A lightning-sparked wildfire destroyed 13 homes and was threatening hundreds of others Wednesday near a Utah resort town. The fire near Park City was among several in the West, where fires have scorched dry grass and brush and burned to the edges of small communities in several states. Shifting winds in Utah pushed the fire toward homes in the Lake Rockport Estates subdivision roughly 16 kilometers outside Park City. It destroyed 12 homes Tuesday and another home overnight. According to fire officials, it also burned 20 outbuildings and several vehicles and boats. The fire has grown to over 5 square kilometers and was only fire percent contained Wednesday. Two Black Hawk helicopters will be used to fight the fire.
