An ~11,200 year paleolimnological perspective for emerging
archaeological findings at Quartz Lake, Alaska.
Journal of Paleolimnology, Vol. 48, No. 1, June 2012, pp. 83-99.
DOI: 10.1007/s10933-012-9610-9
Wetlands and lakes in the Tanana Valley, Alaska, have provided
important resources for prehistoric humans who inhabited this
region. We examine an ~11,200 cal yr BP record of environmental
and paleolimnological changes from Quartz Lake in the middle
Tanana Valley. Our data are also presented in the context of
recent archaeological findings in the lake's general vicinity
that have 18 associated AMS 14C dates. We analyzed the stable-
carbon and nitrogen isotope composition of total organic matter
from the core, coupled with oxygen and carbon isotope analyses
of Pisidiidae shells (fingernail clams), in addition to chironomid
assemblage changes. Lacustrine sediments began to accumulate at
~11,200 cal yr BP. Initially, autochthonous production was low
and allochthonous organic input was negligible between 11,000
and 10,500 cal yr BP, and were associated with relatively cool
conditions at Quartz Lake at ~10,700 cal yr BP. After 10,500
cal yr BP, autochthonous production was higher coincident with
a shift to chironomid assemblages dominated by taxa associated
with warmer summer climates. A decrease in d13C values of total
organic carbon (TOC) and organic content of the sediment between
9,000 and 4,000 cal yr BP may indicate declining autochthonous
primary production. This period ended with an abrupt (~7 ‰)
decrease in the d18O values from Pisidiidae shells at ~3,000
cal yr BP, which we hypothesize represented an episodic
connection (flood) of the lake with flow from the nearby
(~6 km) Tanana River. Our findings coincide with evidence for
major flooding at other locations connected to the Tanana River
and further afield in Alaska. From ~3,000 cal yr BP Quartz Lake
subsequently appeared to become a relatively closed system,
as indicated by the d18OPisidiidae and d13CPisidiidae data
that are positively correlated and generally higher,
which also correlates with a shift to moderately higher
abundances of littoral chironomids. The cause of the transition
to closed-basin conditions may have been geomorphic rather than
climatic. This evidence of a progressively stronger evaporative
influence on the lake's closed hydrology after ~3,000 cal yr BP
is consistent with our modern d18O and dD water data from Quartz
Lake that plot along a regional evaporative line we base on
isotopic measurements from other local lakes and rivers.
