(Undated) -- The 2013 NCAA Women's Ice Hockey Frozen Four is being held at the University of Minnesota Ridder Arena later this month. The event has now been declared a sellout. The host facility seats 3400 and will be full for the tourney. The Golden Gophers are ranked No. 1 and in the midst of an unbeaten season. They could finish an historic season on their home ice. The Frozen Four runs from March 22-24.
