2024 Map of Silica Mountain
USGS Topo · Published 2024About this map
The Calapooya Divide serves as a prominent natural boundary in this high-elevation corner of the Pacific Northwest, separating the drainages of the Umpqua National Forest from the lands to the north. This landscape is defined by its complex network of watercourses, including the many forks of Mosby Creek and the southern headwaters of Sharps Creek. The terrain is punctuated by a series of named summits such as Silica Mtn, Holderman Mtn, and the high point of Snow Peak.
