Mars : The truth behind the Sand dunes.

The sand dunes on Mars, we all know them from the images that NASA shows us. But how do they arise anyway ? The shape of these dunes are often perfectly asymetrical. How come such forms to stand in an open flat landscape ? If there was something build, or there was a rock formation in the past, and the sand accumulates around them, then these forms are more explainable. And maybe that is exactly how they have formed. So, let us take a closer look at it.  Under the sand dune is mostly a part that doesn’t seem to belong there, and also the edges of the sand dunes are not like a sand dune should look like. The edges of these dunes should be smooth, but these edges consist perfectly triangular bricks, which are placed neatly side by side. Could this be old ruins? Buried underneath the sand ?
