Damn! We ended up climbing Jeff on June 3-4th and had a completely different experience. We went up Jefferson Park Glacier and found the knife edge ridge climb to be in AWFUL shape. Partially covered in rotten snow, it was very hard to protect and we had to move very slowly to get across. We got to the summit pinnacle, and it was much the same story. Really rotten, soft, shitty climbing snow.
I have a feeling we caught this peak at a really terrible time, but we super underestimated the technical challenges of this thing. Cool to see your trip went so well only 2 weeks back! Cool to see how much the mountain has changed in such a short period.
