Short paved-access interpretive loop in Anza-Borrego Desert State Park along Highway 78 that explains some of the park’s oldest exposed rock, faulting, and desert canyon geology. Designed as a roadside earth-science stop with numbered markers—an easy field geology pin distinct from the longer canyon and badlands routes deeper in the park.
