Contrails from Wasson Peak

Ok...abandonning the daily numbering in titles for a while. I'm, obviously, not so good at updating daily, so numbers are going by the wayside. But, enough on that - you're here for photos, not explanations :)
Today's photo is from January, 2008. I was hiking to the top of Wasson Peak with a friend and we were doing our best to reach the summit before the sun set. Parks of the trail were in deep shadow, and others were glowing with saturated light. I happened to look over my shoulder and catch this great silhouette of mountain rock and blue sky. When I was little, my mom and I used to have fun scanning the winter sky for contrails, and I've always gotten a little thrill out of spotting one.
