The document summarizes Mormon Rocks and Etiwanda Preserve. Mormon Rocks were named after Mormon Pioneers who camped there. The rocks were formed by the San Andreas fault lifting sandstone, which was then shaped by wind and rain erosion. The San Andreas fault runs through the area and holes in the Mormon rocks were formed as boulders moved out of the rock structures over time. The Etiwanda Preserve was created to protect the local Riversidian Alluvial sage scrub habitat and contains vegetation like white sage. It discusses the 2003 Grand Prix fire and includes a picture of a pocket mouse and kangaroo rat, two rare animals in the habitat.
