Late Holocene Pollen Stratigraphy of Lake Louise, Manitoba.
Current Research 2001-B1. Geological Survey of Canada, Ottawa,
Ontario, Canada 14 pp.
Site discussed: Lake Louise. Part of a
project to investigate the history of flooding of the Red River, by
looking at sediments in oxbows or channel scars close to river.
Site is shallow perennial lake, eutrophic for part of year.
Receives floodwaters periodically. Base of record dates to around
1600 yr BP. Zone 1 (lower) dominated by NAP, with some oak and pine
pollen. Rather than oak savannah, this may represent more wooded
vegetation in moister habitats near river and lake. Represents
vegetation prior to EuroCanadian incursion. Zone 2 (30 cm to
surface) shows increase in NAP, especially grass and
Ambrosia pollen. Probably represents land clearance and
disturbance. Dates back to 19th century, though greater precision
is not possible. Zone exhibits a greatly increased sedimentation
rate. Some sediment may be from agricultural disturbance, some may
be from Red River high flows. Report is available only on-line as
a PDF file.
