Valles Caldera National Preserve

San Antonio Cabin often housed cowboys when the preserve was privately-owned and operating as a ranch.
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.
