Take a look at the rocks in the upper left of these two images. Some of the rocks are clearly identical, albeit with sightly different lighting, but the rocks around them seem to be different in each picture.

To verify that these rocks are the same, look at the little white rocks that surround them in the foreground beneath them, and around them.

What happened to the bigger rocks around them?

Here we see a rock outcrop dubbed "Missoula," near Marias Pass on Mars.

My opinion is that aiming to demonstrate some pictures are fake is about as valuable as trying to verify that pictures are real.

Wiki:

In general, we at the Flat Earth Society do not lend much credibility to photographic evidence.

I understand that a "faked" image could contribute to the conspiracy argument but, really, if you wan't to dismiss photography as evidence then do so.  Don't just cherry pick.

The rocks are sitting in and on sand. Sand blows around in the wind. It's windy on Mars. The rover was shut down recently to wait out a big storm. 

The two pics were taken at different times, the wind blew the sand around between each picture.

End of.

If we're going to do this... it's also worth noting that the pictures were taken from different heights / angles.  So it's not entirely surprising that some rocks might be obscured from view.

..and also that PIA16239 is a mosaic assembled from a selection of smaller pictures, so it's perfectly reasonable that the sand shifted between these exposures, too ...

There are significant differences of the rocks and rock formations which appear around the two rocks in question in Image 1 and 2, yet the shape of the sand does not indicate any storm.

Yet there was a storm big enough to bury the rocks that appear in the OP?

In the full size images there are plenty of other discrepancies.

What 'shape' should it be?

Maybe. Maybe not. It seems reasonable enough to me. Can you prove otherwise?

Such as?

I took the liberty of marking the rocks and rock formations that seem to appear and disappear.

Green = Seen in both images
Red = Disappearing rocks

Tom Bishop, have you ever taken the subject of astronomy as well as physics seriously at any point in your life? It is very important to me that you know that Mars has sand storms that cover the planet very frequently. Also how does one become a member of the council?

[Tom Bishop]

Lets look at the big rock log that is connected to the left side of one of the rock formations.





Where did it go?

There are numerous issues with these scenes. Rock formations appear out of nowhere (see the top left red formation in this image)

Where did these rock formations go?

Where did the rock log in my previous post go?

And again, if we zoom in to the sandy peaks we can see that the sand formations near the copy-pasted rocks we can see that the sand appears undisturbed. It makes very specific shapes that appears in both images.

The vertically laid "rock log" on the left hand side of the yellow area that is connected to the rock formation is missing. Where did it go?

Are you being serious?  It's in the top left of your second image, just seen from a slightly different angle.

You don't get storms on Mars. The air pressure is too low ... 0.6% of earth's atmosphere reportedly. It would be like being breathed on by an asthmatic.
https://en.wikipedia.org/wiki/Atmosphere_of_Mars

Astronauts living on Mars, for instance, would struggle if caught outside in a fierce dust storm, where winds can reach 113kph (70mph).

70mph wind at 0.6% of earth's pressure? That wouldn't blow over a playing card pyramid.

F=ma.

Force = mass * acceleration.

The mass flow rate at such low pressures wouldn't even blow dust about.

You also are going to get less wind than on earth ... according to RET. There is no ocean / land mass temperature differential and Mars is a lot further from the sun. So much less heating and therefore energy to make wind. It is also a small planet unlike Jupiter, so less surface area to get wind up to speed - Wind on Jupiter won't stop, its dense and has lots of momentum. This is where the fairy tale starts to unravel. Tom's pictures only cement doubt on an already absurd claim made by NASA.

Rock log

EDIT: may have been hasty with the highlighter.  Will review on big monitor at home :-)

[Rama Set]

Thork is, of course, just asserting this. There is plenty of evidence for dust storms on Mars. Looks like a good opportunity for him to use his favorite mass-flow equation?

[Tumeni]

Where did it go?

Out of frame. It's the source of the shadow 1/3 - 1/2 way up the LHS of pic 2, isn't it?

[Tumeni]

If you superimpose the edges of pic 1 onto pic 2, it's clear that the two were taken from markedly different angles and (possibly) distances. Pic 2 doesn't contain the left-hand portion of pic 1, so this portion is out of frame on pic 2, taking your 'log rock' with it.
