Short trip, but worth it for experienced riders. Must have a street-legal vehicle in the state park. Climb up to a WWII calcite mine and incredible views of Anza-Borrego State Park and the Salton Sea. Stay for awhile and explore numerous hiking trails and slot canyons.
Calcite Mine contained a high-quality colorless calcite that was used to make Norden bombsights during WWII. It was mined by digging trenches following calcite seams. You can see bits of the calcite when it reflects the sun. It is illegal to remove any plant, animal or mineral from the park.
