USGS Topo · Published 1956

About this map

Opal Mountain and the surrounding high desert of San Bernardino County are depicted here in the mid-1950s, revealing a landscape defined by isolated ranching outposts and ancient geologic formations. The map highlights the scientific and historical significance of the region, specifically around the Fossil Beds and Rainbow Basin, where the terrain drops into Fossil Canyon and Coon Canyon. Evidence of early human activity is captured through markers for Petroglyphs and the aptly named Inscription Canyon, located near Scouts Cove.
