Opal Creek

The Opal Creek Wilderness and the neighboring Bull of the Woods Wilderness comprise the largest contiguous area of low-elevation old growth left in Oregon. Opal Creek’s ancient rainforest is a remnant of the conifer forests that once stretched from the Pacific coast to the crest of the Cascades, and from southeast Alaska to the northwest corner of California. This region, also known as Cascadia, contains trees and other organisms uniquely adapted to the heavy rainfall—70-100 inches per year–including the most diverse moss species of anywhere in the world.
