About this map

Idanha sits at the heart of this mid-1990s survey, where the Santiam River and the North Santiam Highway carve a path through the timberlands of the Willamette National Forest. The landscape is defined by the sharp transition between industrial use and mountain wilderness, evidenced by a Gravel Pit and a Trailer Park near the settlement, contrasted against the high elevations of Boulder Ridge and Coopers Ridge.

Downstream to the northwest, the headwaters of Detroit Lake appear near the historic locale of Hoover. Local hydrology is intricate, with features such as Whispering Falls, Mud Puppy Lake, and the remote Bruno Lakes dotting the drainages. The map serves as a detailed record of the 1990s forest infrastructure, showing various spurs off Highway 22 and the county line between Marion and Linn counties as it traverses the river valley.
