VIDEO: The Goose Point Fire has grown to an estimated 3,000 acres Thursday morning, and there is no containment so far.
Fire officials used heavy machinery to create a break between the fire and 15 homes. There are no evacuations as of Thursday morning.
The wildfire broke out Wednesday evening on West Mountain, near the southeast corner of Utah Lake and west of Spanish Fork.
Crews worked to protect the Brigham Young University Observatory at the top of the mountain.
The fire started on the west side of the mountain and spread uphill toward the observatory, according to Payson Fire and Rescue.
No injuries or damage have been reported so far.
