Layered Deposits in Terby Crater
October 12, 2009
This somewhat cloudy THEMIS visible image shows a stunning example of layered deposits in Terby crater, just north of the Hellas impact basin. Some researchers argue that layered terrain in craters were deposited by water. However, in some places, layered deposits will extend for up to a kilometer above the crater rim, leading others to conclude that they must be volcanic airfall deposits.
