Spiral tree stairs (hand tree)

Timber stairs about 21 m high spiralling up the hand-crown hero tree to its deck: 1.4 m treads on curved stringers, hugging the braided trunk low down on brackets, then sweeping out below the wrist on long log struts to arrive at a landing beside the deck's railing gap; a handrail on posts along the outside and along the inside where the flight leaves the trunk. Weathered grey timber. Made to fit tree_hand_twisted_hero_a and tree_deck_hand_a.
