The 1004 foot long, dwt 62335 bulk carrier Mesabi Miner collided with the 68 meter long, Coast Guard cutter Hollyhock near the Mackinac Bridge in the Straits of Mackinac. The Hollyhock was breaking ice with several lake freighters following behind with the Miner following astern of the icebreaker. When the Hollyhock hit an ice pressure ridge, it suddenly halted. The Mesabi Miner was unable to stop and struck the stern of the cutter. The cutter had significant damage to its stern and fantail while the Mesabi Miner sustained damage to its bow. The Mesabi Miner was freed later the same day by the assistance of cutters Biscayne Bay and Katmai Bay. The Hollyhock proceeded to St. Ignace aided by the cutter Biscayne Bay. The Mesabi Miner continued on its way to Gary, Indiana with its cargo of iron ore. No reports of injuries or pollution released.
