2021 Map of Seventeen Palms

About this map

Seventeen Palms Spring serves as a critical water source in the arid transition between the Santa Rosa Mountains and the lower Imperial Valley. This region is defined by an intricate network of desert drainage systems, including Wonderstone Wash, Big Wash, and the Arroyo Salada, which illustrate the complex hydrology of the Colorado Desert. The northern edge of the map captures a small portion of the Salton Sea coastline near Silver Sands Dr. Evidence of historic water management and travel is visible through features like the Anza Ditch and the Truckhaven Trl, which navigate the rugged terrain near Rainbow Rock. The boundary between San Diego and Imperial Counties bisects these desert washes, marking a landscape where springs like Four Palms Spring provided essential stops for early travelers across these expansive basins.
