Lowell, Thomas V.

Sediment cores extracted from three lake basins in Northeast Ohio reveal a marked transition from organic rich late Holocene muds to sediments richer in clastics in two of the basins, while the third and smallest lake basin contained no such transition. Analyses of sediment cores from Long Lake were conducted at the LacCore facilities in Minneapolis, Minnesota and revealed an increase in magnetic susceptibility and gamma density measurements, which are consistent with an influx of eroded soils into the aquatic system. Radiocarbon dating of material gathered from the noted transition dates to the early 19>th) century. The drainage basins range in size from Odell Lake, which is 52 km>2) to Long Lake, at 6 km>2) to...
