The Mark O' Hatfield Wilderness lies just south of the sheer cliffs of the Columbia River Gorge. Most of the land adjacent to the river and along Interstate 84 is privately owned and often developed and, of course, outside the Wilderness boundary. The breaks of the gorge are spectacular basalt cliffs, rocky slopes, and rock outcroppings. Rugged and steep, the slopes of the Wilderness rise to a slightly uneven plateau and on to mountain peaks, talus slopes, and lakes with elevations ranging from approximately 100 feet near the river to 4,900 feet on Mount Defiance. Sparkling waterfalls and mossy-green cliff faces often highlight the deep drainages slashing through the broad, flat ridge tops. The main waterways--Herman Creek, Eagle Creek, and Tanner Creek--flow north toward the river, supporting borders of western hemlock and fir. Most of the 200 miles of trails follow drainages.
