Multidisciplinary research programs conducted within the Alberta portion of the 'Ice-Free Corridor' since 1986 as part of the Archaeological Survey's 'First Albertans' project have used studies of palaeogeography and palaeoenvironments to formulate archaeological search strategies. This approach has resulted in the discovery of two new important sites — Saskatoon Mountain (GhQt-4) and the James Pass Meadow Complex (EkPu-3 to 9) — that are yielding information on terminal Late Wisconsinan/Early Holocene human occupation of the corridor. Both sites are dated by AMS or conventional radiocarbon dates to the millennium 10,000–9,000 BP. In the fifteen years since the 1978 AMQUA Conference on the Corridor, other researchers have identified four additional significant Paleo-Indian sites in this region. So far, none confirm human occupation of the 'Ice-Free Corridor' region before about 11,000 BP.
