Changes in the Bathymetry and Volume of Glacial Lake Agassiz Between 11,000 and 9300 14 C yr B.P.
The volume and surface area of glacial Lake Agassiz varied considerably during its 4000-year history. Computer models for seven stages of Lake Agassiz were used to quantify these variations over the lake's early history, between about 11,000 and 9300 14 C yr B.P. (ca. 13,000 to 10,300 cal yr B....
