This map shows Lac LaLoche and area.   South of the Village of LaLoche is bush country that opens up onto the Great Plains, and finally the Cyprus Hills which cross the Canadian US border where there is a heavy concentration of Clovis Kill Sites.  One of the largest Clovis Kill Sites is at the mud flats of St. Mary's Irrigation Reservoir near the town of Cardston in Southwestern Alberta, Canada.

The Cordilleran Theory is the best one to date, in spite of the recent challenge from a few Anthropologists who favour the Bering Land Bridge crossing,- followed by a trek down a coastal plain that rises and falls with the Bering Land Bridge. I find the notion that the land which sank West of the mountains was a coastal plain is wishful thinking.   I believe the land West of the mountains will prove to be just an extension of our current rocky coast.
