Gould Pond, Maine: late‐glacial transitions from marine to upland environments
Gould Pond sediments are unusual in North America in that they include a continuous record of change from marine to freshwater conditions during the late‐glacial period, with a wide array of micro‐ and macrofossils deposited during a period of high sedimentation rate. Marine waters, much colder than...

Marine recession, due to isostatic rebound of the land, occurred from c . 12,800–12,200 BP. The lake water was completely freshened by 12,000 BP.
