U.S. Coast Guard Petty Officer 1st Class Collin Wright, a Boatwain’s Mate onboard USCGC Mackinaw (WLBB 30) transits the pier as buoys are unloaded while moored in Milwaukee, Nov. 30, 2022. These large seasonal buoys are replaced with thinner buoys that can withstand build-up from ice as the Great Lakes freeze over in the winter months.
