The photo is from place called "La Laja," which is just northeast of San Juan. Long ago, this place was popular with tourists thanks to its hot springs. The area also was popular with mining, and lots of industrial activity blossomed in the area. The natural baths are still there and so is a beautiful stone hotel which was later transformed into a University museum.
The Jarillas is a small place with a population of only 13 homes located in the northwest of the Province of Cordoba, Argentina. It is a desert area, where there is very little rain, and because of this the land is so dry and brittle,that not grassland or vegetation can grow. On a hot day you can see lizards crossing the road and if you camp you will also come across many of them. You may also see tarantulas, but very different from those living in hot and humid areas, these are "more colorful with velvety colors" instead, the others in the area I'm talking about are black and hairless. They say they are not dangerous but I always approach with caution...
