2012 Map of Monarch Peak

About this map

San Lorenzo Cr defines the central drainage of this landscape in the southern Diablo Range, winding through a terrain dominated by significant elevations and named peaks. The map details the prominence of Monarch Peak and the nearby Mustang Ridge, alongside distinct geological features such as Banchero Rock and Cleveland Rock. This area, characterized by its drainages and ridges, shows a network of canyons including Griswold Canyon, Blair Canyon, and Tickner Canyon that cut through the high ground. Human activity is represented by the path of Peach Tree Rd and Pine Valley Rd, providing access to this interior coastal range. The cartography illustrates a transition from the lower elevations of Cow Cr and Lewis Cr to the heights of Austin Peak and Chalk Peak, mapping the drainage patterns essential to the local watershed.
