There was a huge lake, first in the Canadian arctic. It was the remnants of a ice sheet that was melted by an impact of a asteroid or comet. That sheet was vaporized at the site and melted for hundreds of miles. That water flowed down into the basin that makes up the plains of the US.
Further down the line, that water ran off to the Gulf of California down what is today the Colorado river basin and the Grand Canyon area. You can see the water marks carved into the entire Western part of the continent.
Some of those things took thousands of years. Others were carved in a few years.

Something the size of a football field hits us...and its lights out for everyone but the roaches.

And then gawd created Maxxim Magazine just in time for summer...
Man, I hate living in California.
The rains finally stopped, the sun came out and the women began their annual donning of summer wear...
Hmmm.
All this time I have been convinced that the Western States' role in the catastrophes was the break in the ice dam holding back Lake Missoula between 15,000 and 13,000 years ago.
Whether the meteor strike and the plains "lake" played a part may have been many millennia apart.
