Updated Jan. 15, 2019: As of Saturday National Park maintenance workers have begun plowing and picking up trash.
While many federal employees continue to be out of work during the partial government shutdown, about 30 volunteers are filling in for park rangers at Sleeping Bear Dunes National Lakeshore.
Members of the non-profit group Friends of Sleeping Bear Dunes have emptied trash receptacles, cleaned and restocked bathrooms, and groomed 20 miles of trails around the Lakeshore.
