2018 Map of Nattrass Valley

About this map

Nattrass Valley and the surrounding high country of the Diablo Range define this portion of Monterey County. The landscape is carved by deep drainages, including Wildhorse Canyon and Spring Canyon, which descend toward the seasonally flowing San Lorenzo Cr in the northeast. This 2018 survey reveals a terrain dominated by ranching and natural watersheds rather than dense urban development, where transit is restricted to narrow routes like Wildhorse Rd and Hamilton Canyon Rd. The distribution of named features like Peachtree Valley and Green Valley highlights the pockets of lower-elevation land where agriculture and settlement are most viable amidst the steep slopes. Genealogists and local historians can use these topographic details to pinpoint the family-named landmarks and rural roads that have served as the framework for life in this part of California for generations.
