This image is of the upper part of Athabasca Valles, a very young flood channel on Mars that might have been carved by a flood of lava instead of a flood of water. Of course, “very young” is a relative term: the flood that carved the channel took place millions, perhaps tens of millions of years ago. Erosion has dug into the upstream sides of the high-standing parts of the landscape and produced boat-like tails on the downstream side.
