Evacuated residents were allowed to return home Saturday night after firefighters fully contained the Hill Top Fire, while officials continue to feel the effects of the state's fire season. The fire, which started Aug. 6 from an unknown cause, displaced 350 residents and destroyed two structures at its peak. The evacuation order was lifted at 10 p.m. Saturday after officials fully contained the fire that consumed over 1,800 acres. After burning through more than 65,000 acres, 438 structures and costing more than $19 million to fight, fire investigators still do not know what caused the Dollar Ridge Fire early last month. "We get fires every year that we say are undetermined because there's not enough evidence, there's no witnesses and (they're burning) in a very remote area like this one is," said Jason Curry, spokesperson Utah Division of Forestry, Fire and State Lands.
