Wilderness Landscape & Natural Heritage
Located in northern Oregon, the Mark O. Hatfield Wilderness spans over 65,000 acres and stretches along the Columbia River Gorge. This wilderness is characterized by its diverse topography, ranging from lush river valleys to high ridges with panoramic views. The region is home to old-growth forests, numerous waterfalls, and significant biodiversity, with various plant and animal species, including western hemlock and Douglas fir. It is a haven for outdoor enthusiasts seeking solitude and adventure, offering ample opportunities for hiking, backpacking, and wildlife observation. Historically, the area is named after Mark O. Hatfield, a former U.S. senator known for his environmental legacy. The wilderness attracts visitors with natural landmarks like Eagle Creek and Larch Mountain, and its clear, flowing waters are part of the ancient geologic forces of the Columbia River Basalt Group. Its appeal lies in the serene, untamed beauty and the challenge of exploring its intricate trail network.
