Hole in the Wall Falls is the newest waterfall in the Columbia River Gorge. That statement might seem strange, but Hole in the Wall Falls was created by maintenance crews on the Columbia River Highway. The original highway crossed Warren Creek close to Warren Falls. Apparently, there was an ongoing flooding problem at Warren Creek and in 1938, highway supervisors decided that best way to remove the problem was to remove the creek. A pipe-like channel was blasted through the rock and Hole in Wall Falls was born.
