The future of carrying heavy loads?

I haven't seen my idea for helium-filled backpack bladders take off, but here's something really different, thanks to those MIT engineers:

Maybe it's an outreach program for cyborgs? Extra nerd points for you if you knew there was an International Journal for Humanoid Robotics. And, does this qualify as aid climbing? Can they make it less Gumpish?

Mt. Adams, Mazama Glacier

Tacoma Mountaineers, Basic Glacier Climb (July 27-29, 2007)

Having been weathered off the same route in 2005, I conservatively planned a 3-day trip, with either a weather contingency or an option for a more casual pace. We didn't need the former, and opted for the latter, giving us plenty of time to look around, take pictures, and enjoy ourselves, especially while we had the Mazama route to ourselves.




The Adams Team: Dave, Jessica, Katie, Brian, Mark, Don, Sherene (missing are Jim and Mindy)

We drove through Trout Lake and the Yakima Indian Reservation to the Bird Creek Meadows trailhead. We opted for the shorter climbers trail nearer to the ridge then wandered through the braided boot paths up to the moraine. Last time we went up and over the low point on the moraine at the high point of the vegetation, but this time we went down and around the base of the moraine-- a mistake. Don't follow this boot path, even though it looks do-able. Took us maybe an extra 30 minutes to scramble up the loose rubble to the terrace where the other route traverses to base camp. To locate best path, go up to the bootpaths to the moraine, then look for where the small trees/shrubs are highest in a triangular pattern. There is a zigzag path just above and behind that toward a saddle on the moraine.


Crossing the moraine

From the top of the moraine, go uphill about 50 m then traverse across the other side of the moraine toward the flatter terrace. Pass the ice-filled lake and continue across a few meltwater streams, roughly at the same altitude. Cross a few snowfields on an ascending traverse, then climb up the short rocky section next to the stream near Sunrise Camp. On approach, we took about 3.5 hours, with lots of photo stops. On descent, we took maybe 2 hours. There were a few patches of snow closer to Sunrise Camp.



Sunrise camp

Sunrise camp was completely melted out, and I was surprised at how far up the rocks we had to walk before we hit the glacier to rope up-- much less snow than in 2005 (a very low snow year but climb was two weeks earlier) when snow was right at Sunrise Camp. Lots of running water-- very silty. Brought coffee filters to pre-filter glacial silt. Very windy/dusty camp in our Megamid! We spent a second night there instead of walking out due to tired students with blistered feet. Much better in the morning! There were several other parties in camp, but they were friendly. By the way, the Adams/forest service scat packs are not even close to gas impermeable-- I'd recommend bringing your own blue bags to avoid that fun poopy pants smell! Yeah, you know the one....

The lower glacier was in great shape! We considered going straight up on the far right, between the crevasses and rock ridge, but the hundreds of small divots in the snow suggested rockfall hazard (we didn't see or hear any while in camp, though).



Mazama Glacier, Mt. Adams, July 2007


On the flats above the first glacier section, we traversed to the left, crossed a small bergschrund, and took the South Spur route from there. The alternative, across the glacier/snowfield to the right, crossed a rockfall area and open crevasses, and we weren't going fast enough to be safe.



Sherene and Mark, roping up early morning

We took a rising traverse left toward the center of the glacier, keeping the smaller crevasses to climber's right, then found a great flattish ramp below the top-most crevasse that runs nearly the entire width of the glacier where we zagged back right toward the rock ridge. Because the snow was hard and ice axe arrest impossible before the next downhill crevasse, we did a running belay with three pickets driven into the very hard snow to get by that short section. Where the glacier flattens above that we considered two exits from the glacier. The "normal" route continues right up another glacier remnant, then exits leftish into the scree/talus. It looks steeper from a distance than it really is, but there was a good portion where the snow had melted out to the glacial ice underneath. However, the rock ridge that splits the right and left lobes of the glacier was melted out and lots of rocks littered the top of the glacier. With a slow pace and fully opened icy crevasses to cover, I was uncomfortable with the objective danger. Instead, we traversed left on the flattish section of glacier to where it steepened, then skirted a bergschrund on climber's left to reach the rock ridge around 10,500 ft, at a rock formation now fondly called the Scottie Dog (at least by us), crossing a short (30 ft) scree slope. We marked our ridge crossing with a wand, unroped and left our glacier gear, then took a diagonal ascent over snow and scree to meet up with the south climb around 10,800 ft or so.

