Hike
Calcite Mine Area, Anza-Borrego Desert State Park, California
View Original Description
The Calcite Mine Trail is located in Anza-Borrego Desert State Park, California. There is a 4-mile long old mining road which was newly graded in winter 2025 into the Santa Rosa Mountains to a parking spot. It’s still quite winding & steep, but a fairly easy trek.
Once there there are several narrow ravine with slot canyons that hikers may explore.
During World War Two the area was heavily mined for its high-grade calcite, a mineral then used to make bomb sights.
