About this map

Mt Bruno and the surrounding high country of the Willamette National Forest define this landscape along the border of Marion and Linn counties. The terrain is a network of ridges and drainages, marked by prominent elevations like Triangulation Peak, Outerson Mtn, and the distinctive Spire Rock. Water flows through deep-cut valleys via the North Santiam River and the S Fork Breitenbush River, with several alpine lakes such as Pamelia Lake, Peasley Lake, and Jo Jo Lake tucked into the higher benches.

Winter access is documented through specialized routes including the McCoy #1 - Shelter Route (Snow) and the McCoy #2 - Little Pigeon Route (Snow), which connect clearings like Pigeon Prairie and Little Pigeon Prairie. The map captures the complex system of forest ridges, from Boulder Ridge to Woodpecker Ridge, which served as critical landmarks for early surveyors and contemporary forest management alike.
