Glacial Lake Wisconsin was a prehistoric proglacial lake that existed from approximately 18,000 to 14,000 years ago, at the end of the last ice age. Before the last glacier, a somewhat different Wisconsin River drained the north-central part of the state, running around the east end of the Baraboo Hills.
