A 40,000-yr record of environmental change from
Burial Lake in Northwest Alaska.
Quaternary Research, Vol. 74, pp. 156-165.
doi:10.1016/j.yqres.2010.03.007
Burial Lake in northwest Alaska records changes in water level
and regional vegetation since ~39,000 cal yr BP based on terrestrial
macrofossil AMS radiocarbon dates. A sedimentary unconformity is
dated between 34,800 and 23,200 cal yr BP. During all or some of
this period there was a hiatus in deposition indicating a major drop
in lake level and deflation of lacustrine sediments. MIS 3 vegetation
was herb-shrub tundra; more xeric graminoid-herb tundra developed
after 23,200 cal yr BP. The tundra gradually became more mesic after
17,000 cal yr BP. Expansions of Salix then Betula, at 15,000 and
14,000 cal yr BP, respectively, are coincident with a major rise
in lake level marked by increasing fine-grained sediment and higher
organic matter content. Several sites in the region display disrupted
sedimentation and probable hiatuses during the last glacial maximum
(LGM); together regional data indicate an arid interval prior to
and during the LGM and continued low moisture levels until ~15,000
cal yr BP. AMS 14C dates from Burial Lake are approximately synchronous
with AMS 14C dates reported for the Betula expansion at nearby sites
and sites across northern Alaska, but 1000-2000 yr younger than
bulk-sediment dates.

in the northwest Brooks Range, Alaska covering the last 39,000 years.
