering), but my right sock was wetter than my left (on both days) and on Sunday afternoon (in the sunshine, temps well north of 32F) I wrung water out of my right socks. I think there is a failure of the Gore-Tex lining (similar to the hole I wore in my Saloman on the SHT in 2008), and I'm going to contact Innov-8 to see if it is a warranty issue. I love the boots, but this is unacceptable.

Trail running = hard

Afton State Park evened the score this weekend. It is Tuesday, nearly 48 hours after my ~12 mile trail run up and down the park's hills, and my quads were bothered this evening by a slow 5.25 mile jog.

I now understand the phenomenon of "Dead Quad," where one's quadriceps muscles are so shot from running down hill that forward progress is a monumental task. The outsides of my legs ached; when my feet hit the pavement, it felt like my bones were solid rods incapable of absorbing shock. So I ran no further. Tomorrow is another day. Now home, I pumped fluids and took some Vitamin I.

The 50K is just over three weeks out. I do not plan to do any substantial taper, just run 45-50 miles/week for these final three weeks. I'll hit somewhere between 60 and 70 miles this week, and that will be the max for this race. And then the post-race recovery.

My parents are playing crew for me over this race. Their love and support got me through the 2008 Twin Cities Marathon, and their presence is a powerful stimulant.

50K trailrace here I come - signed up for Superior Trail Race

Ultramarathons, here I come. I signed up for the spring Superior Trail Race 50K this evening after putting off registering for a few weeks. 50K is 31.4 miles, 5.2 more than a marathon and on a significantly differently path. The route is full of some of the larger elevation gains on trail, especially in the first five miles or so - because the route is an out-and-back, the last five miles or so, also.

That said, it is nothing I cannot handle - it takes patience, training and a mental attitude that I honed in the TC Marathon. I have been setback on my training because of a minor right ankle injury and a headcold, but I am back to running now and should be getting into some more serious training regimes ahead.

I am incorporating weight lifting into this training season, and I will get around to doing serious hill work eventually; I just need to find a good set of hills in my area that would accommodate my need to vertical gain. I am doing most if not all of the exercises recommended to me by my cross country coach in high school, and an emphasis on high rep counts at reasonable weights.

My brother has tentatively agreed to head up my trail crew - my faithful girlfriend will be unavailable for the weekend as she has other plans she must attend to. Trail crews will be allowed access at four aid stations along the trail - two on the way out and the same spots on the way back. For me, that is at mile posts 7.6, 13.3, 17.7 and 23.4. This will be a change of pace for me from the marathon, which had aid every mile and medical stations every three miles. His job: make sure I have water, salt and carbs. And stop me if necessary. He is a person whose judgment I trust in a situation such as this; a trust I know I can hold on to even in a severely depleted state.

Looking at the SHT topo map, there is no realistic way to get aid to a runner during those final 7.6 miles from the last aid station to the finish. That distance, 5.9 of which pushes the race into the ultramarathon category, are the miles I am concerned most about. Running in the TC marathon, my quads gave out at mile 16 and my hamstrings gave out at mile 21. At that pace, I'll only be two-thirds of the way through with the biggest descents before me en route to the finish.

Finally, I'm going to guess I'm going to go through at least two pairs of shoes before the race and finally kill my two original pairs of SmartWool adrenaline mini crews. We'll see when May comes.

If you're going to be in the area and would like to volunteer for the race, email Mike Perbix at mike.perbix (at) gmail (dot) com.

Gear reviews from SHT

The high temps (mid 20s) and the hard work overwhelmed my clothing system while hiking the first day. I sweated out my base layer and softshell clothing in my hiking - the snow coming down did not help. With these conditions in mind, I offer the following reviews.

Starting from my feet, my sock combination kept my feet warm - I wore X-static socks, ID VBL socks and then Smartwool Mountaineering socks as warmth socks. All of these were inside my Steger Mukluks. There was little moisture inside my VBL socks when I took them off when I went to bed on night zero. There was a little moisture in my liner socks, but these dried out overnight in my bag.

The mukluks performed well but not flawlessly. The leather laces, moosehide I think, stretched and absorbed water as they sat in my tent overnight. Temps in the tent were high and melted the snow that was attached to them - the laces absorbed it right up. The next morning when I went to my boots on, I pulled one of the laces too hard and it snapped! I lost about a 5 inch chunk of leather. This was not a huge deal because the laces are about three feet long and stretched, but it did prevent my from getting an optimum snug fit on my other foot because I did not want to repeat the breaking. Also, when I was at the cafe in Hovland, the snow on my mukluks melted and soaked the canvas and the leather - this in turn got my warmth sock wet and made my feet cold. I changed into dry socks and wore a pair of boots that were in the car for the ride home. This would not be a problem had I stayed outside, however on the trip I would have needed to go indoors at least twice to get resupply packages. On colder trips, this obviously would not have been a problem.

