Geology rocks

 We had to zip back to Guadix in search of a dentist for Jude. We've now travelled some roads in Spain more often than some in Rangiora... Anyway, Google lied about what was open but she did manage to find one. I spent the time at a market. It's surprising how many stalls sell the same shit. Free market economy I guess: prices will fall to a point that is stable for the number of stall holders.

Don't tell Jude

She knows about these though...

Then we went back to see what we had missed around the Megalithic Park.

First up were some travertine irrigation lines. These are formed the same way as Pumukale in Turkey, or the Pink and White terraces in NZ. Hot water dissolves chemicals that precipitate and build up as the water cools. Encourage them to flow in a certain direction and you get aquaducts.

Since this was all done in 33deg we rewarded ourselves with a swim at the warm water fed pools. Lovely.

That was a good three hours but we still had dolmens to see. But first a fascinating piece of geology: a discordance. You can see that rocks toward the bottom go up and down while further up they go sideways. An earlier fold has eroded then later sedimentary rock has formed in the expected horizontal layers.

The geologic layers are very evident here.

But now for some dolmens...

Many/most have had the lids removed and been looted.

The largest hasn't suffered this fate but had lost two side rocks instead

Note that this would all have been covered by a mound of earth.

Cool landscape so we we decided to see more of it.

(Above a somewhat out of order. We have parked up next to the dam.) 

There is doof-doof music playing somewhere even though we are in the middle of nowhere.
