GREAT FALLS – It’s a calm Thursday evening in Great Falls after an explosion and fire at the Calumet refinery.

Witness reactions flooded social media with firsthand accounts calling the immediate aftermath chaotic.
Ryan Johannesen was working at Mountain View Co-Op directly across the road from the refinery when he felt the explosion.
“It felt like there was an earthquake in the building,” he said. “The windows were rattling and stuff and I looked up and there were flames probably eighty feet in the air.”
Johannesen said he was afraid for the safety of anyone who might have been near the explosion.
“It scared me. I mean, that’s a pretty close call. It could have been a lot worse with the two gas stations. I’m just glad nobody got hurt,” he said.
Dawn Wood, owner of HCL Equipment and Country Boys Welding located along Old Havre Highway, told MTN News she was talking to her employees when they heard a loud boom.
“My front door, my office door, opened and closed and my dog started barking so I went out and I was looking,” she said. “I thought somebody hit my building with the car, but it wasn’t. I seen the smoke and the fire coming from the refinery and I was like, ‘Oh my god, the refinery’s exploded.’ I was terrified because I know what they make there.”
