The most popular photography spot in Arches National Park is Delicate Arch at sunset. (OK, so occasionally I go where the other photographers go, just not very often.) That day we really lucked out; it had been cloudy all day, but, just as the sun was hitting the horizon, it shown through a clear patch between the clouds and the horizon and gave the arch this amazing color. (No saturation boost on this photo; it really was that color!)
