Trout Creek Hill[edit]

Trout Creek Hill is a small Pleistocene basaltic shield volcano in Washington, United States. It 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.[3]

West Crater[edit]

West Crater is a small andesitic lava dome with associated lava flows in southern Washington.[3]
