Valles Caldera

Valles Caldera is a 12 mile wide collapsed volcano in the Jemez Mountains near Los Alamos, NM, which is owned by the federal government as a National Preserve. It was formed by a series of volcanic eruptions about one million years ago. It is used to feed cattle in the summer, and elk come there to graze all year long.
