1986 Map of Sinker Mtn

About this map

The Willamette National Forest dominates this mid-1980s landscape, where a dense network of watercourses feeds into the Middle Fork Willamette River. The terrain is defined by prominent elevations such as Alpine Ridge and the distinct peak of Sinker Mtn. Human activity in this timbered region is marked by numerous industrial sites, including a series of Quarry and Borrow Pit locations that indicate ongoing road maintenance and resource extraction within the forest boundaries. Recreational and navigational landmarks like the Elk Camp Shelter, Gold Point, and several Footbridge crossings suggest a landscape managed for both utility and backcountry access. Local nomenclature is particularly evocative, with labels like Nevergo Creek, Puma Creek, and Elephant Rock providing a sense of the region's topographical character. The presence of multiple gates across forest roads reflects the controlled access common in managed federal timberlands during this era.
