Asians crossing Beringia on foot found their way blocked by pack ice. As the ice sheets parted they poured through in small groups wave upon wave for thousands of years.

Others came by boat down the Pacific Coast arrived earlier than did the walkers.

Within three thousand years they settled both North and South America as far south as Monte Verdi (central Chili) 11,000 BC. 


When paleo-man came south-east through Canada, the dinosaures were 65 million years extinct, but large animals like mastodons, mammoths and giant sloths still roamed free.

On this continent they believe that the last one was killed or died about 12,000 years ago, and that they went extinct within a few hundred years after man came.

One supported theory of their demise was loss of habitat and food they normally ate.

Another supported theory is that they were hunted to extinction.

Both theories apparently contributed to their demise. 

A third lesser supported theory is they died of a disease, or diseases, brought by man.

The oldest skeletal remains of paleo-man found on this continent is Kennewick Man who was found in the Columbia River near Kennewick in Washington State.

His cranium was found intact in 1996 and subsequent searches found 350 more bones and pieces of bones, enough to put together a nearly complete skeleton.

 The bones were ex-rayed and radio-carbon dated at 9,300 years old.

Under close examination, he had an arrowhead imbedded in his hip, but he survived the injury as bone had partially enclosed it. This Cascade Point is unlike the Clovis Points found all over the United States and South America. Did this man accidentally fall on his arrow, or did someone else shoot him? The mystery is who shot Kinnewick Man?

Clovis Points are the most common spear and arrow points found in North America. They point to broad distribution of the Clovis Culture who by DNA descended from Paleo-Man.

From this culture descended the Indians we know today and which will be covered under separate cover entitled Indian History of Navajo County, Arizona.
