Valles Caldera National Preserve
National Preserve — NM
About 1.2 million years ago, a spectacular volcanic eruption created a 14-mile-wide circular depression in the earth now known as Valles Caldera. The preserve is known for its huge mountain meadows, abundant wildlife, and meandering streams. The area also preserves the homeland of ancestral native peoples and embraces a rich ranching history.
