Not that I've ever jumped outta an operational plane to skydive, yet I would feel a wee bit more SAFE wearing a Parachute Pack IF I attempted such climb for the DESCENT. I've done like ZERO ROCK CLIMBING in WET weather. ...some people...
I'm slightly curious as to how many people joined their Spiritual Deities during construction, and since completion. There may have been some "handrails" (threads between sticks in holes) but like many of their local & mountainous "roads", the "handrails" have long since disappeared. "You climb with your Deity".
