U.S. Coast Guard Master Chief Petty Officer of the Coast Guard Phillip Waldron smiles during a discussion with members of the Coast Guard Station Duluth Aids to Navigation Team in Duluth, Minnesota, Dec. 15, 2025. Waldron spoke with the ANT team about things that were going well and any challenges they might be facing, as Operation Taconite, Coast Guard Sector Northern Great Lakes’s icebreaking mission, commenced the week prior due to cold weather conditions causing the waterways to freeze over earlier compared to recent years.
