Visitors are being warned about the shoreline of Good Harbor Bay, part of the Sleeping Bear Dunes National Lakeshore, where officials say someone has spread glass shards across the beach.
Park officials say the glass appears to have been placed intentionally over roughly one hundred yards of the Bay shoreline.
Tom Ulrich is the Deputy Superintendent for the Sleeping Bear Dunes National Lakeshore. He said a similar incident occurred along the shoreline in 2017 just three miles from the current incident.
“Back when it happened in 2017 we thought it was a one-off but this is very disconcerting that it has happened again in the park.”
Ulrich said park staff are currently cleaning up the beach and have posted warning signs along the entrance.
He said the park is currently seeking information from anyone who might know who placed the glass.
“We would love to get information if anybody noted someone in this area acting strangely, breaking glass at home or something. We would love to catch the person who did this.”
Anyone with information about the incident is encouraged to call 231 326 4805
