Champlain period \Cham*plain" pe"ri*od\ (Geol.)
A subdivision of the Quaternary age immediately following the
Glacial period; -- so named from beds near Lake Champlain.
Note: The earlier deposits of this period are diluvial in
character, as if formed in connection with floods
attending the melting of the glaciers, while the later
deposits are of finer material in more quiet waters, as
the alluvium.
