Tecate Divide serves as a prominent backbone for this corner of San Diego County, separating the drainages that feed the McCain Valley from those sloping toward the Campo Indian Reservation. High-altitude communities like Live Oak Springs and Boulevard are joined by the winding route past Calexico Lodge, while the Manzanita Indian Reservation dominates the northern terrain. The infrastructure of the late 1950s is remarkably detailed here, showing the San Diego and Arizona Eastern rail line cutting through the southern landscape near Music Mtn. Local genealogy and social history are anchored by the St James Cemetery and the Clover Flat Sch, alongside the original Post Office in Boulevard. The landscape is a complex network of seasonal watercourses like Tule McCain Creek and Walker Creek, revealing how early settlement patterns followed these vital resources across the high desert.
