Uinta National Forest Service officials say the fire that burned most of the steep mountain east of Mapleton over the weekend will be fully contained by Wednesday afternoon.
Forest Service spokeswoman Loyal Clark said the blaze that burned 2,950 acres and caused the evacuation of several southeast Mapleton homes was 90 percent contained as of Wednesday morning. Fourteen 20-person fire crews and five helicopters were still extinguishing hot spots and patches of fire on top of the mountain Wednesday morning."Depending on how things go today we'll start releasing firefighters Thursday and probably send most of them home Friday," Clark said.
Meanwhile, Clark said after three days of investigation fire experts have determined that the fire definitely began in a "6-foot-by-8-foot" section of land inside the Trojan Corp. explosives manufacturing plant near the mouth of Spanish Fork Canyon. Also, fire investigators have determined the fire was caused by an electrical problem, matches, ammunition or fireworks.
