About this map

The San Bernardino Base Line cuts through this high-elevation terrain in the late 1920s, anchoring a landscape defined by deep drainages and early canyon developments. The settlement of Calabasas Highlands sits central to the topography, while Brents Junction marks a key transition point in the northwestern corner. The placement of the Calabasas Sch provides a glimpse into the local infrastructure serving these foothill communities before the era of widespread suburban expansion.

Water sources such as Mohn Springs and the distinct geography of Red Rock Canyon and Stokes Canyon illustrate the natural constraints on early Los Angeles County habitation. The southern portion of the sheet highlights Topanga Park tucked into the headwaters of Topanga Canyon, showing the established mountain corridors that connected the inland valleys toward the coast. This record by the Board of Supervisors and the U.S. Geological Survey preserves the specific canyon-by-canyon development patterns of the region.
