This is the bear cub who was gradually changing from being blond to being brown.
Here is a zoomed in view of her marking a tree. Female bears mark like crazy before they head for their winter dens. That fits with what the bear cub was doing over the past month!
Based on where she was marking, I suspect that she is in a den nearby, and that she's done with marking for the year. Sleep well, Bear Cub. We'll see you in the spring.
Here's a short video of her marking marking trees and other things. Enjoy! Soon, the forest will be quieter because these magnificent animals will be in their dens.
