Motte Rimrock Reserve
The Motte Rimrock Reserve, established in 1976, occupies a broad, rocky plateau on the western edge of the Perris Valley in southern California. Located equidistant between the climatological influences of the Pacific Ocean and Colorado Desert the Reserve supports an unusual mix of habitats.
Cultural History
The inland southern California area has been occupied by native American groups for thousands of years. Both the Cahuilla and Luiseño Indians probably used the Motte Rimrock Reserve land and surrounding areas as late as 200 years BP.
