Which explains why archaeological evidence of the earliest humans known on this continent were first discovered in Clovis, New Mexico (hence they are now referred to as the Clovis people) and other parts of the country in the south and southeast, where they were driven over the course of centuries by the advancing glaciers . . which also removed all traces of earlier settlements. BTW, buffalo migrated south as well.
