Katie Emmons, Erica Cushmore and Jenny Hall appropriately make the leap in the frozen Sloan Lake in Cheyenne, Wyo., wearing costumes from the movie “Frozen” January 11, 2015. They were taking part in the fourth-annual Matthew S. Schwartz Memorial Polar Plunge, which raised money for the Explosive Ordinance Disposal Warrior Foundation, a program that offers financial help to the families of EOD veterans who have been injured or killed in action.
