I found these bear claw marks on a lodgepole pine up a small drainage off of the Bannock Trail just outside the northeast part of the park. People say bears claw trees to communicate their presence (both male and female), and sometimes to take out their frustrations. Wonder how people know that.
You can tell the size of the bear by the width of the claw marks. I'm not sure how old these were (trees grow, increasing the spread and height of the marks).
Hopefully we will see some grizzly bears in March. The males come out first. Given the low snow levels and relatively mild temperatures we might see a bear this month!
