The Early Paleo-Eskimo is the first of three distinct periods of human occupation recognized by archaeologists in the eastern North American Arctic, the others being the Late Paleo-Eskimo and the Thule. Dates for these occupations vary according to specific geographic region and cultural historical perspective, but it is generally agreed that the Early Paleo-Eskimo approximately spans the period from 4500 BP to 2800-2300 BP.
