Later in the evening, I stopped by to listen to the Park Ranger at campfire chat. This was quite entertaining as he and the crowd (we) sang campfire songs and learned about the ecosystem of the park. An interesting factoid I found was that the Clark's nutcracker is responsible for all of the White Bark Pines and is the reason they grow at such high altitudes. The nutcracker harvests the pine seeds and stashes them away for winter. What he doesn't eat grows into new pine trees. The bird is the only means for the trees to disperse their seeds.
