Officials believe the Knolls Fire, which has burned nearly 13,000 acres and forced thousands of Saratoga Springs residents to evacuate, was human-caused.
It's unknown what exactly caused the fire to spark or who is responsible. The investigation is still active and ongoing, Utah Fire Info announced on Monday. Officials say they have ruled out lightning as a cause.
The flames sparked on Sunday afternoon at approximately 1 p.m. when winds were up to 57 miles-per-hour. The blaze quickly spread toward nearby neighborhoods. More than 13,000 people were asked to evacuate their homes and seek shelter elsewhere.
As many as 250 people were on the fire line, and are expected to be working the blaze for the next few days.
Evacuation orders were lifted on Monday afternoon as crews were able to get a handle on the flames.
Rain combined with cooler temperatures helped crews reach 31% containment on Tuesday morning. As of 7:30 p.m. Tuesday, authorities reported the fire was 75% contained.
So far, 12 homes and nine properties have been damaged and one home, a shed and 18 fences were destroyed, according to officials.
Authorities are asking those who do not live in the area to stay away because there are still a chance for flare-ups.
Sandbags are being distributing sandbags to help prevent flooding.
Highway 68 and Redwood Road are still closed south from Harbor Park Way.
Bureau of Land Management lands in and around the fire perimeter are closed to access until further notice.
