mann, the reply 238 image SSI camera pointing was about Az 53, El -33. The LCL2-RAR2 synthetic false color 3D version is here with links to 3D animation of lighting changes in the area of interest.
Looks like the lines are the edges of very thin "plates" or layers of material. I'm sure the soil / rock guys can describe the geological micro processes that create such features.
Er, while you're at it soil / rock guys, how about an explanation of the micro-processes that produce circular soil patterns something like this.
And finally, for those who like to look a little up from the ground a couple of synthetic false color images here and here
These are parts of lighting change sequences with lots of missing data.
I don't plan to do any more in these sequences -- they're just too damn time comsuming aligning all the images.
Damn you, Red Baron.
