2021 Map of Monarch Peak

About this map

Monarch Peak stands as a central landmark in this high-altitude section of the Diablo Range, where the boundary between San Benito and Monterey counties winds through complex ridgelines. The landscape is defined by its deep canyons and elevated basins, including Peachtree Valley and Long Valley, which follow the course of San Lorenzo Cr. Unlike more urbanized areas, the geography here is mapped by its natural relief and family-named landforms, suggesting a history of large-scale ranching and remote homesteading along the winding Peach Tree Rd. Notable rock formations like Cleveland Rock and Banchero Rock punctuate the ridges of Mustang Ridge, providing distinct navigational markers in a territory primarily organized by its watershed. The map records a network of drainage systems, from Lewis Cr in the north to the intricate tributary canyons like Tickner Canyon and Bryan Canyon in the south.
