In a Wednesday, Jan. 3, 2018 photo, a float of 18 ice blocks and two Wee Kut Ice workers drifts in Green Lake, Minn., as ice is swept before being scored and separated near Spicer, Minn., on Wednesday, Jan. 3, 2018. The ice on Green Lake is about 16 inches thick, and the floating blocks are held together by the bottom four inches after being scored. The blocks will be used to build the ice palace for the St. Paul Winter Carnival later this month. (Evan Frost/Minnesota Public Radio via AP)
