Medicine Lake Wilderness
Medicine Lake Wilderness lies within the glacial drift prairie of northeastern Montana. The gentle rolling hills and numerous shallow wetland depressions were created by repeated advances and retreats of glaciers. More than 12,000 years ago, a one to three mile-wide valley bordered by pre- and postglacial terraces was formed by a glacial front along the ancient route of the Missouri River. Sitting at about 2,000 feet in elevation, Medicine Lake is a large, shallow lake which filled this ancient valley. The Medicine Lake Wilderness includes the main water body of the lake, the islands within the lake, and a portion of land southeast of the lake.
