BILLINGS, Mont. — Survivors of a tornado that tore into Montana's largest indoor arena and leveled several commercial buildings returned to a scene of devastation Monday — awe-struck that a twister so destructive caused no major injuries.
Under sunny, blue skies, owners of damaged businesses in Billings picked through the rubble of their storefronts, salvaging what they could from rain-soaked piles of debris.
Local officials said a 12,000-seat arena that suffered extensive damage would have to be gutted and, if there is structural damage, possibly razed.
But residents and local leaders said Billings got off surprisingly easy given the force of Sunday's twister, which snapped trees and power lines, lifted the roof off the Rimrock Auto Arena and left debris scattered across hundreds of acres.
The only reported injury was a homeowner who was hit in the head by a large hailstone.
'It would have been a disaster'
A day before the tornado hit, more than 7,000 people had been inside the Rimrock arena for an Indoor Football League game.
"The big guy was looking out after us," Yellowstone County Commissioner Bill Kennedy said. "If that thing had hit on a Saturday night, it would have been a disaster."
Witnesses and officials said the tornado carved through a commercial area, crossed a wide swath of unoccupied land and then stalled for 15 minutes or more over the arena before it dissipated.
It was the first large tornado to hit Billings in more than a half-century.
At the Bear Aces Casino, bartender Tracy Restad said she was out on the bar's front deck Sunday evening when she saw the funnel cloud start reaching for the ground

She and four patrons ran inside and huddled in the bathroom, where they were soon joined by five or six others from a nearby laundromat. Restad said she could not hear much as the storm passed over because a friend was praying in her ear.
After the building finally stopped shaking, they emerged to a landscape littered with broken telephone poles, merchandise from a nearby motorcycle shop and jagged shards of torn metal siding.
Restad was back on the scene Monday to retrieve her car, a Toyota Camry — now dented, splattered with debris and with its rear and side windows shattered.
"This is unreal," she said.
Touring the wreckage of the Rimrock arena, Gov. Brian Schweitzer warned that parts of the city remained dangerous if another storm passes through before debris is cleared. He signed an emergency declaration allowing Montana Army National Guard soldiers to secure the area.
Officials said damage would certainly total millions of dollars. Once the assessment is completed, the governor will decide whether to issue a disaster declaration that could open up the door to federal funding and small business administration loans.
U.S. Rep. Denny Rehberg said he would work to make sure the city and Yellowstone County get the federal assistance needed to help them recover.
Accompanying Schweitzer on Monday's tour, Rehberg said the destruction reminded him of a visit to the Iraq war zone soon after the 2003 fall of former Iraqi leader Saddam Hussein.Video: Caught on tape
"We don't have a lot of experience with tornados in Montana," he said. "The luck was that it was an isolated building and there is a lot of vacant land around it."
Besides the arena, the twister severely damaged a coin-operated laundry, dance studio, hair salon, marine and motorcycle shop and two small casinos. An auto glass shop was picked up by the winds and tossed into a nearby streambed.
Several other businesses had minor damage. Golf-ball sized hail that preceded the storm dented vehicles and shattered windows in nearby residential areas of the city.
