Occurred on May 9, 2023 / Charlo, Montana, USA
Info from Licensor: "I took this video from my living room window on our Montana cattle ranch, Diamond H Livestock in Charlo, Montana. An active thunderstorm was rolling across our Mission Valley and my family came into the house while it passed. We were looking outside for lightening strike and noticed the funnel on the mountain. I grabbed my phone for some video and photos because we were astonished at what we were seeing. As we watched snow was being pulled up into the funnel from the mountaintop. The funnel was on the mountaintop for about 8 minutes and clearly advanced eastward before it finally began to dissipate from the bottom up. The mountains are located in Western Montana and is the Mission Mountain Range. The funnel was nearest to the town of Saint Ignatius where it reportedly destroyed a barn before moving up the mountain and starting east over the mountain range. This was an amazing sight and I was lucky to capture video of the twister while it was on the mountaintop!"
