Prairie Peak and Prairie Mountain anchor this high-elevation terrain in Lane County, where the headwaters of several major drainages originate. The landscape is defined by the complex hydrology of the South Fork Alsea River and the East Fork Lobster Creek, with deep drainages such as Billy Tower Canyon cutting through the ridges. A network of timber and access roads, including Bummer Creek Rd and the Fall Creek Access Rd, crisscrosses the slopes, providing passage through remote points like Gunsight Pass.
