While petrified sand dunes can be found in the American Southwest, these ones were spotted a little farther from home — on the lower slopes of Mount Sharp on Mars.

Captured in late August by NASA’s Curiosity rover, this image shows a layer of sandstone that researchers are calling the “Stimson unit.” It sits over a layer of mudstone, which was deposited there long ago in a “lake environment.”
NASA believes they formed much like petrified sand dunes on Earth, created by blowing winds and then cemented into rock.
