130316-G-ZZ999-001 USCGC Mackinaw breaks ice

Lights from the Coast Guard Cutter Mackinaw, a 240-foot Icebreaker homeported in Cheboygan, Mich., illuminate the ice pack off the fantail of the cutter as the cutter spends a night in Western Lake Superior off Duluth, Minn., March 16, 2013. The Mackinaw (WLBB-30) is the only U.S. heavy ice breaking resource assigned to the Great Lakes and in addition to heavy icebreaking other missions of the crew include servicing buoys, search and rescue, law enforcement, and the ability to deploy an oil skimming system to respond to oil spill situations.
