The University of Wisconsin-Madison has found a new and innovative way to combat racism in the United States: by removing giant boulders from its campus.

Last week, the school assembled a crew to hoist the 70-ton rock known as Chamberlin Rock and ship it down to Lake Kegonsa, just south of its Madison campus. The historic boulder, which dates back to the Precambrian Era and is likely more than 2 billion years old, had become a source of controversy on campus after some students claimed it was racist.
