Lucky me, I was xc skiing today AND had my pack with my camera and tripod with me. When I went around a corner into a draw, I could see across the draw (with a creek in the bottom) to the other side. There were a couple of groups of Mule Deer grazing between rock outcrops and, after watching for awhile, I spotted a mountain lion coming down the slope in-between a couple of groups of deer. It was aware of the deer, but never went after them. It made its way all the way down to the creek and at that point I lost sight of it. My lens was maxed at 300mm so no closeups but I am thrilled to have seen the lion today much less get a few photos.
