San Bernardino National Forest encompasses this high-elevation landscape, where the transition from desert-facing slopes to the alpine basins of Bear Valley reveals a history of extraction and high-altitude settlement. The map centers on the dry expanse of Baldwin Lake and the developing community of Big Bear City, which by the late 20th century shows significant expansion around the Big Bear City Airport and Sugarloaf.
