A lightning-sparked wildfire has destroyed 13 homes and threatens hundreds of others near a Utah resort town.

The blaze near Park City was among several in the West, where fires have devoured 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 about 10 miles outside Park City. It destroyed a dozen homes on Tuesday, plus another home overnight. Fire officials say it also burned 20 outbuildings and several vehicles and boats.

The fire has grown to more than 1,200 acres, or nearly 2 square miles. It is 5 percent contained. Two Black Hawk helicopters will be used to fight the fire Wednesday.
