They are vast smoke plumes1. Yellowstone is burning. Throughout the summer, the dry lodgepole pines have become like a tinderbox, and lightening has struck the match. The worst wild fires will burn for weeks. In 1988, a third of Yellowstone burnt in a single summer. Devastation2.

fertilize3 the soil, and fire opens it up to sunlight. As the forests
