Glacial Lake Nantucket Sound
# Glacial Lake Nantucket Sound

Glacial Lake Nantucket Sound was a glacial lake that formed during the late Pleistocene epoch inside modern Nantucket Sound. After the Laurentide Ice Sheet retreated, glacial ice melt washed over the terminal moraine of Cape Cod and the glacial meltwater settled in the modern day sound, creating the lake.
