2015 Map of Oat Mountain

About this map

Santa Clarita and the northern edge of the Los Angeles basin meet in this topographic study of the Santa Susana Mountains. The terrain is defined by a complex network of canyons, including Towsley Canyon, Rice Canyon, and Sulphur Canyon, which historically served as critical transit corridors. Engineering feats are prominent here, with the Newhall Tunnel, Pacific Tunnel, and Santa Susana Tunnel marking the heavy investment in rail infrastructure required to penetrate the mountain barriers. In the southern half, the transition from wild terrain to suburban expansion is visible in neighborhoods like Granada Hills and Chatsworth, where the grid of streets like Rinaldi St and Devonshire St terminates abruptly against the rising slopes. Named landmarks such as Stony Point and Fern Ann Falls highlight the geological character of the region before it descends into the San Fernando Valley.
