About this map

Salton Sea dominates the southern landscape of this 1958 survey, where the arid basin meets the northern reaches of the Salton Sea State Park. The shoreline is marked by the small outpost of Desert Beach and a Boat Landing, situated below the tracks of the Southern Pacific railroad. To the north, the Mecca Hills rise sharply, dissected by complex drainage systems like Painted Canyon, Box Canyon Wash, and the deep recesses of The Grotto.

Evidence of desert life and infrastructure is found at Shavers Well and the Sheep Hole Oasis, while the Coachella Canal snakes across the desert floor, providing vital water to the region. Much of the western territory is designated as the Torres Martinez Indian Res, reflecting the tribal lands that intersect this desert expanse. The map also captures several industrial and remote features, including a Gravel Pit near the reservation boundary and the secluded Hidden Spring.
