Hi, RL!

Coordinates noted, thanks, RL. That part is clear to me now because I was questioning how the top areas of the Martian pic looked flatter when compared to the areas in the middle, etc. The shadows in the 'shoreline' area don't have to be shadows from a higher elevation line, they could also be made up of a different geo make up, thus the darker color. However, I can't stop thinking that the 'reflection' areas are reflections after all. Could the (mud)lake have frozen *convex* to 'that' shoreline? Is the shoreline on the opposite side higher? You would then get a reflection from both the reflective frozen 'lake' and the frost in the shoreline. On the original pic posted there is a definite shadow (not a reflection) there to the far right. If that pic was taken at that height and angle, then that must be a pretty high rock/glacier...

I know what you and Nathan mean. Perspective wise, Mars has been tricky. :)

Respectfully,

Marcia
