Ascent Trip Report

I followed Bo Meng's GPS track, which is probably the best and easiest way to climb Price and Agassiz!

There is currently water along Bo's track as high as 9400 feet. There is a semi-permanent snowfield under Agassiz around 9600 feet that is probably the source of the water.

I doubt there is water above Lyons Lake during late summer or fall of a drought year. You might want to fill up at Lyon's Lake, or at the stream at elevation 8800 if you are unsure. This is a high snow year, though, so there was plenty of water.

Agassiz is not difficult. I'm not sure why people say it is. I assumed I was going the correct way up it, and ended up doing a single class 5 move up the South Side of the summit block. I assumed that was the normal way simply because people said that Agassiz is technically difficult. The Northside of Agassiz's summit block is actually easy class 3 more like class 2. The South Side is difficult. Agassiz is not technically difficult. If you made it up Price, you can make it up Agassiz.

Both Price and Agassiz had ammo box summit registers that are tethered to the summit block. Pyramid Peak had the same thing if I remember correctly.

Most of the climb above Lyons Lake is a solid class 2 with some class 3 moves here and there. I do not recommend climbing these mountains if there is a chance of rain, simply because there is a lot of climbing up steep granite slabs that would become very slippery. Definitely still possible, though.

I visited Lake Sylvia quickly on the way back down. I did not see any people while hiking today.

It took me 8.5 hours total, about 14.5 miles, and 4350 vertical.
