Not to be contrary, but this is most assuredly Sneffels as viewed from the bottom part of the trail into Blaine Basin from the Blue Lakes TH.
Hi Plugger, I'm about 5 years late on this comment, but I'd have to agree with Stryker... this is not Mt. Sneffels. This peak towers to the west of Blue Lakes... Mt. Sneffels would be out of site to the upper left of this photo from this spot.
