I went looking for more rocks with sharp edges and I found some more near the first one.
(I used the Waypoint feature of IASViewer to mark the rocks I found. Also, all the images are from the map-projected version, it is easier to relate
the images with the surrounding area this way)
All six rocks are on an relatively small area, marked here in red.
Rocks 1 (the original from the Opening Post) and 2 are near each other.
The other rocks are also near each other.
Seeing that both locations were near rocky outcrops, I went looking for more rocks near rough outcrops, but I could not find other rocks with sharp
edges and angles as the rocks from the previous photos.
But I did found two examples of how those sharp edged rocks may have been created, because I found two large rocks breaking along straight lines.
Photo PSP_001415_1875 is not the only photo taken by HiRISE of that area, photo PSP_005714_1875 also covers the eastern part (the one with the
"building") of photo PSP_001415_1875, as shown in the following images.
First, the same rocks from photo PSP_001415_1875, as seen on photo PSP_005714_1875.
Some rocks look a bit different because of the difference in the direction of the light, although the directions are not that different.
These are the rocks that I found on image PSP_005714_1875.
This first group in an area more to the east (nearer the rim of the crater).
Near the area from the first photo is where I found most of the sharp edged rocks. As these are a little too far apart to show in one image I decided
not to show the individual rocks, it would fill this post even more with images, but if anyone wants me to do it just say so.
This is the area where all these rocks can be found on photo
PSP_005714_1875
And this shows that this area is adjacent to the area of photo PSP_001415_1875 where the other rocks were found.
Considering the position of both groups and the fact that these photos are on eastern rim of Mojave crater, maybe there are other rocks like that on
other areas of the crater rim (or even on the crater floor), but that must wait for another opportunity.
PS: while looking for sharp edged rocks I have found two other things:
an area for those who like
rock tracks
(located here)
and a strange looking area that reminds me of pork ribs. Hmmm, ribs...
(located here)
In conclusion, I am even more convinced that this is just a rock, with an uncommon (in other areas, it looks relatively common in the two photos from
this crater's rim) shape.
Edit: I forgot to say that I used a value of 2.200 on the Wavelet Sharpening dialog, it makes the image look better.

Anything new at the Mission I need to know about? 
and you say I'm crazy
