The Cascade–Siskiyou National Monument is a national monument that protects 86,774 acres (35,116 ha) of forest and grasslands at the junction of the Cascade Range and the Siskiyou Mountains in southwestern Oregon and northwestern California, United States. The monument is managed by the Bureau of Land Management as part of the National Landscape Conservation System and was established in a presidential proclamation by President Bill Clinton on June 9, 2000.
On January 12, 2017, President Barack Obama expanded the monument by 48,000 acres (19,000 ha). The expansion contains 5,000 acres (2,000 ha) in Northern California, in addition to 43,000 acres (17,000 ha) in Oregon.
Native Americans are known from archaeological excavations to have inhabited the region for thousands of years. Nearly 100 dwelling and root-gathering sites belonging to the Modoc, Klamath, and Shasta tribes have been uncovered to date. By the 1880s, they had been completely replaced by white settlers, whose mining cabins still dot the region.
Natural features in the monument include Pilot Rock, a volcanic neck or interior of an extinct volcano, similarly formed as Devils Tower in Wyoming, and the Soda Mountain Wilderness.
