This is not Dallas Peak, just an unnamed 13er-but a gorgeous one for sure (really rotten, too).
Thanks for the clarification. A few people on flickr.com had pictures with labels stating this was Dallas Peak, even though it seemed a bit too far to the east of Mount Sneffels.
Actually the mountain is to the west of Sneffels. Dallas Peak is just southwest of Sneffels. It's no doubt in some of your photos from the summit. It's directly south and right above Blue Lakes. Looks like you had a nice trip in Colorado!
