Be sure and check out the excellent photos related to Horn Peak posted on the page linked to above. There are some nice photos from the peak itself as well as from several vantage points including the valley and other nearby peaks.

You can also find some good information on the Sangre de Cristo range and the other peaks at the following link. Be forewarned, you could end up getting sucked in and spending some significant time on this site!
