Ascent Trip Report

Summary: The 2,000-foot boulder-field leading to the summit seemed endless. I found it difficult and mentally exhausting. Came across enough unstable rocks that nothing could be trusted. Even worse, the sharp rocks shredded my favorite gloves! The usual climbing chutes still held snow, reducing the route options. And avoiding the abundant sky pilot was very challenging (a good problem to have!).

Climbing notes: After reaching Bishop Pass in a little over three hours, I started up Agassiz's west slope and then moved left into the far-right chute of the northwest slope. In retrospect, on the way up I got too high on the mountain before dropping into the chute. This led to some uncomfortable class 3 climbing before I was able to regain the correct route.

Coming down, I did better navigation-ally, but all the loose rubble and rocks made for very slow going. I was feeling the elevation too and at times my pace slowed, literally, to a crawl. In the end, I clocked in at an epic (headlamp required) 14h45, perhaps the most time I've ever spent on a dayhike.

About 13.5 miles and 4,400 feet of gain.
