WAUPUN (WKOW) -- The deep freeze last week led to some ice quakes in Wisconsin, and now there is some visible damage from one of them.
Dennis Olsen of Waupun says he heard what sounded like an earthquake last Tuesday night.
Olsen didn't find any damage until the next morning, when his son and grandson found a long crack in the driveway, and they called the local sheriff's department.
"He didn't know if he should drive over it or not but he did, he said that happened to him east of here on a ledge a wider one about 8 foot deep," said Olsen.
Olsen estimates the crack is about 154 feet long, about 8 inches deep and 1 inch wide.
An ice quake happens when water freezes and expands in the soil and bedrock.
