SUPERIOR, Wis. (AP) -- Warm weather may be to blame for the collapse of an ice sculpture in Superior.
The "Lake Superior Ice Project" was to have been the centerpiece of a Superior festival later this month. The sculpture was nearing its goal of 65 feet tall when it collapsed just after 10 a.m. Tuesday.
WDIO reports the structure fell straight down and did minimal damage to the equipment being used to form the sculpture.
Roger Hanson, who was hired by the city to build the sculpture on Barker's Island, said he will review his data to determine the exact cause of the failure. A statement from the city says warm weather in December and January may have weakened the structure's core.
