Very nice mountain, it has it all. Nice trail through forest, meadows, alpine basins. Beautiful lake and xc up to short but steep snowy headwall. Craggy summit block with awesome views of jagged Sawtooth range. View S is blocked a little by neighbor Mickeys Spire. Boot axe belayed my unconfident partner with a small rope coming down the headwall.
I mistakenly took the southwest route thinking it was the wide gully I needed to be in. Almost backed out when I saw the 5.2 with the exposure on both sides. I found the South Couloir after I reached the summit. Duh.... Beautiful area. Did Borah Peak on the 12th so this was a great topping.
Very beautiful area. Lakes, snowfields, and pointed peaks galore. Lots of fish to be caught in the lake at the eastern base of the peak. Expect a class 2 hike to the top with maybe a class 3 move or two at the top. There are several other peaks to be bagged nearby like Mickey's Spire and Mount Carter.
This was my first major summit ever accomplished, and now looking back, it probably wasnt the best choice for my first. However, besides the long approach, Thompson Peak offers beautiful views, glacial lakes, and a complete wilderness experience. A truly enjoyable mountain..
PS.. an ice ax and ropes are a must if attempting to summit early in the summer, I sure needed em.
