On day 3 we left the Eduardo Avaroa Reserve and headed north, passing through the Siloli Desert, until the limit of the Salar de Uyuni.
The desert of Siloli is characterized by particular strong winds that shape the surface at its will, including rock formations. That is why we could find there such exotic shapes of rocks, including the biggest attraction, the Arbol de Piedra ("tree of stone"). These shapes also made them super fun to climb them and appreciate the whole surroundings of the desert.
The presence of the corals proves that the area was once below sea level and it was then elevated until such high ground probably at the time when the Andes mountain range.
Some of these tomb chambers were now reopen by archaeologist for investigation and for the public. Inside we can still see the remains and its relics. Some of them have a clear skull deformation. The highborn Quechua applied tourniquets to their children's skull in order to create an oval form. It is not clear why they do this but one of the indirect reasons could be to mark a difference between them and the common people.
In the end of the day we finally reached the limit of the most expected Salar de Uyuni which we would visit the next day. We stayed in a Hotel de Sal, literally an hotel made of salt. Beds, tables benches, walls, all is made of salt! After a tasty bolivian lasagna made by Maura, we had another round of bolivian dice poker (which apparently is very popular) with our new Russian-Canadian and French friends.
