Occurred on May 19, 2018 / Glacier National Park, Montana, USA
Info from Licensor: "We were on an overnight field trip with a group of kids to Glacier Park. While we were hiking to Avalanche Lake we encountered the sow and cubs. The kids had become spread out on the trail and when the Bears came over the ridge they were about halfway through our group. We had encountered the park ranger shortly before the interaction and when he heard us hollering at the bears he returned to our position and this video starts at about the time he got back luckily this came to a good safe ending."
