analyses on a ~3350 cal yr lacustrine sediment record include pollen, charcoal, loss on ignition,magnetic susceptibility,
and elemental geochemistry. Archeological evidence is derived from extensive settlement surveys
conducted near the study site. Results indicate nearby settlement and agricultural activity taking place in an
environment characterized by open forest from around 3350 to 950 cal yr BP. The fire history shows a dramatic
increase in burning during the Classic period, possibly reflecting changing agricultural strategies. A distinct band
of carbonate deposited from 1270 to 1040 cal yr BP suggests decreased hydrologic input associated with drier
conditions. Abrupt changes in proxy data around 940 cal yr BP indicate a cessation of human disturbance and
local abandonment of the area.
