GG354 Final: Canadian North Final AND Review Q/A
Document Summary
Initial human settlement of the north is closely linked to the retreat of glacial ice cover. There is debate over the advance across the bering land bridge and subsequent immigration through corridors through the mackenzie valley. Early patterns of settlement dependent on landscapes. Colvis theory: the covis people appeared out of nowhere and disappeared in the blink of an eye, appeared in 9,200 bc and vanished 500 years later. Theory proposed that the people came from siberia, where hunter-gatherer tribes lived, lived in the americas in the middle of an ice age. The ice age lowered sea levels and land that now under water was exposed, supposedly the clovis used the bering land bridge which is now under the bering strait to cross from siberia to alaska. A recession in the ice called the ice-free corridor would have allowed the colvis to migrate through the northern us, form there they traveled south and spread across the continent.
