Dog Mountain is a steep Columbia River Gorge summit in Washington, rising abruptly from near river level to 2,948 feet above State Route 14 east of Stevenson. It is best known for a demanding 6-mile hiking trail that climbs through dense forest and meadows to broad summit views of the gorge and nearby peaks. A fire lookout stood near the top from 1931 until 1967, watching for fires across the river in Oregon's Mount Hood National Forest before road access and aerial surveillance made it unnecessary. Especially famous for spring wildflowers, the mountain attracts many hikers but is also known for steep terrain and serious hazards.
