bubblykiss Posted August 31, 2015 #2 Share Posted August 31, 2015 The Great Plains were managed landscape. During the Colombian Exchange the native population picked up a lot of plagues and died en masse which let the land revert back to what it was. We should be shocked that anybody lived through the dying rather than the fact that there once existed massive amounts of people spread across these landmasses.
