Coober Pedy - weird

On the 17 day we went to a pretty cool camp site and in the morning we went to underground houses and to underground opal mine's we went to underground churches next we went to the underground opal mine. Everything like houses churches they are all underground because in summer it gets to about 50 degrees and when it is that hot outside it is 26 degrees inside all year round even when it is 0 degrees.

We did our own noodling noodling is mining for opals and we found our own opals it looks like someone put sparkles in the opals.
