Photographer's Note

As I mentioned before, the sand dunes in the beautiful Deserto de Viana reach up to 50 meters. As much as there are of course higher dunes or mountains in the world, it is an incredible feeling when you stand next to a steep edge of a high dune. If you even subtly touch the sand edge, it slides down to the bottom. It is quite common for tourists to try sandboarding there. I am not sure how high was the dune which I am standing on in this photo, but because you can still see some sand pattern in the distant part of the image, I suppose a mathematician would be able to calculate the height by comparing the frequency of the sand waves at the top and at the bottom. You can get some idea about what is shown in this picture if you compare it with the bright area in my previous wider scene:

However, the dune became much steeper here in comparison to the bottom right fragment of the wider image. I will attach the same picture in natural colors as a workshop.

We were warned by the local guide to follow his exact trails while driving through the dunes. Just after we went to the top of this dune, we realized why it was important. The guide knew well where the edge of the dune is. We drove with a high speed to be able to climb the dune and then we had to make a sharp turn left and stop. If we would turn too late, we would jump off the very high dune, and I am not sure whether we would survive such a jump.
