We encountered a bear at a lodge last summer, in a tree outside our lodge window, three stories up. The next morning we went outside to see where she climbed up the tree, and this is what we saw. A bear can climb up a tree in a few seconds, we saw her do this. And down as quietly as you would wear soft slippers....be aware of that when you are walking in the forest! You see these marks, you are in their zone!
It was actually a lot of fun, from our side of the glass I should say!
