The is a portion of the Jessup Path in Acadia National Park. It is a neat area of marsh and transition trees. The birches are dying because the larger hardwoods are growing and blocking out the sun. This is natural. The area was burnt in a significant fire years ago and the birches grew quickly and now that the hardwoods have reached a more mature size the birches are losing out to them. The result for now is a neat landscape of white trunks and - in the fall - of a colorful canopy. Here the boardwalk is nearly a mile long and pretty straight. You can see, maybe, a group of people approaching deep in the trees on the boardwalk.
