Industrial activity and protected landscapes meet in the Santa Ana Mountains as documented in this late-1960s survey with late-1980s revisions. The map details the extraction history of the region, specifically marking the Santiago Coal Mine and Black Star Coal Mine, along with the Claymont Clay Mine further north. These operations are situated among the deep drainages of Black Star Canyon and Fremont Canyon, which feed toward the Santiago Reservoir.
