Thanks for this fascinating map. My dad was born in Buhl, Idaho, a little west of Twin Falls. He’s been studying the geology of the area for a little while and told me about the hot spot which has been moving and which is now under Yellowstone.

My wife and I are going to visit there this summer and we hope to swing by Yellowstone. Might as well try to visit before it blows up.

You're welcome. There is even some speculation (I don't know how credible it is) that the hot spot may have been initially caused by an asteroid impact in the southeast corner of Oregon. The trail of blown away mountains begins in Oregon, the very first dating back to 16.5 million years ago.

The hot spot is more or less stationary. It's the North American tectonic plate that's moving. Note the yellow box and arrow at the top right of the above illustration.
