When the explorers arrived in 1774 the Athabascan language Indigenous were found “up-rivers” and dispersed from the coast. This was true for Alaska, BC, and Washington (Willapa and Chehalis Rivers), Oregon, and northern California. It was very cold here 15,000 years ago wtith a glacier covering Seattle to the height of 4 Space Needles; and sea level was as much as 400’ lower (with coastline villages) miles out into the Pacific Ocean
seabed. 4,500 years ago, the weather had plateaued to our historic levels with the sea levels rising to our present coastline. The Athabascans in western Alaska were spared from the glaciation. Might they have spread down the coast, flourished, and created a significant population, 10,000 BC to 2,000 BC? We wonder if a tsunami might then have wiped out an Athabascan civilization commanding the Cascadia Floristic Region Floristic Regions coast, leaving only remnant groups up-river. How large might the tsunami have been? Sea levels rising are not necessarily catastrophic events, they are a relocation and migration events. Earthquakes and tsunamis are catastrophic! What other reason might exist for the strange dispersion of the Pacific Rim’s Athabascan language family … in so many places, always “upriver” leaving the coast for new language groups to grow and prosper? Evidence is either under water or washed out to sea. (Large tsunamis come in 2 or more waves, as the 1st wave’s debris is being washed out into the sea, the following huge wave turns it to sand.) What might DNA testing of these Athabascan language groups indicate?