My softshell pants, a pair of Marmot Scree softshell pants performed well. They repelled snow and exterior moisture beaded up on the outside - however, they did wet out from sweat from my hard hiking on day zero. I did not have this problem on day 1 (Sunday), so I belief this was caused by the warm temps. Each day I was wearing a pair of trusty thin base layer bottoms (Theramar poly pro) underneath. At night, I wore the pants over my VBL pants in a successful effort to dry them out. The fabric is sufficiently stretchy to accommodate a wide range of temps and they are great pants. For $99, they are highly recommended (and not, I did not pay that much). I currently use these pants when I bike to work on a twice and soon-to-be thrice weekly basis and they do a good job breathing and cutting moderate wind.

My softshell jacket, an REI Mistral with PowerShield fabric performed well but is flawed in that it does not have a hood. (related: my rant on rain hats and how useless they are.) Like the pants, they wetted out from sweat but generally, snow bounced off the jacket. Snow that did land melted and the jacket dried quickly. If it had a hood, it would be great - the jacket is very lightweight for a softshell jacket, uses quality materials the construction is decent. The jacket would be excellent if the cut were narrower and if it had pit zips. (Note: You can get all of this and more at Beyond Clothing, where you can customize your own clothing, including softshells.) At night, the jacket was soaked through and through and I put it between my pads to keep it from freezing. I needed to take it off because when I was in camp, I could not dry it out underneath my down jacket without compromising the insulation. More on that later, but I eventually brought the jacket into the sleeping bag and it moderately dried out overnight and was wearable the next day. It dried out completely while I walking out.

That all said, I am now convinced of the value of softshell clothing in temps respectfully below freezing (below about 20F, to use a semi-arbitrary temp). Any more and a hardshell might be preferred. For those of who have read my doubting of softshell clothing, consider this an apology - you were right, I was wrong, now lets all going hiking and forget about it. A softshell may not even be necessary, however, if one goes with a light hooded base layer and a breathable windshirt with a decent DWR - more on this in a later post.

My VBL clothes really had no use in the high temps I experienced. I wore them overnight next to my skin and underneath my softshell pants because they would keep exterior water from getting to my skin. I also tried to wear the jacket briefly on the first day of planned hiking (Sunday), but took it off after getting too hot. I think now that VBL best used when the body is in low metabolic states (i.e. not hiking). I did wear the shirt successfully in 0F degree weather at winter camp training while walking around, but I did not have a pack on and the walking was not strenuous. VBL is still necessary to keep insulation dry - much has been written on this and will not be repeated here.

I made a balaclava out of Epic fabric (which I goofed on and generally did a poor job constructing) but it worked well as a hood substitute. The fabric was moderately breathable and showed good potential for wider uses as a windshirt-on-'roids, a la Wind Things.

My snowshoes, a pair of 25" MSR Lightning Ascents, did me little good on the snow. Many people have suggested to me that I should have used bigger shoes, and I think they are right. I should have gone with a pair of 30" shoes or an even bigger pair. Atlas makes shoes that are 35" long, Crescent Moon makes a 37" pair and of course there are the old military surplus-style ones. That all said, I don't think any pair of snowshoes would have allowed me to wade through that snow effectively. It was just too deep to make any progress and it was light and powdery. The problem was that there was a lot of it and that made it heavy. I could have used two or three feet less snow, and the fresh snow that fell on night zero did not help.

My ID MK1 performed the best of any gear I brought along. I failed to get a solid pitch on night zero but the tent help up to winds without budging and shed snow with ease. The fabric was incredibly breathable and there was minimal condensation on the interior of the tent fabric (or the poles for that matter, a testament to how warm it was in the tent i.e. above the dew point) in the morning. The tent is small, but it is built for climbers. One nitpick - the bag supplied is too small so I brought a larger stuff sack. I also like to roll my tents (not stuff) which further complicates the matter.

I took a TNF Nupste as my sole puffy insulating garment for my torso. In hindsight, the jacket needs some serious DWR on its exterior shell fabric. I refused to cook in the tent, so I was outside waiting for snow to melt and water to boil and had to wear the down jacket (because every other torso layer except my VBL shirt) was soaked. This got the shell wet and probably compromised the insulation. It is a warm jacket, but the weather was too warm and snow melted on contact. This jacket shall be relegated to around-town usage. Without a better DWR, my older version does not below in serious conditions. That said, I will be testing the Sierra Designs BTU jacket, which is really a parka, this winter. It is hooded, has a wp/b shell and so far has kept me warm in some extremely cold conditions around town.

For water bottles, I used 48 oz collapsible Nalgene Canteens. I took two - one as a backup because failure would be catastrophic. I rested the bottle underneath my softshell jacket but on top of my hipbelt while I was walking and the combination worked perfectly. The canteen was easy to pour into and drink out of and the collapsing was nice. For purification, I took chlorine dioxide tablets. These presumably worked well (I did not get sick as a result of poor water quality) but left an chlorine smell to the water and the bottle. The tabs did not affect taste once the water was in your mouth - the smell was not terribly pleasant, however.

A few items I did not extensively use and do not warrant reviews here - my neck gaiter, balaclava, insulated mitts and everything else.

Here's the whole list. It is not all quite accurate, notably the stove weight. I never did get a chance to weigh my fuel bottle without fuel in it.
