There is painted beauty hidden deep in the heart of Riverside County. I had to go see this for myself because I don't normally associate Riverside with the word "beauty".
This site is located in a spring fed gulch amid a moat of fancy horse properties. Scrubby oak trees and tall stands of cat tails frame the tepid stream from the spring. A scattering of granitic boulders and several larger formations dot the slopes on each side of the spring. One such formation is a collection of ground level boulders crowned by two large capstones, and beneath these are two very colorful panels of polychrome art.
Large circles or shields accompany a number of crosshatch designs. Several elements here appear (at least to me) to have a celestial connotation. The work is bright and colorful, rendered in red, white, and a blue/black.
On the opposite side of the creek is a flat granite slab with four bedrock mortars. This slab, just feet from the spring, has been described as a "birthing rock. A short pillar beside the the slab has two faded red pictographs of diamond chains on golden water streaks. A short distance away is an additional BRM.
I was impressed with this site. The colors remain bright and crisp. Obviously any site with a consistent water source would have been an invaluable commodity in this desert region, and the depth and development of the BRMs speak it's prolonged use.
