Progression of colors during sunset at 14000+ high elevation. The first view was about 25 minutes before the second and 35 before the third. Sun went behind the mountains a few minutes later.
We are looking at the Mount Sneffels, which is something like 18 miles away, while standing on the Handies Peak. Both are Colorado 14ers. Based on the angle in the third view, looks like I started my descent after taking the first two. It got pitch dark pretty soon after that.
