Hokokam Star Party
Remnants of an ancient American Indian tribe, these petroglyphs sit atop a hill in the Saguaro National Park outside of Tucson. The Hohokam tribe existed there between 200 and 1400 AD. My girlfriend and I spent an evening there watching a meteor shower and making some long exposures over the Thanksgiving holiday. It remains unknown what the etchings mean, but I imagine it to be a representation of the earth spinning within the stars.