There were hordes on the South Spur. The route was mostly snow covered, with a few rocky bits at the false summit and up the final climb. Pretty deep glissade chutes off the false summit. Everyone dashed their crampons and glissaded back to the point where our route went east from the south climb. Crampons balled up on the way down, but there were a few icy patches to contend with. Same running belay on descent through the crevasses on the lower glacier. We roped up at 5:00 and exited the glacier around 7:30. Climbers summited between 11:40 and 12:15 after we re-grouped at the false summit. Descent was quicker-- 3.5 hours back to camp.

I recommend the 3-day option, especially with the combination of a long drive and opportunity for bad weather. Very fun group of people!

Lassen, Shasta, and Thielsen

We had planned a climb of Mt. Challenger for July 2007, several months in the making with a great team of people. Conservatively, we had an 8-day window for a 4-day climb. But we were cursed by the summer that wasn't. Summer 2007 hopefully is an anomaly. The rain just didn't quit. The latest forecast was for a storm to descend on the region and stay, eliminating any chance of climbing from British Columbia, through Washington, and south as far as Crater Lake. To get anything done, we had to go south. Way south.

Outrunning the rain, southbound on I-5

Depressed that our premier climb for the summer was now toast, we drove to California and started climbing volcanoes. We drove to Redding in about 8 hours, with an infamous stop at the Eugene, OR, Fred Meyer store. Steve needed to unwind after battling rain and traffic-- who knew Fred Meyer could be so entertaining as we watched people's expressions as they watched Steve?


Steve, chillin' at Fred Meyer

We figured we'd need a map, and we unwisely chose a bookstore in Redding, CA, the night that the latest Harry Potter book was being released. The store was swarming with Muggles, but there were no maps in sight. Oh well, how bad could it be to get up Lassen? We didn't even know what to expect, but we thought it was a walk-up.


Approach to Mt. Lassen

There had been talk of just driving right to Lassen and doing a midnight climb, but it didn't sound that good after driving so long. We opted for an early-morning hike to beat the crowds. We didn't need a map to follow the switchbacks either. Just to make things interesting, we did an off-route exposed scramble near the top that we didn't need to do. The weather was mild and the wind was calm, and the sun was out. Not a cloud in the sky, and that was the point.

Next we thought we'd better get a map for Shasta. I had done some online searches and found only one route even reasonably passable-- the Hotlun-Winton route on the north side of the mountain. This avoids the crowds and infamous rockfall of the Avalanche Gulch route, which was way out of shape but still ridiculously crowded.

We weren't sure where to find the ranger station, so we checked with an incredibly unhelpful USFS office outside Redding, where the ranger was clearly pissed off that we dared to show any local knowledge of the route at all. Fortunately, we found a very helpful (and correct) ranger at the Mt. Shasta ranger station, who showed us recent photos of the route and was glad we weren't following the crowds up Avalanche Gulch.

The approach was a little warm, but we were still enjoying the sun. We walked up a very circuitous trail toward a scree field, then followed various bootpaths up to a good spot on the ridge for a base camp. It took awhile, but we found a reasonably flat place somewhat sheltered from the wind and near running water.



Mt. Shasta north side trailhead

We got up around 4:00 and took off at 5:00, carrying ice axes, helmets, ropes, harnesses, pickets and wearing crampons, but it turned out we didn't need the ropes or harnesses. The snow slope was pretty easy going, then we crossed over the rock ridge to the left and traversed a reasonably steep snowslope to lead to the upper glaciers/snowfields. A boulder dislodged from the rocky slopes above and tumbled down the snow-- just a reminder that the route wasn't entirely without rockfall. But it was the only rockfall we saw on that side at all.

Snowslopes above base camp. Route followed right snowfield up to flat part of rocky ridge, then crossed left onto other snowfield/glacier. Steepest snow right below summit.


Traversing snowfield/glacier after crossing rocky ridge

We took turns kicking steps up the steepening snow, taking a steady pace above 12,000 ft. There had been recent snow on top of the ice that had bonded well, so we decided not to rope up at all. The last few pitches were maybe 50 degrees, but the steps were holding well.

We hadn't seen another person up to this point, but then we joined the south side climbers for the last traverse to the rocky summit block. There were only maybe 8 other people, but I would have preferred zero. They weren't bad-- I just didn't trust people who chose to ascend Avalanche Gulch that late in the season.

The view was outstanding! We could see up the line of the Oregon volcanoes on a very clear day. After a few summit shots, we descended back to our base camp around 10,000 ft, took an hour to rest, eat, and hydrate, then headed back to the trailhead.

Mt. Shasta, from north side

At a restaurant in the funky town of Mt. Shasta, we asked our waitress the closest place we could camp and grab a shower, and she pointed us a few miles out of town. Our beers were on the house since we had summited Shasta-- sweet! We got to camp in time to shower and crash as darkness descended.

