The most snowy university in the US knows how to celebrate winter in true scarfie style, writes Kate Roff.
For one snowy weekend in the dead of winter, a small university town in Michigan honours a beloved tradition almost 100 years old - Winter Carnival.
The powdered streets of Houghton and the campus paths of Michigan Technological University are cleared to make way for the carnival's famous statues - colossal endeavours of ice carving and snow sculpture.
Hosted by a group called the Blue Key Honor Society, the Winter Carnival celebration started with a simple dress-up evening in 1922 and has snowballed (excuse the pun) into a weekend of all-night revelry.
The festival boasts a Winter Carnival Queen contest, human dog-sled races, ice hockey games, ice skating shows and the ever-popular beard competition (facial hair is understandably desirable in such a cold climate). Students, locals and visitors don warm boots, scarves and ear muffs to brave the late-night February chills at the snowiest college in the US. With temperatures dropping to an average low of -12C (and even a record low of -31C) in the Houghton winters, the traditional outdoor "broomball" game (ice hockey in sneakers with duct-taped broomsticks) is not for the faint-hearted.
