Palomar Observatory stands as the primary landmark on this 2015 study of the high-elevation terrain within the Cleveland National Forest. The landscape is defined by a series of isolated upland basins including Mendenhall Valley, Dyche Valley, and Pedley Valley, which supported grazing and seasonal habitation long before the modern scientific installations. To the south, the San Luis Rey River and its West Fork drain the rugged slopes of Aguanga Mtn and High Point Mtn.
