1967 Map of Monarch Peak

About this map

The San Andreas Rift Zone dominates the structural geography of this Central Coast landscape, cutting a visible path between Mustang Ridge and the Peachtree Valley. This 1967 field-checked survey reveals a sparsely populated ranching and agricultural corridor along the San Lorenzo Creek and Peachtree Road. The map provides specific locations for infrastructure supporting this rural economy, such as Water Tanks, Storage Bins, and a Gravel Pit. Notable landmarks include Austin Peak in the north and the Mustang Fire Control Station situated along the rift. To the south, the terrain becomes increasingly complex with numerous named drainage systems, including Tickner Canyon and Bryan Canyon, feeding into the broader Long Valley. This map is a precise record of the Monterey and San Benito county line as it traverses these ridges and alluvial valleys.
