Late Glacial-Holocene Climatic Changes of Alberta: The Record from Lake Sediment Studies. In The Impact of Climatic Fluctuations on Alberta's Resources and Environment, edited by K. R. Leggat and J. T. Kotylak, pp. 47-60. Proceedings of the Workshop and Annual Meeting of the Alberta Climatological Association, Report W.A.E.S.-1-81. A.E.S. Western Region, Environment Canada.
Report that they have examined 16 lakes or sites on a west-east transect through central Alberta: Gregg Lake, Mary Gregg Lake, Fairfax Lake, Goldeye Lake, Lake Wabamun, Smallboy Lake, Muskrat Bog, Lac Ste. Anne, Lake Isle, Hastings Lake, Cooking Lake, Elk Island Park, Joseph Lake, Baptiste Lake, Lofty Lake, Moore Lake. Paper includes a pollen diagram and some preliminary discussion of the Fairfax Lake record, includes total a pigments curve for Gregg Lake and Fairfax Lake, a summary pollen diagram, percentage diatom community diagram and preliminary discussion of the Moore Lake record, and a summary stratigraphic diagram for the Lofty Lake record. They note that detrital coal in the sediment at Fairfax Lake makes the basal date (of around 11,250 yr BP) somewhat doubtful.
