[2] Muskallonge Lake was created during the retreat of the Laurentide Ice Sheet, some 6,000 to 4,000 years ago.

Since that time, it has been cut off from Lake Superior by a strip of land averaging one quarter of one mile wide.

The surface sediments in the area of the lake consist of glacial drift made up clay, silt, sand, and gravel.

[2] During the 19th century, the lake was used as a mill pond for white pine logs brought by narrow gauge railroad lines to feed the sawmill at the town of Deer Park.

[3] Remnants of its lumbering days are seen in partly submerged logs found in the lake.
