Layers in Terby Crater
This image shows a sequence of predominantly light-toned, layered, sedimentary rocks exposed by erosion on the floor of Terby Crater. Terby Crater is ~165 kilometers (~100 miles) in diameter. It's located on the northern rim of the Hellas impact basin in the southern hemisphere of Mars. The layered sequence is ~2 kilometers (~1.2 miles) thick and consists of many repetitive, relatively horizontal beds. The beds appear to be laterally continuous, which means you can identify a given layer in many locations across the area.