The next day we put on our tourist hats and drove through Crater Lake. What an amazing shade of turquoise! The place was an absolutely zoo full of people from all over the world. Off in the distance, across Wizard Island, we spotted our next objective.

Mt. Thielsen has a very pointy summit. It looks like the sorting hat from Hogwart's. Unfortunately, some clouds had moved in an partially obscured the summit at times. Thunderstorms aren't unusual.

Mt. Thielsen. Route follows right skyline.

We left the trailhead for Mt. Thiesen at the crack of 2 p.m., like good peakbaggers. The trail wound up to the Pacific Crest Trail, crossed it, then continued up along the loose talus ridge. At that point, Julie's blisters wouldn't let her continue, so she headed back to the car to scope a camp site. We had a map, but the trail had been relocated from what was shown. Oh well, fortunately navigation was easy-- follow the ridge and don't fall off.

We helmeted up for a short scramble section to the base of the final summit pyramid. Chuck belayed Steve up about 20 meters of low-fifth-class rock. While Steve was setting up the anchor, the clouds rolled in again, so by the time Chuck and I got to the summit, we couldn't see a thing. Oh well. We took our cloud-enshrouded summit photo anyway, then signed the summit register. Since Thielsen is popular with thunderbolts, we rappelled off and scrambled down quickly.

Descending loose stuff on Mt. Thielsen

We were pretty pooped after three summits in three days. We boldly considered climbing Mt. Bachelor on the way back, but that was a little ambitious. We did scout The Sisters and McLoughlin, though, with plans to return next year.

The sunshine was a welcome break, but the gray curtain descended as we crested a pass in the Oregon Cascades. Fun road trip with great adventures!

Mt. Maude, Entiat Icefall Attempt

On September 1-3, 2007, four of us (Lisa, Julie, Jim, and Mindy) attempted to climb the Entiat Icefall on Mt. Maude. A trip report from three weeks prior had raved about great conditions, 2-3 pitches of belayed climbing up to 60 degrees, and good stances for placing ice screws and building anchors. Ideal! The original plan was to climb the Lyman Glacier on Mt. Chiwawa, but poking around on the web, it looks like the Lyman Glacier has melted away to nothing, eliminating one of the best introductory alpine ice climbs in the Cascades. Julie wanted an ice climb, and the Entiat Icefall seemed like the best option to actually climb ice.

We parked at the Phelps Creek trailhead only to find at least 60 cars ahead of us. What a zoo! Fortunately, after walking 3-4 miles along the flat riverbed, we hung a right at the Leroy Creek basin climbers trail, and climbed up into the high basin to camp. There were a few tents there, but probably nowhere close to the mob scene at Spider Meadows, which would have been our approach if we stuck with climbing Chiwawa. The first 1000 ft up are pretty steep, but the grade leveled off into Leroy Basin. We were reasonably fast going to base camp (3 hours).

This was Lisa's first outing since her heel healed, so she and Jim hung out in base camp while Julie and I scouted the approach that we would follow in the dark the next morning. The climbers trail was a pretty good boot path until the talus fields, then we started following cairns. A woman at the trailhead had warned us about a deep gulley that was a pain to get into and out of, and that gulley became quite obvious as we got close to it. Supposedly it's been there for a few years, but it still looks fresh. We found the best booth slide down and up the other side, but it would not be fun to do in the dark.

Seven-Fingered Jack from Leroy Creek Basin

Expecting a 14-hour day, we got up at 4:00 and left at 5:00 a.m., following our newly rebuilt cairns across the talus to the gulley. Yes, it was a pain. The talus continued up to the south end of Leroy basin at 6800 ft, then we continued up the shoulder to the col with the Ice Lakes basin. By this time it was light, and we could see the clouds already starting to build. Having been skunked by the weather all summer and having cowered from thunder and hailstorms in the Tetons and City of Rocks recently, I wasn't pleased. Plus, I was feeling not quite up to par thanks to some stomach bug.

Fortunately, the 7600-ft traverse across the bench was easy to spot from the col. Unfortunately, there was very little snow left on it. Sidehilling a somewhat-steep slope covered with talus takes a lot of time and concentration. Snow is much better. But we continued to traverse above upper Ice Lake toward Marmot Pyramid. It took us longer than expected, though, thanks to the loose conditions. We reached the top of the South Entiat Glacier by about 10:00 (5 hours).

