Prince George RCMP traced a series of blasts Monday night to work at a quarry off Otway Road.
The booms, which could be heard into the city's Bowl area, had sparked a flurry of calls to the detachment and by 8:30 p.m. police had begun their search.
By 10 p.m., they had found the source, the detachment said in a press release, adding there will be no further police involvement.
