Late Glacial and Holocene Glacier and Vegetation Fluctuations
at Little Swift Lake, Southwestern Alaska, U.S.A.
Arctic, Antarctic, and Alpine Research, Vol. 36, No. 2, pp. 139-146.
Multiproxy data from Little Swift Lake, an alpine lake in southwestern
Alaska, provide evidence for pronounced late glacial and Holocene
environmental change. An alpine glacier upvalley of Little Swift Lake
retreated following the Younger Dryas chronozone, as evidenced by
sedimentological changes in the lake record. Glacier retreat was
accompanied by local and regional vegetation changes, including the
expansion of Betula and contraction of Cyperaceae, in response to
climatic amelioration. Warm, moist conditions between ~9800 and 8000
cal yr B.P. supported abundant Betula shrubs and high lake and
watershed productivity. Alnus rapidly expanded near Little Swift Lake
while the region cooled between 8000 and 7500 cal yr B.P.
Environmental changes at Little Swift Lake appear to have been roughly
synchronous with similar changes elsewhere in southwestern Alaska,
but late glacial and Holocene changes in other parts of Alaska were
different in nature and timing. The complex spatial and temporal
patterns of late glacial and Holocene environmental change throughout
Alaska point to the importance of local and regional-scale factors,
especially controls on moisture availability, as modulators of
site-specific responses to hemispheric- and global-scale climate forcing.
STUDY NOTES: Multiproxy sediment data covering the last 12,000 years from
Little Swift Lake, southwest Alaska. Data include major-element
geochemistry, grain size measurements, loss on ignition,
magnetic susceptibility, and pollen counts. Core LS-A,
a 575-cm-long sediment core, was recovered from Little Swift Lake
in 14.7 m of water in summer 1998.
The lake is 24 m deep and has 0.7 km2 surface area.
