This graphic shows the locations of the southern edges of the glacial sheets and glacial lakes that covered much of north central Montana 100,000+ years ago. The map also shows the present-day route of the Milk (dots) and Missouri (dashes) Rivers. The pre-glacial route of the Missouri River was around the north edge of the Bear Paws and through Blaine County along a channel now occupied by the Milk River.
