Okay, I searched for a VERY long time, and could not find the images the OP found. I’m hoping that if the OP is still monitoring the thread they
will be able to provide the source data.
I did find another image, that I believe serves our purposes in this thread…
Comparable Image:
This image shows similar features on the surface of Mars, which also appear to the eye to be 3-dimensional objects at the peak of sand dunes. Lacking
the original image from the OP’s post, I’m hoping that this image will suffice for analysis, since the same anomalies appear.
The Image (and it’s companion data) is also located here, direct from Malin Space Science Systems (the guys who built and operate Mars Global
Surveyor):

Here is a link to the best version of the image from MSSS:

The above two images are processed images, and proper citation should be given to MSSS:

I won’t have time (or the equipment here at work) to do any zooming or analysis of this image until I get home tonight. Anyone who wants a head
start can use the above info, I look forward to your analysis.
I’ll do my best with this image this evening, and will post again once I’ve finished my examination.