Looking at the headwaters of the Entiat River, then looking at the topographic map, it's clear that things have changed. Drastically. There are several glaciers shown in the cirque below Maude, Seven-Fingered Jack, and Fernow that simply don't exist or are very small remnants of their former selves. I guess one advantage to doing this trip so late in the season is that it's easy to distinguish snowfields from glacier. And now it's mostly snowfields that melt out each year.

Mindy and Julie survey the scene.

We decided to rope up and head down the South Entiat Glacier 800 ft to the base of the Entiat Icefall, as in the trip description. But we stopped at some rocks showing near the current base of the South Entiat Glacier, looking at the snout of the glacier. No wonder the original description calls for nine pitches-- it used to start way down there! At least three pitches have melted out completely. Instead of walking down the South Entiat to the base of the climb, you now have to hug the south wall of the Marmot Pyramid and look for a boulder to rappel off of to the start of the climb.

We never got a clear view of the entire icefall, but the base of it is no longer snow covered ice-- it's ice. Plus, there was new icefall debris at the base of the icefall (huh, maybe that's why they call it an ice-fall!). We had plenty of time, but with a series of yellow lights, we decided to turn around. I wasn't feeling great, Lisa wasn't sure she was up for a full 14-hour climb, the clouds were threatening, conditions had deteriorated on the icefall, and I wasn't convinced our party could move fast enough in case the weather got worse. Darn. The curse of Summer 2007.


Heading back up the South Entiat Glacier after turning around. Weather looked momentarily clear!

Maude is a very worthy objective, and I'd like to return to climb the icefall, but aiming for mid-August. Even though it was climbed over Labor Day weekend in 2000, the conditions this late in the season in 2007 just won't work (except maybe in high snow years). This was a pretty normal snow year in many areas. It's a spectacular setting, with views of Fernow, Bonanza, Seven-Fingered Jack, Glacier Peak, Buck Mountain, and Sloan and Rainier off in the distance.

The return to base camp was uneventful, and we lingered an hour at the 6800-ft col playing name that mountain. Well, Jim and Julie speculated a bunch, but then we started taking bearings to be sure. The huckleberries were ripe, and we saw lots of marmot, a few pika, a deer, and a marten-like critter. We decided to just spend the night again and hike out in the morning. I was unsuccessful in my attempt to start a game of charades, even though a had a killer first round with "sounds like Fountain Mouse." There were a few mosquitoes and black flies, but not bad at all even for a somewhat wet area. Water was still running in a few arms of the stream, even though all the snow was gone from Leroy Basin.

Turns out there were several other buddies of ours from the Mountaineers in the area. We ran into Steve Kleine and his wife and daughter hiking out from Spider Meadows as we were going in. John Wickham and Ron Lavigne passed us in Leroy Basin on their way in and out on a Fernow adventure. And Dan Lauren's climbing team beat us out on Monday morning on their way back from Fernow. When we got home, we found out Chuck Robinson had been on Dumbell Mountain-- all from the same trailhead. Small world.

Crack climbing at Royal Columns, Tieton

We had a great opportunity to learn the fine points of crack climbing from Jens at Max on September 8 and 9 at Royal Columns in the Tieton River area. On Saturday and Sunday, six of us each day (Jayson, Brian, Susan, Eric, Jim, and Mindy on Saturday, then Lisa, Chuck, Julie, Dale, Jim, and Mindy on Sunday) went from instructors to instructees. Among other things, we learned simple taping to protect our hands... kind of. We still had scabs afterwards.





Jens demonstrated everything from thin fingers to ring locks to cupped hands to hand jams, but let us discover useful things like arm bars on the wider cracks.




Then it was up to us to use the stuff and figure out how it works. Over the two days, we climbed a bunch of routes ranging from 5.4 to 5.10c, focusing in the 5.7 to 5.8 range.



On Saturday I was a little surprised to get near the top of Mushmaker only to get rattled at by a rattlesnake that was less than a foot from my hand on a ledge. Susan was a little puzzled when I pushed off the rock, said "Lower," then said "... faster!" It was about 4 ft long and about 1.5 inches in diameter, coiled up, and seriously ticked off at being disturbed! The next climbers didn't bother going all the way to the top of that climb. A little later, I peaked over the top of the next crack over (one of those fun, uncomfortably-wide-but-not-quite-off-width) to see if the snake had disappeared, only to find it stretched out lengthwise with its head toward the rope, slowly recoiling its head. "Lower!"

Brian didn't believe me (?!) but discovered the snake now a little bit down on the climb in a recess that was recently used for hand jams. The next day, we found the snake even further down INSIDE THE CRACK we had been using. Check where you put your hands when climbing at Royal Columns....

Both days ended when the feet and hands gave up, sore and a little bloodied.




We're hooked!
