The Santiam Junction vicinity is listed by the National Register of Historic Places as the site of the Oregon Pacific Railroad Linear Historic District, which consists of roughly 20miles of the old railroad grade between Idanha and the line's Cascade Range summit.[5]
Geologically, much of the area is a lava bed created during a period of volcanic activity around 1000 B.C.[6]
