re: The latest on "white Rock" of Pollack Crater
I'd like to see what the color imaging on Mars Express can make of White Rock, as well as other sedimentary structures such as this:
Light/dark boundary at W margin of light unit W of Schiaparelli
Alternating Light- and Dark-toned Layers in Holden Crater
White rock material in Gale Crater
Juventae Chasma--dark dunes and bright outcrop
