Yellowstone National Park, August 30, 2019

This area burned during the 1988 fires. Lodgepole pine trees, which dominate the forest shown here, require intense heat to release their seeds and reproduce, meaning that burning is an essential part of their life cycle. The new trees shown here are all the same height, indicating that they sprouted around the same time after the fire. | Source: Renkin, Diane.
