After I compleated the Glies Track in the Watarrka National Park, and had a nice evening back in the Kings Canyon resort, I drove back south to Coober Pedy on July 3rd. I arrived there when it was already dark, but this time I decided to drive into the city to have a look for some underground motel or something like that. This first obvious thing I saw was a underground hotel. I stoped and walked in. There was a man at the reception but he said he cannot help me, he is just the driver. We start a little talk and it turned out, that I talked to Günther. He is originally from Stuttgart and moved to Australia many years ago. That was a lucky coincidence, because I was in the most expensive and luxurious hotel in the city. So because I met just the driver and not the receptionist, he send me to the backpacker in the town and told me what to do the next day. So I already had a good idea about what to do in the town and what to see there. I went to the backpackers Günther told me and booked a bed in a cave for the night. It was omfortably warm under the earth and dark, so I got a nice sleep. The next day I went around the city and did a underground tour. I got to know how opals developed and how the people there mine for them. I also saw some old fashioned and some new underground homes. Still 70% of the populations lives underground in Coober Pedy. The name comes from the aboriginal language of that reagion and means nothing else than white mens burrows. The people there start to live under the earth in lack of building material. And it is quite a good idea to do that. In the summer the temperature can climb up to 50° and in the winter in can drop to 0° during the nights. In the "dugouts" it is constantly about 23 degree. But still that is not the place I want to live.
