Two photos from Heil Ranch Open Space, which is located outside of Longmont/Boulder up Left Hand Canyon. This place was nothing but pine trees and a sign that said mountain lion country. Supposedly there are sandstone ruins along one of the trails, so I'm going to have to go back with a topo map and a compass so I don't get lost.

The top photo is five images, one stop apart, combined in photomatix, edited in Camera Raw and CS3.

Bottom photo is three images, two stops apart.
