Oregon Caves National Monument



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.

Monument Overview

Oregon Caves National Monument is a small park unit located in the heavily wooded Klamath Mountains of southwest Oregon. The climate of the region is strongly influenced by the ocean which contributes to relatively mild summers and winters as well as 50 inches of rain per year. The elevation at Park Headquarters is 4,000 feet and resulting in comfortable summer temperatures and snowy winters.

The primary resources of the Monument include: Three miles of marble caverns, old growth forests and a historic lodge. The caverns contain one of the largest assemblages of endemic cave dwelling insects in the United States and, recently, it has gained notoriety for the Pleistocene aged jaguar and grizzly bear fossils found in some of the deeper chambers. Bear tracks and scratch marks on a mud wall in the same section of the cave are suspected to Pleistocene in age.

The region represents a unique geology composed primarily of bits and pieces of ocean crustal rocks (ophiolite). Some geologic sections are composed entirely of serpentine rock and soils which support many unique plant species. It is this unique soil that makes the northern Klamath Mountains well known for their botanical diversity and assemblages of endemic plants.

Oregon Caves National Monument is situated high in the Illinois River watershed, a major salmon and steelhead spawning waterway that feeds into the Rogue River near Gold Beach, Oregon. Part of this river flows through the Kalmiopsis Wilderness Area where narrow canyons make it a popular rafting and kayaking destination. Many deep swimming holes can be found all along this river.
