About this map

The Gabilan Range dominates this portion of the Central Coast, where the high-altitude divide between Monterey County and San Benito County follows a winding path through the peaks. This 2021 study shows a landscape of complex drainage systems and isolated valleys, most notably Grass Valley in the northeast and the centrally located Round Spring Valley. High points like Mt Harlan and Mt Olds provide significant landmarks for understanding the local topography.

Water sources are critical features in this arid upland terrain, with Horseshoe Spring and various creek systems like Pescadero Cr and Jacques-Hanlon Cr cutting deep canyons into the mountainside. The road network remains sparse, largely confined to the edges of the mountains, with Grass Valley Rd and Harlan Mountain Rd providing the primary access points into these high valleys and canyons like Caldwell Canyon.
