Latourell Falls is a waterfall along the Columbia River Gorge in the U.S. state of Oregon, within Guy W. Talbot State Park. The Historic Columbia River Highway passes nearby, and at certain locations the Lower falls are visible from the road. Latourell is unique among the best-known Columbia Gorge waterfalls, in the way that it drops straight down from an overhanging basalt cliff. Most of those falls (even the famous Multnomah Falls) tumble to some degree. Latourell Falls is an excellent example of columnar basalt formations.
