Shot in the summer of 2008, 25 miles north of Durango, Colorado in the Rocky Mountains. Specifically, these are the San Juan Mountains, in the Needles Mountains subrange.

Facing eastward as the sun sets, note Twilight Peak (13,158 ft.). Flanking either side are sister peaks, North Twilight Peak (13,064 ft.) and South Twilight Peak (13,097 ft.) In the foreground, covered mostly by alpine trees, is Potato Hill (11,850 ft.). A thunderstorm has just past through the region, and a rainbow is prominent in a few clips.

All of these clips were shot with either the Sony HDR-SR12 or HDR-TG1. Unfortunately, I can't remember which clips, in particular. Also, you'll notice some movement from time-to-time in the later clips, as the TG1 is so lightweight, that any movement around the camera was picked up in the timelapse.
