1954 Map of San Gorgonio Mountain

About this map

San Gorgonio Mountain dominates this high-altitude landscape, anchoring the eastern reach of the San Bernardino range during the mid-1950s. The map illustrates a transitional period for the region, where seasonal recreation and hydroelectric development coexist with traditional resource extraction like the Mill Creek Mine. Along the northern edge, Big Bear Lake is shown with its developing shoreline communities, including Moonridge and Sugarloaf, while the southern slopes feature the established canyon settlements of Fallsvale and Valley of the Falls.
