Cascade-Siskiyou National Monument Junior Ranger Book

On June 9, 2000, the Cascade-Siskiyou special area was proclaimed a national monument in recognition for its unique geology, biology, climate, and topography. At nearly 113,000 acres, this national monument is mostly located in Oregon, with a small portion in northern California. The Cascade-Siskiyou National Monument is situated at the crossroads of the Cascade, Klamath, and Siskiyou mountain ranges, with elevations from 2,100 to 6,100 feet. This convergence of three geologically distinct mountain ranges represents an outstanding ecological wonderland, an area with unparalleled biological diversity, and a tremendously varied landscape.
