Evidence has recently come to light that suggests that peoples of European decent were roaming N. America long before mongoloid peoples crossed the Bering land bridge. It's thought that gatherers hunting wholly mammoths tracked their quarry across the Atlantic ice shelf and eventually settled in N. America. Though evidnce suggests that they were driven out by the mongoloids, who enjoyed superiour numbers.

In any event, the pacification of native Americans was just another example of history repeating itself. Not entirely sure why the European settlers are always painted as the bad guys, seeing as exactly the same thing was happening - and had happened, for thousands of years - the world over.
Kennewick is on the Pacific coast. I agree that there probably were people here from various Continents at different times in history and even at the same time in history.
