Coober Pedy

---

What an amazing place. Much of Coober Pedy is underground, so of course we had to stay in a motel where our room was carved out of solid rock . . . I never dreamed I’d have claustrophobia after the summers during university I taught caving, but with only a 150 mm (6”) vertical pipe venting the room to the outside 20 metres (60 feet) above, it has been a real struggle convincing myself I can still breath okay. Really interesting displays on opal mining. Learned the difference between a doublet and a triplet (both are just thin slices of opal glued to a backing, the latter with a clear crystal outer layer)
