	Lake Agassiz - Wikipedia, the free encyclopedia
		Lake Agassiz was an immense lake—bigger than all of the present-day Great Lakes combined—in the center of North America, which was fed by glacial runoff at the end of the last ice age.
		The lake's modern-day remnants, the largest of which is Lake Winnipeg, dominate the geography of Manitoba.

		Agassiz, Lake, glacial lake of the Pleistocene epoch, c.700 mi (1,130 km) long, 250 mi (400 km) wide, formed by the melting of the continental ice sheet some 10,000 years ago; covered much of present-day NW Minnesota, NE North Dakota, S Manitoba, and SW Ontario.
		The lake was named in 1879 in memory of Louis Agassiz for his contributions to the theory of the glacial epoch.
		Lake Traverse, Big Stone Lake, and the Minnesota River are in the channel of prehistoric River Warren, Lake Agassiz's original outlet to the south.

	Lake Pepin - Mississippi Valley Partners (Site not responding. Last check: 2007-10-21)
		The Mississippi River Valley and Lake Pepin were formed when the large glacial Lake Agassiz began flowing southward, near the intersection of Minnesota and North and South Dakota, through the glacial Warren River about 12,000 years ago.
		In the late 1600s the lands around the lake were under the control of the Dakota Sioux, but their ownership was disputed by the Chippewa at the lower end of the lake.
		The name "Lake Pepin" was given to the lake by two French explorers in honor of "Pepin the Short" who ruled France from 740 to 768 AD and was the father of Charlemagne.

	Glacial Lake Agassiz
		Lake Agassiz, named after Swiss geologist Louis Agassiz, was a 700-mile long by 200-mile wide lake that once covered much of Manitoba as well as parts of Ontario, Saskatchewan, Minnesota, and North Dakota.
		The fertile soil of the Red River Valley on the Minnesota-North Dakota border is also a vestige of the clay-like silt that accumulated on the bottom of the lake (Agassiz Project, 1996).
		Lake Agassiz's more than 4000-year lifespan coincided with the existence of such now-extinct animals as the giant beaver, woolly mammoth, mastodon, giant short-faced bear, and giant ground sloth (Zimmerman, 1996).

	THE GLACIAL LAKE AGASSIZ--Preface
		CHAPTER V: HISTORY OF LAKE AGASSIZ.--The records of glacial lakes are their outlets across present lines of watershed; eroded cliffs, beach ridges, and deltas at the levels of the former outlets; and lacustrine sediments in the basin inclosed by the old shores.
		With the uncovering of the course of the Nelson River, Lake Agassiz ceased to be held by the ice barrier, and became Lake Winnipeg.
		Epeirogenic uplifting of the area of Lake Agassiz, increasing in vertical extent from south to north, gave to its beaches a northward ascent, and caused the several shores of its southern part to become double or multiple as they are traced northward.

		Lake Agassiz was an immense glacial lake that formerly covered much of present-day northwestern Minnesota, eastern North Dakota, southwestern Ontario, and southern Manitoba.
		The historical existence of Lake Agassiz is indicated by deltas, created where former rivers flowed into the lake, and by the great Laurentide Ice Sheet.
		The water from that lake cut a direct path from Mankato to the Twin Cities of Minneapolis and St. Paul along the path that had already begun by the draining of Lake Agassiz.

		The stratigraphy of the sediments of the Red River Valley imply that the Valley was repeatedly occupied by glaciers, lakes, and rivers.
		The history of glacial Lake Agassiz is one of fluctuating levels, punctuated by periods of relative lake-level stability.
		The lake began to form in the Red River Valley when the glacier retreated north of the drainage divide between the Hudson Bay and Mississippi River drainage basins; this is near Browns Valley, Minnesota.

	Louis Agassiz
		The son of a minister, Jean Louis Rodolphe Agassiz was born on May 28, 1807 in the village of Montier, in the French-speaking part of Switzerland.
		Agassiz labored for support of science in his adopted homeland; he and his colleagues urged the creation of a National Academy of Sciences, and Agassiz became a founding member in 1863.
		The cornerstone of Agassiz's biological thought was his belief that the gradation from low to high forms, in any taxon, paralleled the order of appearance in the fossil record, the order of stages in the organisms' development, and the distribution and ecology of the taxon.

		Lake Winnipeg is a northward draining, 400 km-long lake, situated in the former basin of glacial Lake Agassiz in southern Manitoba.
		Assuming open (overflowing) lakes with positive water budget, this would be expected to drive a progressive increase of lake area by southward transgression in sub-basins of the lake.
		Lake areas were modulated by diversion of Saskatchewan River into the lake about 4.7 ka, and by switching of Assiniboine River discharge between southern and northern basins and back about 7.5 ka and 4 ka or later.

		Glacial Lake Agassiz was a lake formed from the melting of glaciers during the Wisconsin period.
		The meltwater from Lake Agassiz was drained through River Warren which is now the valley for the Minnesota River.
		I titled this page "Lake Agassiz Returns" because the water was high enough at the south end of old Lake Agassiz that some of the meltwater started to breach the natural dam near Wheaton.

		The spatial extent of Lake Agassiz was controlled by an overall retreating, but fluctuating, northern ice margin, episodic switching of outlets, and isostatic rebound.
		The ice-contact lake margin is poorly constrained in time, but large moraines composed of sand and gravel record significant inputs of meltwater into the lake during deglaciation.
		Scour lakes within proximal ends of spillways are on, or adjacent to, sub-continental drainage divides, and contain important paleogeographic data.
