Agassiz, Lake
(A-guh-see), glacial lake of the Pleistocene
epoch; c.700 mi/1,127 km long,
250 mi/402 km wide. Formed by the melting of
the continental ice sheet some 10,000 years ago; covered much of
present-day NW Minn., NE N.D., S Manitoba, and SW Ont. The lake was
named in 1879 in memory of Louis Agassiz for his contributions to the
theory of the glacial epoch. L. Traverse, Big Stone L., and the
Minnesota R. are in the channel of prehistoric R. Warren, L. Agassiz's
original outlet to the S. As the ice melted, the water drained E into
L. Superior; after the ice disappeared, N into Hudson Bay, it left
lakes Winnipeg, Manitoba, and Winnipegosis, Red L., L. of the Woods,
and other smaller lakes. The Red R. valley now occupies the lake bed
and is an important crop-growing region due to its rich soil.
