Mars South Polar Layered Deposits

Remarkable layered deposits covering older, cratered surfaces near Mars' south pole dominate this mosaic of images collected by THEMIS between Nov. 8 and Nov. 26, 2003. The margin of these layered deposits appears to be eroding poleward, exposing a series of layers in the retreating cliff. The mosaic, created from eight VIS images, covers an area more than 325 kilometers (200 miles) long and 100 kilometers (62 miles) wide.
