The San Gorgonio Pass serves as the focal point for this wartime survey, showing the critical corridor where the Southern Pacific railroad and major highways, including 60 and 99, navigate the gap between the San Jacinto Mountains and the northern ranges. The map documents the established ranching and resort culture of the early 1940s, featuring the Highland Springs Resort and Gilman Hot Springs, alongside the agricultural hubs of San Jacinto and Hemet. Significant portions of the landscape are dedicated to the Morongo Indian Reservation and Soboba Indian Reservation, which include landmarks such as the St Boniface Indian Sch. In the higher elevations of the San Bernardino National Forest, the map details a network of fire lookouts and guard stations, including the Barton Lookout and Millard Canyon Guard Station, reflecting the importance of forest management and watershed protection in this arid region.
