Stratigraphy of the Colorado Creek mammoth locality, Alaska

Auteurs :
THORSON, R. M.
GUTHRIE, R. D.

Description :
From sedimentologic interpretations and radiocarbon dates, the AA. propose a polycyclic taphonomic model for thaw gullies governed largely by slope aspect, rather than regional climate, and in which mixing between faunal horizons is more likely than not. Variations in the rate of silt influx and the position of the permafrost table provide a paleoclimatic proxy record that can be correlated to other records in eastern Beringia.
