As the Wisconsin Glaciation receded, it broke up into smaller glacial ice sheets, which in turn broke up into smaller ice sheets, and eventually into individual glaciers. At the right are the Cordilleran and Laurentide ice sheets produced by the melting of the Wisconsin Ice Sheet,- as they were 13,000 years ago.

Here we see how the land of the MacKenzie Water Basin emerged first, providing an early path for the Clovis people to follow as they began to populate the Americas.

It is along the southern regions of this path that the Clovis Kill Sites are most concetrated.  Oddly enough, Clovis points are not found along the northern portion of this route. In fact the Clovis point I found, is the most northern find of any Clovis point., at 57° 7' N. Latitude.
