In Nuevo Albergis there are many Puzzles , that have to be explained , I have seen many dunes , but not with shapes like these at Nuevo Albergis , What Wind conditions are needed to form these long dunes, and there are quite a few of them . They are very old and some of them cover even older Salt-Pans .The dunes are about 1.3 miles long and about 10 to 30 yards wide.
They must be wind dunes as there is no water there now.
This whole area was at some time well watered as we can
se by the thousands of Salt-Pans that are still visible after these centuries,
And now they are in the second largest desert in the world. With rainfall that is in millimeters a year.
