On the final day of our tour, we headed towards our destination town of Uyuni. As we approached the edge of the salt flat we came across miners chipping blocks out of the surface and grinding the salt down into pieces that could be loaded into trucks for processing into ordinary table salt. Here we also came across places where underground water would seep up to the surface in brownish pools that the locals called the eyes of salt. If you stuck your arm in one of these pools, it would be covered with salt crystals as the water drained off and evaporated.

Once we arrived in Uyuni itself, the tour was pretty much finished, except for one final stop to an old train graveyard.  Apparently Uyuni had been quite the railroad hub back in its heyday, but now all the old locomotives had been condemned to the desert, slowly rusting away and being used as a playground by the local kids.
