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: This is actually interesting. The music being played seems to be missing a chunk of the frequency spectrum for some reason.
gollark: It would need good amplifiers, I suppose, but it's possible. I'll have to survey all our listeners to determine how many actual listening people each thing corresponds to (factoring in time spent with it running but away from the computer, and such).
gollark: JS doesn't support **C** properly, so no.
gollark: It's not an arbitrary number, the backend *actually does* fetch this from the server doing all the streams.
gollark: No, icecast would record this.
