On our recent drive to Estes Park, we drove through the Rocky Mountain National Park.
That's what is wrong in the first photo. The snow among the trees at the higher elevations shouldn't be visible. Those are evergreens, not decidious trees that haven't leafed out yet. Most of them are dead.
We saw the same thing at the Dillon dam, huge mountains covered with dead trees.
The Park Service has posted a recent article about the beetle problem.
