Yellowstone?
The location between Yellowstone and the volcanoes of Washington State can’t be just a coincidence, can it?
That is also where the ‘badlands’ are.
A lot of weird topology that looks like a giant flood of water suddenly washed over the area.
Just like ALL of north Africa (take a look) which has the ‘Eye of Africa’- a set of concentric rings that do not look natural (man-made?) and are similar to how Atlantis was described.
Since 3/4ths of the earth’s surface is water I bet a good sized meteor would displace a whole bunch of water.
