The "Most Difficult" via The "Most Interesting"

It was a three day weekend so I felt compelled to attempt a big mission in the mountains. Unfortunately the snow conditions were terrible and it was way too warm for ice. Sounds like late spring right? So instead of trying a real winter climb that probably wouldn't go, I decided to try a late season mountaineering route instead. A la Jeff Park Glacier on Mt. Jefferson, AKA the "most interesting route" on Oregon's "most difficult summit." Jeff Park Glacier is a big, crevassed glacier on Jefferson's north side that flows from the ridge between two impressive rock pinnacles. The route follows the glacier to this ridge and then traverses a knife edge of low fifth class rock to the north ridge and the base of the summit pinnacle.

I packed up the car and left Bend at noon on Saturday. The forest service road to the Whitewater Trail Head is mostly clear, thanks to the pitiful snow fall this winter. I was able to drive to within a mile of the trail head parking lot before my tires started spinning too much and I was forced to park. I left the car at 2pm, the road had good snow cover for skiing but the trail itself was mostly snow-less, forcing me to pack the skis. After the initial switch back section the snow reappeared and I was able to ski again. Once above Jeff Park (the hanging valley beneath the glacier) the snow became too icy for skins and I was forced to pack the skis again. I eventually made camp somewhere between 7000 and 7500 ft. in an icy depression. I fired up the stove and soon had plenty of water and a watery, warm bowl of curried rice and lentils. I crawled into my sleeping bag and turned the headlamp off at 8pm.

Sleep mostly evaded  me and I finally gave up and got up just after 3am. I melted 3 liters of water for the day and "cooked" some instant oatmeal with tepid water. After loading my pack and securing the tent with some big rocks, I started hiking at 4:30. There was a mostly full moon and I enjoyed hiking up the glacier without artificial light. Most of the crevasses were pretty well covered; I only punched through on one of them and it was obvious and small. The glacier has two bergschrunds, large crevasses caused by the glacier breaking away from snow pack above it. The first one was intimidating and took some time to get around in the dark, but I eventually located a good snow bridge. The second appeared more ominous, as there was tons of spindrift blasting over it, but in the end it was quite easy. I reached the top of the glacier at 6:15, 1:45 to climb ~2500 ft with some route finding issues. Not bad time, if I do say so myself.

The knife edge ridge traverse is called low fifth class rock climbing. I had read that there was a lot of exposure on it, and maybe it was scarier in the moonlight, but wow, big exposure is right. It was definitely an amazing perch; very narrow with several hundred feet of sheer drop on either side to steep snow slopes. The ridge crest also had a fair bit of snow and rime on it, so I ended up riding it horsey style quite a bit. This definitely made it the most awkward "rock" climbing I've done to date. The crux was a little tower on the ridge that was coated in rime ice. I climbed up just right of the crest and then had to down climb steep snow and rock on the back side. After the tower one more short horse ride led to the mellow north ridge. From there it was mostly walking, with only a short rime/rock down climb off a little nob, to reach the summit pinnacle.

Looking back on the knife edge ridge, leading to the snowier north ridge, from the summit. I didn't take any pictures before reaching the north ridge since it was dark.

By now the sun was peeking over the horizon and illuminating the east face. Being perhaps a little cocky I had thought that I would probably just reverse the whole route to descend, but I had no desire to hump my way back along the knife edge. The other descent option, which I hadn't really researched, was the East Face route. Now looking down the illuminated face I could see lots of very steep snow broken by cliff bands and getting warmed by the sun. This didn't look like a good idea either and given the extra time it would take to climb the summit pinnacle it would just get worse. I looked down the west side of the mountain at what I have since learned was the North Milk Creek Gully. This was still in the shade and I could see what appeared to be snow slopes, unbroken by rock bands, traversing around to the ridge above the Russel Glacier, a smaller, less steep ice field that parallels the Jeff Park Glacier. With this as my tentative descent plan I focused on the summit.

The north end of the summit pinnacle is a fourth class scramble in summer, now it was coated in thick, icy rime. Long lances of the stuff, upwards of three feet, had turned into solid ice blobs, probably as a function of the warm weather, and were sticking out of the snow at a downwards angle. Trying to find solid pick placements and move through them with a pack on was a slow process. There was only so much I was willing to bash off above me since the chunks were so large. I started by climbing a short chute to a hanging snow/ice field. From here I tried three different chutes leading up to the summit. I down climbed from part way up all three, feeling that they were too insecure and dangerous. I thought that maybe conditions just weren't good and that I would be denied after coming to within 30 vertical feet of the summit. However, I investigated one last gully, hidden around a corner to the far right. It looked doable, with some protruding rock holds, so I started up. I was able to traverse further right to the ridge crest and one final body length of rime climbing got me to the tiny summit (barely big enough for one person to sleep on). I took some photos, ate, drank, and admonished myself to descend carefully ("no mistakes, take your time"). The down climbing went smoothly and I was daggering backwards down the North Milk Creek Gully by 8:20.

The snow traverse over to the top of the Russel Glacier ended up being pretty continuous traversing on 40-45 degree snow. I crossed multiple gullies but only saw one ice chunk falling down. The last gully I climbed up instead of over to avoid steeper snow. This brought me to the ridge crest above the Russel, and to my relief I could see easy, walkable snow slopes all the way down. I may have even shouted with glee, knowing with certainty that the difficult parts were over and it was all clear sailing back to camp.

Sunshine! I could not have imagined better weather. The summit pinnacle is on the left.

Looking down the ridge line with the Russel Glacier on the right... easy walking at last!

I reached camp around 10am, just in time to see two other climbers descending from the Jeff Park Glacier, the first people I had seen since turning my car off the main road the day before. We stopped and chatted for a bit and I found out they were from Portland and had been camped just over the moiraine from me but we had never seen each other. They had also tried the Jeff Park Glacier route but turned around part way up the glacier due to crampon malfunctions. After they started hiking down I crawled into my sleeping bag and ate a snack. I briefly considered taking a nap but decided I'd rather get out of the cold shade of the mountain and down to that nice sunny weather I could see. I packed up and skied out without incident, returning to the car by 1:30. I stretched and ate a fresh apple on a sunny rock before driving home.

Amazing, rolling cloud formations above the Russel Glacier as I break camp.

Looking back at the mountain as it socks in with clouds during my ski out to the car... perfect timing.

Although this route was technically a couple notches easier than my Devil's Kitchen Headwall solo it was, in my opinion, a much harder climb. The constant accumulation of small, technical obstacles with big exposure, combined with the route finding issues and the uncertainty of whether or not it would go, made it a huge mental challenge. It also required a lot of my accumulated skill and experience to successfully navigate all the different parts of the climb. While the knife edge was definitely the technical crux, and the scariest section, the summit pinnacle provided the biggest challenge with its route finding. The most enjoyable part of the climb however, was the traverse over to the top of the Russel Glacier. Pushing an unknown descent path down an unknown (to me) part of the mountain was stressful but also very rewarding and I really enjoyed the sense of exploration. Finally, I'd like to thank some people, because a good solo effort is (ironically) only possible with the support of your partners... Edward, for taking me on those early mind expanding climbs and showing me what you can achieve with a level head. Travis, for being psyched to go climb in the alpine and first suggesting that Jeff Park might be soloable in winter. Lastly, Caitlin, for accepting, supporting, and trusting me not to do anything stupid. Thank you!
