The annual Winter Carnival at Michigan Technological University has been a tradition since 1922. These sculptures are not carved from a single block, but rather many blocks made over a month. For this reason, they can grow quite large (Up to the regulated 28 feet tall and sometimes over 80-123 feet long). Each year a theme is given for the winter carnival and the statues are created in the set theme. Student groups compete against each other in different divisions. Many U.S. states hold their own competitions with a national event being held in Lake Geneva, Wisconsin each year.
Frankenmuth, Michigan hosts a massive snow and ice sculpture festival in late January with teams traveling to carve from all over the globe. Frankenmuth's Snowfest consists many ice carving competitions and snow sculpting competitions in elementary, high school, state, national, and international levels.
