Beartooth Mountains. 

Here, surviving about 8,000 feet, a tree now welcomes the change of / season, the white-bark pine. 

 

All summer these trees have been soaking up the energy of the sun, preparing for this moment. 

Now they offer the animals of Yellowstone a bumper² crop of pine cones³. The white-bark pine is gambling⁴ on the fact that animals now need all the food they can get before winter, and is hoping it can entice⁵ them to spread its seeds far and wide across Yellowstone. So inside the cones, it has put tasty nutritious⁶ pine nuts 

A pine squirrel.

It snacks on a few of the nuts to keep going, and then buries them one by one in a sheltered hollow beside the tree. If it hides them well and packs them carefully, they should last through the winter.
