About this map

The high ridges of the Diablo Range dominate this portion of Fresno and San Benito counties, defined by complex topography and intermittent watercourses. Cerro Colorado stands as a prominent peak overlooking the intersection of several distinct drainage basins, including the headwaters of Mercey Cr and its southern fork. The landscape is marked by tucked-away lowland pockets like Slacks Valley and Little Panoche Valley, which historically served as vital corridors for movement through this arid upland. A unique geological profile is highlighted by the presence of Glaucophane Ridge on the eastern edge of the survey area.

Transportation in this remote sector relies on winding routes such as Panoche Rd and Vasquez Creek Rd, which navigate the steep descent into Las Aguilas Canyon. The map records the convergence of multiple county lines, showing where Fresno, San Benito, and Merced counties meet amidst the rugged terrain. These boundaries often follow natural divides, such as those separating the watersheds of Vasquez Cr and Las Aguilas Cr.
