Produce a detailed written description of a depressing scene in the woods with a great oak, cracks, landing, and a tree.

Shaped from the once-living wood of the tree, the landing extends outward from an arch-shaped opening in the side of a great oak. The bark of the tree itself has turned a sickly grey hue, and numerous thin cracks mar its surface. Once sturdy branches have begun to lose their strength, bending low toward the ground some forty feet below.
