POST-GLACIAL STRATIGRAPHY AND HUMAN IMPACTS IN UPPER BOLTON LAKE, EASTERN CONNECTICUT: IMPLICATIONS FOR AN ATLANTIC WHITE CEDAR STAND
Presently, Upper Bolton Lake is dammed at its southern edge by a causeway and derelict culvert system, and in the northeast, transitions into a tree stand of Atlantic White Cedar. State government plans to modify the lake’s water levels, which may impact this protected tree stand. Concerned about such impacts, local interest groups asked that we investigate the geologic context and history of water level change. Multiple vibracores will be collected at the site to characterize Holocene and Anthropogenic stratigraphy near the cedar swamp. These cores will be described and sampled for 14C dating, grain size, organic content (measured by loss-on-ignition) and heavy metal content (Pb, Zn, and Cu), measured using a handheld XRF. Investigation results will be combined with a Ground Penetrating Radar (GPR) survey coordinated by the Natural Resources Conservation Service. Overall, this project contributes to research regarding Holocene environmental change and human impacts within the New England landscape while also informing the questions of local residents.
