The boundary between Stanislaus County and Santa Clara County runs through this section of the Diablo Range, where a complex network of canyons and high ridges defines the terrain. The landscape is marked by prominent elevations such as Bear Mtn and Divide Ridge, which separate the headwaters of numerous seasonal and perennial streams. Water features are central to the geography here, including the namesake Mississippi Creek, as well as Coit Lake and Hoover Lake. The presence of Bear Springs and Board Springs indicates the importance of these water sources in an otherwise arid upland environment. Notable named landforms like Manzanita Point, Kelly Cabin Canyon, and Poverty Flat provide specific points of reference for local historians and land managers tracking the early usage and nomenclature of these interior coastal hills.
