Occurred on February 22, 2025 / Grand Lake, Colorado, USA
Info from Licensor: "My husband and I went for a ride on our snowmobiles on the Grand Lake trail system (snowmobile capital of Colorado) and stopped for a lunch break on the edge of Gravel Mountain. While we were there, I pulled out my new gimbal to take a few videos of the scenery so I can get better at using the controls. A group of snowmobilers started riding to the top of Gravel Mountain one after another. It was a busy day on the trails but I've never seen so many riders up that high on Gravel Mountain. There were 4 at the peak at the time the slab broke and started the avalanche. We we were sitting at least 200-300 yards away from them so it was hard to see from the naked eye but the zoom on the screen helped and we could see that all the snowmobilers caught up in the slide were accounted for almost immediately. No one was seriously injured only minor scrapes and bruises and some damage to the sleds. The group of sleds at the bottom were friends and family of the guys who got caught in it. Some other people started to do a search to be certain no one was missing. We confirmed that everyone was accounted for before we left the scene."
