Light-toned Layers West of Juventae Chasma

November 4, 2008
A pit on the floor of a trough west of Juventae Chasma exposes a concentric, laterally continuous, light- and intermediate-toned layered deposit that is eroding to form knobs and ridges.

The walls of the trough—also exhibiting layering consisting of darker, thicker and blockier material—are shedding boulder-sized blocks down the slopes. The surface of the higher, surrounding plains also shows evidence of light-toned layering that is exposed beneath an eroding intermediate-toned, scabby surface.
