Another Martian dust devil. With a well defined shadow.

When this dust devil was spied in Amazonis Planitia on April 10th, the MOC was looking straight down. Usually when the camera is looking down the dust devil will appear as a circular, fuzzy patch with a straight shadow indicating its columnar shape. In this case, however, the dust devil is somewhat curved and kinked---its shape is best seen in the shadow it casts to the right.edit on 2/22/2011 by Phage because: (no reason given)

Yeah, you're right.
The images in the OP are probably CGI too.

You didn't read the caption for the image?
You want an identical dust devil image? Show me two snowflakes that are the same then get back to me. Until then, never mind.

What caused the streaks in this Martian crater? Since the above image shows streaks occurring both inside and outside the crater, they were surely created after the crater-causing impact. Newly formed trails like these presented researchers with a tantalizing martian mystery but have now been identified as likely the work of miniature wind vortices known to occur on the red planet - martian dust devils

What is 8 kilometers (5 miles) high, forms in the mid-afternoon, and cannot be found the next day? A Martian dust devil! The arrow in the left image (MOC2-141a, above) points to the tallest (8 km, 5 mi) of several dust devils spied by the Mars Global Surveyor MOC Wide Angle camera during its global geodesy campaign in May. The above two pictures (MOC2-141a and MOC2-141b, top row) are centered near 36°N, 159°W in northern Amazonis Planitia. Each image covers an area 88 kilometers (55 miles) across, and each shows similar features on the ground, such as the two partially-buried craters at the center left.
Central peaks – Peaks formed in the central area of the floor of a large crater. For larger craters (typically a few tens of kilometers in diameter) the excavated crater becomes so great that it collapses on itself. Collapse of the material back into the crater pushes up the mound that forms the central peak. At the same time, the rock beneath the crater rebounds, or bounces back up to add to the peak.

Oh come on. By no stretch of the imagination does a semi opaque object like a a dust devil create a crisp edged shadow like that. Even a solid object would create a shadow that gets more blurred the further it is from the object.
FAKE shadow.
