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

gollark: You can get a rough high-level overview of it, but we've done that with brains.
gollark: They have billions of transistors in them, imaging them is hard itself, nobody actually knows how all the parts work, and they're designed with computerized design tools such that nobody knows what's going on with all the individual transistors either.
gollark: You can't really dissect a modern CPU and work out how it works, though.
