1903 Map of San Antonio

USGS Topo · Published 1916

About this map

The San Antonio Mountains dominate this early 20th-century landscape, showing the sharp transition from the Mohave Desert to the high elevations of the Angelles National Forest. This era predates modern infrastructure, focusing on the topographic relief of the eastern San Gabriel range. Prominent peaks such as San Antonio Peak (Baldy) and Telegraph Peak are mapped alongside the treacherous Devils Backbone. The drainage patterns of Lytle Creek and the Prairie Fork reveal the deep canyons and narrow passes that defined early transit through the region. At The Narrows and along Lone Pine Canyon, the map captures the geological severity of the area before extensive development. Remote drainage points like Mine Gulch and Vincent Gulch hint at the prospecting and early resource exploration that drew settlers into these steep, water-carved ravines.
