What Mounds Remain - Lizzard Mound State Park

With the “Effigy Mounds: Sacred Sites and Native Arts” program coming up tomorrow, Thursday, August 10, from 2 pm to 4 pm at Devil’s Lake State Park, I thought I’d try to wrangle out a timeline that might help “time-confused” folks like me better grasp where the mounds fit in the great gulf of history since the end of the last glaciers. Let’s have a look…

85,000 years ago: The Wisconsin Glaciation began in the late Pleistocene epoch.

15,000 years ago: An Ice front dammed the Wisconsin River at a point one mile east of present Lake Delton to form Glacial Lake Wisconsin.

14,000 years ago: The glacial dam breaks and the massive flood creates the sandstone features of the Wisconsin Dells.

12,000 years ago: Considered the end of the last Ice Age and Wisconsin Glaciation period.

11,000 years ago: Mammoths go extinct in North America

11,000 years ago: First groups of Native Americans begin migrating to Wisconsin (Near the Great Lakes.)

3,000 years ago (1,500 BCE): Widespread settlement begins in Wisconsin as glaciers fully recede

2,500 years ago: Earliest round/conical burial mounds built in Wisconsin

1,500 years ago (500 BCE): Construction begins on effigy mounds in the shapes of animals, birds, etc.

1,000 years ago: The Mississippian settlement at Aztalan, Wisconsin was founded around 1050-1100 CE during the expansion of the greater Cahokia-based Mississippian culture in North America.

500/600 years ago: The last effigy mounds are thought to have been built. (In the 1400s)

389 years ago: French explorer Jean Nicolet is believed to have been the first European to set foot in Wisconsin in 1634. He landed near Green Bay.

Today: Approximately 4,000 mounds remain from the original 15,000+ thought to have been created in Wisconsin.

**Note that all these periods and dates are estimates and different sources often have different dates, so take it for what it’s worth!! 😀
