Two groups of ice fishermen, 10 individuals in all, have been given the greatest day-after Christmas presents it is possible to receive — their lives. The anglers, in two groups of five each, were stranded on ice floes that pulled away from the west shore of Chequamegon Bay and began drifting in the direction of Long Island. According to City of Ashland Fire Captain Scott Thimm, the department was notified at 8:29 a.m. Monday by members of one ice-fishing party that they had been stranded on the ice. The ice thickness had been reported as between four and six inches of blue ice, which in ordinary circumstances is thick enough to support the weight of a human being.
