Strange small hard balls of debris have been found on a Lake Superior beach. It may be the first time this phenomenon has washed up in the Great Lakes.
They’re the same phenomena as what are called “whale burps” or “surf balls” on ocean beaches. But this time the little bundles of debris were found on a Lake Superior beach in Duluth. Minnesota Sea Grant’s Sharon Moen says they’re a mix of nature and litter balled together by wind and lake."
