The North Santiam River carves through this portion of the Willamette National Forest, defining the geography between Marion and Linn counties. The settlement of Idanha and the nearby area of New Idanha are situated along the riverbanks, where the topography transitions from the water's edge to significant elevations like Hoover Ridge and Coopers Ridge. This 2020 survey illustrates a landscape dominated by water and timber management, with unique features such as the Idanha Bog Pond and several high-altitude water bodies including Rainbow Lake, Bear Lake, and the Bruno Lakes.
