Document Summary
Spread of upper paleolithic people: beringia land bridge, northern asia (siberia) to alaska, open by 30,000 ya. Ice sheets covered: western canada (cordilleran, eastern canada & northern u. s. (laurentide, pacific coastal route, moved along pacific coast from asia on boats, 17-15,000 ya, h2o transport along pacific rim, diverse coastal ecosystems\ Paleoindians of north america: 13,000 ya, fluted projectile points, hunters of megafauna, kennewick man. Epoch now: holocene 10kya present time: end of ice age, glaciers melted, rising global temperatures, temperate forests, seasonality, regional diversity regional environmental conditions, end of megafauna.
