Today’s Image of the Day comes from the NASA Earth Observatory and features a look at the Samalayuca sand dunes located in northern Mexico.

These sand dunes are the remains of an ancient lake the dried up after the end of the Pleistocene Epoch. The sand is almost pure silica that had been deposited by the Rio Grande river and has since been pushed eastward by wind.

This image was captured by the Operational Land Imager (OLI) on board the Landsat 8 satellite.
