About this work
There is a circular feature in this observation from NASA Mars Reconnaissance Orbiter spacecraft that appears to stand above the surrounding terrain. This feature is probably an inverted crater that was filled in with sediment. The fill became indurated, or hardened, until it was more resistant to subsequent erosion than the surrounding material. Other craters in this image are not inverted or substantially infilled.
