Martinez Mountain dominates this portion of Riverside County, where the high desert terrain meets the development of the Coachella Valley. The map captures a transitional landscape where suburban infrastructure, such as Washington St and Avenue 60, abruptly gives way to a network of steep canyons and natural drainage systems. Water remains a critical element of the topography, evidenced by the presence of Agua Alta Spring and seasonal watercourses like Guadalupe Cr and Bear Cr.
