Shallow grooves created by the internal movement of this body are evinced by "beaded shelterbelts," which are areas in which belts of trees are taller or shorter depending on local soil effects. Landforms called "differential compaction ridges" were created by this body's constant refilling. Kennett and Firestone proposed the "Clovis comet hypothesis" in opposition to a theory that states that this body's drainage into the Atlantic likely resulted in a major stadial known as the Younger Dryas. This body's main outflow channel carved the Traverse Gap near Big Stone Lake, and spilled over a giant waterfall that receded to form St. Anthony Falls. Its waters exited via River Warren and the St. Lawrence River. For 10 points, name this body of water that, during the end of the last glacial period, covered most of Manitoba and parts of Saskatchewan and Minnesota, named for the Swiss glaciologist Louis.
