Residents of at least 1,500 homes in northern Utah are being evacuated after high winds kicked up a fire started by target shooters.
The roughly 4,000-acre blaze started Thursday near Saratoga Springs, about 40 miles south of Salt Lake City.
Fire officials are calling in additional aircraft and extra ground crews.
Bureau of Land Management officials say this is the 20th target-shooting related fire this year in Utah.
The Utah County sheriff says he's afraid the fire could take down the area's power grid, shutting off electricity to up to 7,000 homes.
A continued mix of hot, windy and extremely dry conditions has raised the fire danger across Utah and parts of Wyoming, Arizona, Nevada and Colorado.
At a wildfire burning over 68,000 acres in northern Colorado, some homes are being evacuated because of several spot fires started by winds outside the main fire. The High Park Fire burning west of Fort Collins has now destroyed at least 191 homes. It's also blamed for the death of a woman whose body was found at her ranch.
