The Milky Way appears over a bizarre geological formation (called Panaca formation) in Cathedral Gorge State Park, Nevada. Click on the second photo to see another nightscape view of the canyon. This place was covered by a lake nearly a million years ago. The richly colored canyons are remnants of this ancient lakebed. Over centuries the lake began to gradually drain. Erosion on the exposed parts of sediment and gravel carved rivulets, splitting tiny cracks and fissures into larger and larger gullies and canyons.
