I was there in about 1970 and hiked down to the drilling rig in the center. Went back about 1984 and by then they had stopped allowing non employees to climb down in. Apparently some lady tried it in heels and their insurance company said 'no more'. Have they begun allowing people back down since then? It seemed to me that a stairway wouldn't have been that hard to install. No trouble downloading it but had to use something other than my browser to view it.
