CLUES:
- Many tourist sources incorrectly describe this site as featuring natural geysers caused by volcanic activity. The spouts actually are cold and man-made.
- Water rich with carbon dioxide, lime and iron flows from this site as it reaches the end of pipes installed for nearby mines.
- The dissolved lime and iron forms mounds up to 4 meters tall around the mouths of these artificial geysers. Metal from the dissolving pipes adds a rusty orange color.
- There are at least four — and by some reports five — of these cold-water geysers in this region, and they have become well-known tourist attractions.
