I was not really sure where to post this so here as a 'micro-landscape' (thanks Jim) ...
Taken at the Rio Tinto, Andalusia. This is a very special location: The water derives from old mine workings where sulfide minerals are oxidized by microorganisms to sulfuric acid. The river has in places a pH of 1.7-2.5 and as well as a lot of iron (hence the colour) contains cobalt, manganese and cadmium. No plants, no fish, no amphibians and insects die pretty soon after contact, which means that despite the near 40°C, wellies are 'a must' ... The only organic structures in the water are very fragile strands made by the microorganisms which are able to survive in these very extreme conditions. Fascinating to me as a chemist, the resulting reds, yellows, oranges and greens which glow intensely in the Spanish sun are a dream for a photographer ...
