Trout Creek Hill is a small Pleistocene basaltic shield volcano in Washington, United States. Located in Skamania County, Trout Creek Hill rises to an elevation of 2,946 feet (898 m). It is part of the Cascade Volcanic Arc, located in the Marble Mountain-Trout Creek Hill volcanic field.
Trout Creek Hill produced a lava flow about 340,000 years ago that traveled 20 km (12 mi) southeast, which dammed the Columbia River for a short period of time.[2] A shield volcano, it has two cinder cones atop it. The nearby area is forested and hosts the Wind River Experimental Forest, and it can be hiked.
