A work barge and tug went aground on Lake Michigan in high winds and 8 foot waves near Glencoe, Illinois. The barge had run aground on a shoal some 100 yards offshore. When the tug tried to free the barge, it also ran aground. As both vessels began to take on water, the captain and 2 crewmen onboard were airlifted off by the Coast Guard. The tug was loaded with 3500 gallons of diesel fuel, but no pollution reported at the time.
