The climate of the region is arid and has a clear time-of-day climate, in which the mean daily temperature fluctuations are greater than the temperature fluctuations over the course of the year.
The mean annual temperature of the region is around 7 ° C due to the altitude, around 4 ° C lower than in Atocha (see climate diagram Atocha), with a monthly average of 2 ° C in June / July and 9 ° C from November to March.

The city of Uyuni is connected to the city of Tupiza by the 197-kilometer Ruta 21 , which runs about halfway through Atocha .

In addition, the villages are only a few kilometers apart. Assignment difficulties and errors on the part of the various collectors and researchers cannot be ruled out. When labeling the mineral samples or in the lists of scientific literatures, the simplified description of the location of the “Chocaya Animas” pit is often found.
