 "Hollyhock" is designed as a multi-mission vessel, with its missions being aids to navigation, icebreaking, search and rescue, law enforcement, and marine environmental protection.Today, the Juniper tenders conduct almost as much law enforcement as aid to navigation work.On the morning of January 5, 2014 "Hollyhock" was breaking ice for the lake freighter "Mesabi Miner" approximately 22 nautical miles west of the Straits of Mackinac.
