Cabazon Rock Plant #77
I drive on Interstate 10 between San Bernardino and Palm Springs, California on a regular basis. On the south side of the freeway near the Morongo Indian Reservation is a Robertson’s Ready Mix gravel pit (map)—Robertson’s calls it Cabazon Rock Plant #77. Some maps label the area “Cabazon” while other maps label it “Owl”.
Google Maps shows Matich Corp, a paving materials supplier, near the pit. I don’t know what their relationship is. Robertson’s address is 13990 Apache Trail and Matich’s address is 13984 Morongo Trail, both in Cabazon, CA 92230.
I’ve always liked the gravel pit and I’ve often thought of modeling it.
