Groves of old growth Douglas-fir, hemlock and cedar grow in lower elevations of the Mark O. Hatfield Wilderness. The north part of the Wilderness has features characteristic of the Columbia River Gorge, such as towering basaltic cliffs and many waterfalls. Higher elevations are home to forested plateaus and ridges with hanging meadows, subalpine lakes, and panoramic views of the Cascade Range and the Columbia River Gorge.
