Wasson Creek

Located in Oregon’s Coast Range, Wasson Creek flows through lush, densely vegetated old-growth temperate rainforest. The streambed contains sections that are sandstone bedrock with numerous ledges and waterfalls descending in a series of stair steps. The largest, Devils Staircase, is the namesake of the surrounding wilderness, also designated in 2019. Wasson Creek is at the heart of this undeveloped area, a unique, pristine setting with limited access and few signs of human activity. The 10.1-mile designation includes two segments, both classified as wild. The Bureau of Land Management manages the upper 4.2 miles, and the U.S. Forest Service manages the lower 5.9 miles. A 1990 eligibility study found outstandingly remarkable scenery, recreational, wildlife, and ecological values.
