"Oregon Caves National Monument is small in size, 480 acres, but rich in diversity. Above ground, the monument encompasses a remnant old-growth coniferous forest. It harbors a fantastic array of plants, and a Douglas-fir tree with the widest known girth in Oregon. Three hiking trails access this forest. Below ground is an active marble cave created by natural forces over hundreds of thousands of years in one of the world's most diverse geologic realms. The 480 acre Oregon Caves National Monument was created by Presidential proclamation in 1909. The proclamation states the public interests will be promoted by reserving these caves with as much land as necessary for the proper protection thereof. The Monument is located in the Siskiyou Mountains of the Klamath Geologic Province in southwest Oregon at elevations from 3800 to 5460 feet. Temperatures typically range from 20 to 40 degrees Fahrenheit during the winter and from the 50 to 90 during the summer. The cave temperature is 42 degrees Fahrenheit year round."
