Importance of the Rossendale Site in establishing a deglacial chronology along the southwestern margin of the Laurentide Ice Sheet

Authors(s) and Affiliation(s)



Dates of 12 400 and 12 100 yr B. P. for moss at the Rossendale site in Manitoba have long been a key for those advocating an " early " deglaciation chronology in this region. However, new dates for wood from this site and paleoecological interpretations of ostracods, molluscs, and the dated moss all support a " young " deglacial scenario. The ice margin appears to have retreated into the southern Lake Agassiz basin after 12 000 yr B.P. and north of the Rossendale site by 11 000 B.P. About 10 000 yr B.P., following the Moorhead low-water phase, Lake Agassiz rose to the Campbell level. The dated organic matter at Rossendale was deposited in a lagoon behind the Campbell beach
