Elderhostel “Photography in the Southwest” Workshop Day 1. Kelly Place & Canyon of the Ancients National Monument.

The first full day of an Elderhostel/Road Scholar photography workshop at Kelly Place — a Bed & Breakfast near Cortez, Colorado. I was attending the workshop with my Father and Brother. I went out on my own in the morning to take some pictures of Sleeping Ute mountain. After lunch walked around the site to look at some of the historical buildings and then went for a short hike into Canyon of the Ancients National Monument which is right next to Kelly’s Place. After it got dark, I set up a camera to take some star trail images.
