A lighthouse is covered in metre long icicles at the Grand Haven pier in Grand Haven, Michigan, USA with "Ice Pancakes" also spotted floating close by. The 1875 red wood frame structure which was moved to the end of breakwater in 1905 was covered in ice following a mixture of 2 weeks of sub-zero temperatures and spray from waves. Ice pancakes are a relatively rare phenomenon but have formed due to the polar vortex. Jim Swoboda, 62, who is retired in sales and marketing and lives at Grand Rapids, Michigan, USA said "The spray ice covering is the result of 2 weeks of sub zero temperatures across Michigan and much of the United States. Last week we had -26 temperatures. The icicle lengths range from a half a meter to several meters in length. You can see the wind swirl patterns in the ice high on the lighthouse." "On the water, ice as it is blown around in the waves create the patterns seen. It is called "Pancake Ice". We had a mild winter up until 5th February when we received a foot of snow which equaled all we had for the entire winter up till then." Please byline: Jim Swoboda/Solent News ?
