2021 Map of Sombrero Peak

About this map

Sombrero Peak stands as the central high point in this high-desert landscape within the Tierra Blanca Mountains and the southern Sawtooth Mountains. The area is characterized by deep drainage systems like Bow Willow Canyon and the expansive Indian Valley, which transitions into the North Fork Indian Valley and its southern counterpart. Human presence is concentrated along narrow corridors like Canebrake Rd and Mccain Valley RD, leading to significant local sites such as the Manzanita Cem. The southwestern portion of the sheet is defined by the Tecate Divide, a prominent ridge separating the Simmons Canyon watershed from the interior valleys. The mapping of Old Mine Rd and Bia RD reflects the complex land management of this part of San Diego County, where isolated valleys like Thing Valley and Lost Valley remain tucked between the granite ridges of the In-Ko-Pah Mountains.
