"The woods are blue-gray and covered in lichen. He works methodically, as he has for several days. He uses only those materials already on the ground, nudging fallen wood into the growing design. Some branches he can haul in his arms. Some trunks yield to dragging and rolling, via rope and grappling hook. For other pieces, he needs a block and tackle, anchored to upright trees. Then there are the pieces to large for him to move. These must remain in place, dictating the design, its shape more discovered than invented."
