Title: The Origins of the Norridgewock Sand Plain, Somerset County
Abstract: The Sand Plain at Norridgewock, Maine, is an unusually flat area over a mile across, lying nestled between the rolling glaciated hills and associated deposits of central Maine. In the past it has been mapped as a fluvial (stream-deposited) unit and as the last nearshore deposit atop the Presumpscot marine clays. Independent evidence exists for both hypotheses. Recent work, however, has apparently resolved the issue: a deep, broad but unseen channel underlies the placid surface façade, big enough to have carried the ancestral Kennebec River. The big question now is, where did the river go from here?
