Homes were evacuated as responders continue to work on a fire near Highway 89 in Layton Sunday, Aug. 5, 2012.

LAYTON — Officials believe the Ridge Fire, which briefly forced the evacuation of about 30 homes over the weekend, was human caused.

Originally, it was reported that the fire may have been caused by lightning.

"We had no lightning, whatsoever," said Uinta-Wasatch-Cache National Forests spokeswoman Kathy Jo Pollock.

Although investigators don't know exactly how the fire started, Pollock said all other possibilities have been looked at and discounted.

As of 10 p.m. Sunday, the fire was 100 percent contained and was expected to be fully under control by Tuesday afternoon. The fire, which started just after 6 p.m. Saturday, burned less than 50 acres. But it threatened about 30 homes that had to be temporarily evacuated.
