Not so bad, just exposed.
Only 30 minutes or so from Sahale, but this was some of the worst rock I've climbed. Trip report.
Date may be wrong. Started at Sahale Campground. Traverse was simple scrambling with a touch of exposure, but I thought that the summit block itself was 5th class. It was vertical, the rock came apart in my hands, and I solo climbed with no gear or rock shoes and passed 3 permanent slings teams use to rope in on the way up and down, so I don't know why every comment calls it boring and easy. Maybe there are better ways up but I expected to die. Down was easier than up surprisingly. Plenty of places for feet and hand as its volcanic rock, but double check every one. The view OF Boston is better than the view FROM Boston, but I'm glad I did it.
You sure those slings weren't the rappel anchors? The climbing route is on the east side of the summit block while the rappel route is on the south side.
No where near as bad as I thought it would be. Very fun 4th class scramble actually. Did with Josh Lewis
The route quality was much better than I had expected it to be. Mostly class 3 with some class 4. A few loose spots that were not too bad. The views were fantastic, a bit of exposure, but over all a great peak. I would recommend this to a friend who was experienced.
Summited via Sahale Arm. Five hours to the summit from the Cascade Pass parking lot. The climb does not have much to recommend, except that you will be alone at the summit. The summit log is a huge aluminum box that has been there since 1966. The climb was mostly third class with one move of low fifth. Check your holds before using!
After spending a night on the Sahale - Boston col we summited Mount Buckner and the on the return summited Boston Peak via the East Ridge of the summit block. NIghtmarishly loose rock - a veritable bomb alley, but great views from the top of Forbidden, Eldorado, Sahale, Buckner, Glacier, Dome and Rainier. I only mention this summit to condemn it.
