2012 Map of Collins Valley

About this map

Collins Valley serves as a central corridor for the seasonal drainage of Coyote Cr, defining a landscape where desert hydrology dictates the location of early settlements and water sources. In this 2012 depiction of San Diego County, the reliance on desert riparian zones is evident through named groves such as Middle Willows and Lower Willows, which stand in contrast to the arid reaches of White Wash and Dry Wash. The terrain is characterized by steep elevation changes, with Buck Ridge and Monkey Hill overlooking the flats. Small-scale water sources like Cottonwood Spring and Hidden Spring indicate the critical points of survival for travelers and early inhabitants moving through the canyons. This map illustrates the complex drainage system of Salvador Canyon and Alder Canyon, providing a precise look at the landforms that have guided human passage through this part of the California desert.
