A fresh, wind-whipped wildfire erupted near the southern border of Dugway Proving Ground late Wednesday morning, consuming 1,500 acres by evening.
"The wind really kicked up out there and it took off," Tooele County Sheriff’s Deputy Jeff Miller said Wednesday morning.
The blaze, dubbed the Pony Fire, was 40 percent contained by about 6 p.m..
The fire, on tinder-dry expanses of cheatgrass and juniper, was generally near the foot of Simpson Mountain and on Bureau of Land Management holdings along the southern border of Dugway, where crews on Monday had just doused a 5,000-acre blaze.
Paula Thomas, a spokeswoman for the Army facility, said officials learned of the fire just after 10 a.m. Wednesday.
"The fire is actively burning and spreading quickly," she said.
A cause was not immediately available.
No injuries or structural losses were reported.
Firefighters from Dugway, the town of Terra and the Bureau of Land Management were fighting the flames.
Five engines, two single-engine air tankers and four crews of 20 firefighters were on the scene, and two Blackhawk helicopters outfitted for sire suppression were assisting, according to UtahFireInfo.
