1978 Map of Fort Ross

USGS Topo · Published 1985

About this map

Fort Ross State Historic Park anchors the coastal corner of this survey, preserving the legacy of the Russian-era outpost on the Sonoma coast. The landscape is defined by the massive San Andreas Fault Zone, which carves a distinct northwest-southeast trench through the terrain, separating the coastal bluffs of Fort Ross from the interior ridges. Inland, the map reveals a remote network of family-named landmarks and ridge-top features like Marshall Ridge and Mohrhardt Ridge.
