Daryl,

As has been suggested, what you are seeing is probably where bears have been feeding on the cambium layer under the bark of the trees. If they have completely torn the bark away from the tree, sometimes even girdling it, this is the case. This is why timber companies in certain areas of the Pacific northwest hate bears. The bears girdle the trees and kill them. They (timber companies and biologists) are experimenting with suplimental feeding of the bears in problem areas to discourage this type of damage.

Bear markers are something else entirely. The bear that made this mark is the "he bear" of this mountain!
