Description :
Sediment cores from 3 proglacial lakes in northern Banff National Park, Alberta, preserve a record of Holocene glacial activity upvalley which is more continuous and better dated than available surficial records. Dating of the cores is based on tephrochronology and 16 AMS C 14 ages of terrestrial macrofossils. In particular, the lacustrine record provides information about the onset and duration of the Altithermal interval and on the timing and relative magnitudes of other Holocene glacier recessions, as well as a suggestion of a possible minor Altithermal glacier advances.
