Wonewac in Juneau County, Wisconsin — The American Midwest (Great Lakes)
Geology of the 400 Trail
Glacial Lake and Sandstone Bluffs
The large sandstone outcrop seen beyond this sign is known locally as the "Third Castle." It stood as an island in Glacial Lake Wisconsin. The name "Castle" comes from the fact that these rock bluffs reminded European settlers of the walls of castles from their homelands. First and second castle are located to the left but are not clearly visible from here. The castles are on private property so can only be enjoyed from this view.
The area north of Third Castle is shaded most of the day. This creates a cool climate where hemlock trees, normally found farther north, can grow in the cliff’s shade.

Also see . . . Glacial Lake Wisconsin (Wikipedia). Around 18,000 years ago, the Green Bay lobe of the Laurentide ice sheet crept in from the east, butting up against the Baraboo Hills. With that outlet closed, the water backed up, filling the basin to the north and west, forming Glacial Lake Wisconsin. The water rose to as deep as 160 feet, with a surface area eight times the size of modern Lake Winnebago. (Submitted on October 27, 2020, by Cosmos Mariner of Cape Canaveral, Florida.)
