SALT LAKE CITY, Aug. 31 (UPI) -- A fast-moving fire burned nearly 9,000 acres overnight in Utah's Pine Valley Mountain Wilderness Area, authorities said.
The fire, sparked by lightning July 25, had burned through 1,200 acres of mostly dead vegetation when it flared Saturday, the Salt Lake Tribune reported Monday.
"It came down (the) canyon like a fireball," New Harmony City Councilman Dellas Imlay told the Tribune.
As of late Sunday, at least three homes had been destroyed and about 170 residents evacuated amid forecasts of high winds, hot temperatures and low humidity, the Tribune said.
"The siding just melted off one of the damaged houses," said Dean Cox, Washington County emergency services director.
Smoke from the Mill Flat Fire could be seen throughout southwestern Utah, the Tribune reported.
