2012 Map of Isabel Valley
USGS Topo · Published 2012About this map
Martys Ranch and the headwaters of Isabel Cr define the high country of Santa Clara County in this modern survey. The landscape is characterized by prominent peaks and deep drainage basins, where water flows from heights like Mount Isabel and Sugarloaf Mountain into the complex creek systems of Arroyo Bayo and Middle Fork Coyote Cr. The area’s geography is marked by isolated landmarks and named ridges, including Castle Ridge and Jays Ridge, which overlook the broad Isabel Valley. The sparsely developed terrain is accessed via narrow routes such as Graveyard Rd, following a pattern of land use centered on ranching and watershed preservation. Notable features like Indian Springs and Pyramid Rock serve as essential local navigational markers within this complex network of canyons and flats.
