good climb to Boundary Peak today, brought too many clothes only needed a base layer and a light jacket. No microspikes/axe needed. 3L water is enought. Met two highpointers from Reno, NV and we hiked back together.
There is a clear trail so just follow it into the bowl and climb to your right and you'll be fine, I used an old map and went off trail, the hardest part is to gain the ridge, very steep, seems forever! But after that it's just 1.5hr to the top and you can see it. I'd recommend an SUV to drive to the trailhead, there are 3 tricky spots for sedan (but the other two guys took an older Subaru Outback and made it no problem).
The 'scree' was ok, not too bad compared to Granite, the difficulty is probably behind a very windy Mt. Elbert. Total time is 7.5hr with about 1hr probably wasted.
