It's tempting, when one visits Grand Canyon National Park, to focus attention on the mammoth hole in the ground (both for safety and for gawking purposes). This timelapse, though, makes a pretty good argument in favor of looking up.

The timelapse is the work of Gavin Heffernan (a.k.a. Sunchaser Pictures). The shots were taken at both Grand Canyon National Park and Monument Valley Navajo Tribal Park (which Heffernan reminds us may be familiar as the setting for Back To The Future III) and feature an almost surreally clear series of startrails, meteors, and an exceptionally gorgeous view of the Milky Way.
