Agassiz Wilderness was created in 1976.

Lake Agassiz was a glacial lake located in the center of North America around 30,000 to 10,000 years ago. It drained over the years, including one massive breakout that caused a mini Ice age to start, and the lake to refill. Much of the final drainage of the huge lake is thought to have occured in a very short time, with various theories that it caused a one meter rise in sea levels, and that is where the various flood myths of early cultures, including the Biblical flood, comes from.

Parts of the lake still exist today, Lake Winnipeg, Lake Winnipegosis, Lake Manitoba, and Lake of the Woods, and others, are said to be relics of this ancient lake.

Louis Agassiz was born on May 28, 1807.
