About this map

Sombrero Peak stands as a central landmark in this high-desert region of San Diego County, where the Tierra Blanca Mountains meet the In-Ko-Pah Mountains. The landscape is defined by its complex drainage systems, including Canebrake Wash and the ephemeral Bow Willow Cr, which carve through deep canyons like Torote Canyon and Rockhouse Canyon. This 2015 survey reveals a terrain crisscrossed by essential mountain passages and remote routes such as McCain Valley Rd and Lost Valley Rd.

The western edge of the map features the Tecate Divide, a significant topographical break that separates the Thing Valley from the surrounding high country. To the south, Tule Cr winds through Lost Valley, illustrating the sparse but critical water resources that have historically dictated movement and land use in this arid environment. The presence of the Pepperwood Trl and various public roads highlights the ongoing utility of these ancient corridors for modern navigation.
