The Deer Creek Fire, which started in eastern Utah and has already destroyed several structures, has crossed the state line into Colorado, state fire officials said.

The Forsyth Fire, burning near Pine Valley in Washington County, grew another 775 acres, according to a July 11 update from the U.S. Forest Service. The spread occurred on the southern edge of the fire, where crews are focusing aircraft and ground efforts. Smoke also increased over the last 24 hours as winds pushed the fire into unburned fuel.
