The source of a loud boom that triggered a 911 call by a resident near Rocky Mountain House remains a mystery.
Clearwater County Regional Fire Rescue Services was alerted around 2:30 p.m. Thursday of a possible explosion near the town. The caller lived about six kilometres northeast of the community.
“After an extensive search and multiple agencies involved, we couldn’t find anything,” said regional fire chief Steve Debienne.
“It seemed to cover quite a widespread area. There were reports on Facebook that even up to Highway 12 (people were) hearing it.”
Numerous responders from a variety of agencies were called in to find the source of the noise, but they came up blank.
“We had drones in the area all over the place trying to see what was going on. But absolutely no dice; we couldn’t find anything,” he said. “We even utilized wildfire (staff) with their fire towers and they had seen nothing.
“It’s very unique and interesting,” he said.
“It’s alarming, but you can only search for so long. There were no reports of damage or injuries, so that’s the best sign we’ve got right there.”
