Gregg,

What is the scale of the Mars photo? i.e. - What are the dimensions of the squares?

Raised in N. Indiana farm country. Looks just like that in an ariel view!

Hi Mac,

It is 2.75 meters a pixel so that would make the ridges probaby between 1 and 5 meters wide. A wall like formation can be much darker and extend over only say half a pixel, and this will translate to a lighter pixel, so in these cases objects can be narrower than they appear.

Gregg,

Thanks. That is the walls. How about the dimensions of the squares?

AB,

Is that a guess or where did the information come from?

I have two additional questions.

1 - Is there any telemetry, shadows, etc., that gauge the height of the walls?

2 - Does anybody have a speculation as to a possible natural formation process?
