About the Cascade-Siskiyou National Monument
Stewarded by Friends of Cascade-Siskiyou National Monument, Soda Mountain Wilderness Council
This 54,000 acre national monument was designated in 2000. At the intersection of the Cascade, Klamath and Siskiyou Mountain ranges, the rugged, remote region has tremendous biodiversity. Elevational changes, moisture patterns, and a unique assemblage of geologic formations create a veritable “Ark” of biodiversity. This ecological diversity includes three endemic freshwater fishes, Jenny Creek’s freshwater snail populations, rough skinned newts, kangaroo rats, pygmy nut hatches and northern spotted owls. Cultural history is also widespread throughout the monument with almost 100 sites of prehistoric use, and more recent signs of pioneer history throught the Applegate and Oregon-California Trail.
