2018 Map of Palomar Observatory

About this map

The Palomar Observatory stands as a prominent landmark on the high ridges of Palomar Mt, surrounded by the protected lands of the Cleveland National Forest. This 2018 survey documents the intricate network of mountain roads and valleys north of La Jolla Amago, where the landscape is defined by the San Luis Rey River and its numerous tributaries like W Fork San Luis Rey River and Cedar Cr. The map details a series of high-elevation meadows and clearings, including Mendenhall Valley, Colb Valley, and Pedley Valley, which suggest a history of seasonal grazing and ranching. Access to these remote areas is provided by a complex system of fire roads and truck trails, such as Palomar Divide Rd and Mesa Truck Trl, connecting isolated settlements like Palomar Park to the broader San Diego County region.
