Simi Valley is shown here during a period of sustained suburban development, characterized by a grid of residential streets that meet the canyon-riven slopes of the Simi Hills. The transition from urbanized floor to the high ground of Big Mtn and Rocky Peak is punctuated by a dense network of utility and fire roads, such as the Salt Creek Fire Rd and Middle Ridge Fire Rd. This interface between human settlement and the steep topography of the Transverse Ranges is a defining feature of the area's geography.
