It is difficult to believe that 250 years ago the land that these trees inhabit was under a massive sheet of ice. In that time, the ice has retreated, pioneering plants have moved in to create soil, trees have taken root, grown over 100 feet tall, died and fallen over. Their decay will further promote the growth of other plants, including seedlings born from this toppled tree. Under the canopy of the forest is a lush carpet of moss. All of it is rich and green.
