Captain Kim Alfastsen guides the M/S Tennessee through the 20-to-25 cm thick ice in Horsens Fjord, Denmark, Thursday Dec. 23, 2010. Tennessee is a combined tug and icebreaker of 100 tons, with a 550 BHP engine and a reinforced hull. It has three tons of lead at the aft of the boat, which helps lift the front end up on the ice. A night storm dumped up to 15 cm of snows across Denmark, hampering road, rail, and air traffic. Worst hit was the Baltic Sea island of Bornholm, where police urged people to stay indoors. In the south, the Danish army mobilized armored personnel carriers to help ambulances and other emergency vehicles get through.
