Mormon Rocks were formed 30 million years ago by tectonic tilting. Located in the North Etiwanda Preserve in San Bernardino County, the rocks exhibit sedimentary cross bedding and natural holes formed by weathering. The 1200 acre preserve protects local plant and animal habitats and features impacts from fires, earthquakes, and human water systems.
