171 treeing spring cubs

July 1, 2019 Brooks Camp, Katmai National Park, Alaska. Sow 171 treed her cubs outside of employee housing in Brooks Camp due to a sub-adult bear following her. This was in the evening and employees were coming home from work. I paused videoing for a minute to yell to people to go around the long way so as to avoid her, which they did, but she did go to investigate. After, she seemed much more calm not seeing the other bear, so she called her cubs back down and wandered off. Just a couple minutes later, though, the other bear walked by, following her again. It's a young bear and probably not much of a threat to her cubs, but a mother can never be too safe, which is why mother bears will tree their cubs fairly often, both to get them away from danger and also to wrangle them into a single spot so the mom can get some "work done" like fishing.
