2020 Map of Silica Mountain

About this map

The Umpqua National Forest dominates the southern reaches of this landscape, where the rugged crest of the Calapooya Divide separates the watersheds of the Willamette and Umpqua river systems. This terrain is defined by its dramatic relief, rising from the valley floors toward high points like Silica Mtn, Snow Peak, and Huckleberry Mtn. A network of forest roads and resource management tracks, such as Mosby Creek Rd and numerous BLM routes, crisscrosses the slopes, providing access to the deep drainages of E Fork Mosby Cr and W Fork Mosby Cr. The map captures a moment in recent management of these public lands, showing the intricate hydrology of the western Cascades where Huckleberry Spring feeds into the winding creek systems that historically supported the regional timber economy.
