Mariposa Peak and the surrounding heights of the Diablo Range define this high-relief landscape along the borders of Merced, Santa Clara, and San Benito counties. The area is characterized by steep canyons and prominent summits, including Cathedral Peak and Mt Ararat, which overlook a network of seasonal watercourses like San Luis Cr and Portuguese Cr. In the southern portion of the quadrangle, the terrain opens into the Quien Sabe Valley, a distinct geographical basin flanked by Saint Marys Peak and Laveaga Peak.
