About this map

San Juan Creek carves a wide path through the eastern reaches of San Luis Obispo County, defining the agricultural and ranching corridor of the San Juan Valley. This 1961 survey, updated with late-20th-century aerial data, captures a landscape dominated by the complex drainage systems of the Temblor Range and the Red Hills. The land use is primarily pastoral, centered around sites like Canyon Ranch and several rural infrastructure points including a remote Landing Strip and a network of unimproved dirt roads accessing the deep interior canyons.

The topography is characterized by dozens of named canyons, such as Tucker Canyon, Gillis Canyon, and McDonald Canyon, which feed into the primary creek beds. The drainage patterns and the alignment of Truesdale Road and Shell Creek Road reflect the geological orientation of the coastal ranges. This map provides a detailed view of the water resources and land divisions in a sparsely populated region of California, where numerous wells support the cattle and dry-land operations typical of the era.
