Quoting David Mann <[email protected]>:
Yes, the underground stuff is one of the reasons I want to visit. I'd definitely find the opal mines interesting as well. The night sky in such a remote place must be pretty good too. How do they keep the rooms from collapsing? None of the photos I've seen show any bracing.
The underground rooms are excavated into a pretty hard rock (closely compacted sandstone, I think). It's very structurally sound so doesn't seem to need additional support. The motel room we stayed in had been bored into the side of a hill, presumably by machine.
