When you first walk into the cabin, you can't help but notice a tree in the midst of the space with stairs growing out of it. The tree, a ironwood, was leaning and threatening a power line when Chuck spotted it. He rescued it and it has become the focal point of the cabin. The stair treads are made of lumber reclaimed from a nearby furniture factory. Snowshoes, apple limbs, and other interesting things have made their way into the spiral staircase. You'll have to count the number of spirals the ironwood makes from roots to tip.
