Cascade–Siskiyou National Monument, National Monument at Oregon-California border, United States.
Cascade-Siskiyou National Monument spans forests, woodlands, grasslands, and meadows where three mountain ranges meet along the Oregon-California border. The landscape shifts across different elevations, creating varied terrain and plant communities throughout the 114,000 acres.
This area was established as a protected monument in 2000, and its boundaries were significantly expanded nearly two decades later. The enlargement reflected growing recognition of the land's ecological value.
The region holds traces of several Native American peoples. Remains of settlements and gathering places reveal the deep connection the Modoc, Klamath, and Shasta maintained with this land for generations.
The monument offers marked trails for hiking, wildlife observation, hunting, and fishing across different elevations. Visitors should prepare for varying terrain and weather conditions when planning their visit.
This was the first United States monument designated specifically to protect biological diversity rather than a single landmark. Over 300 animal species inhabit the area, making it a refuge for many creatures.
