Iceman, I admire your search for anomalies, and I am glad to see you stand up for what you believe. It is good to discuss things, even differences in opinion, because the more we struggle with an issue, the more each of us learn, and the stronger we all become. And let's face it, there are not many of us willing to pull raw images and search for details.
This is my opinion on the subject; please take it for what it's worth. It is offered in friendship:
You have to be careful about adding contrast, particularly to grayscale images, because it can produce things that look artificial that are not. Black things become blacker and white things become whiter. And in the process the true detail is lost. This creates extremes in an image that do not exist in reality.
You also should consider the fact that the image you are working with is the L6 filtered image. This is basically an image taken with a blue filter covering the lens. All of the blue color (matching that filter) is screened out of the shot - so it is an incomplete set of details that you are beginning with.
A color image contains more detail because what is screened out in one filter is added back in with another filter - at least once you combine a full set to approximate RGB. The image I've put up above combines the details from three different filtered images.
Our eyes can see a huge range of detail in color that we simply can not see in grayscale. NASA knows this, and they talk about it in their remote sensing manual:
"Another essential ingredient in most remote sensing images is color. While variations in black and white imagery can be very informative, and were the norm in the earlier aerial photographs, the number of different gray tones that the eye can separate is limited to about 20-30 steps (out of a maximum of ~200) on a contrast scale. On the other hand, the eye can distinguish 20,000 or more color tints, so we can discern small but often important variations within the target materials or classes can be discerned. Liberal use of color in the illustrations found throughout the tutorial takes advantage of this capability; unlike most textbooks, in which color is restricted owing to costs. For a comprehensive review of how the human eye functions to perceive gray and color levels, consult Chapter 2 in Drury, S.A., Image Interpretation in Geology, 1987, Allen & Unwin."
The vast weight of all of the pictures released by NASA are grayscale or brown, near monotone images. Why do they do that knowing that there is nearly 1000 times more information available to the human eye in a color image? That is for them to answer, not me. Humans are simply not able to pick out detail from these images. And so in order to see detail, and show true detail to our friends, our goal should be to produce the widest array of color we can produce from a given set. Sometimes that's not possible when they only give us a single grayscale image, but sometimes it is.
Here is an extreme example of how adding too much contrast (changing all of the gray tones to either black or white) can produce an anomaly that is not really there:
Is this the vid you are talking about? There are giant crystals in Mexico that are as tall as houses and far thicker than a man. They have been found underground so these could easily be those type of thing with just the top poking out. Some people say they are a power generator of some kind.
I too think it is the top of an obelisk. I have seen crystals for sale with this structure too so it maybe a natural crystal formation for some kind of quartz (or something).
Now for the fun, and for me to show why I was so excited to see this discovery.
This object Chandre found in sol 585 is not one-of-a-kind.Â
There are several other blocks(?) that have a similar A-frame shape:
Sol 66:
Sol 88:
Sol 97:
Sol 582, also with a large rectilinear slab nearby. (Is this possibly the same object found by Chandre 3 sols later in sol 585 or is it completely different?) (Look at the ground in the upper right - the rocks form a rectilinear pattern around an empty area - could this have been the curtilage surrounding an ancient habitation?)
Hi guys .. I dont expect you to believe me but there seems to be a very large something /craft  in mid section of pic... Its pretty well hidden. Entire mid section dune system is false..
Harry
Nice find on Structures

i think that simply one of the 2 images must be a fake.
the clear geometrical and perfect shape of the pyramidal dark object can't be due to a joke of lights and shadows ( at that distance, we can exclude the famigerated "pixel artifacts" ). so we have 2 possibilities
1. fake ; the dark puramidal object is a fake done for some reasons ( we can imagine em with a little of effort ).
2.real ; the dark pyramidal object is real, and for some reason it has been subject to tampering only in one image for some kind of misunderstandig. once published they can't went back, tha damage was done.
Xenon, thats a brilliant find ,the second pyramid has made me think of a line of pillars and a structure now buried under the sand where you can just see outlines. Having been to some of the more obscure excavations in Egypt I can tell you that this is what the monuments look like when they are first discovered. I could pull images to prove this but I hope you can all trust me on that point. The second pyramid appear to be the same as the first just covered with sand. I think the perception of in/out is due to the lighting in the images and the pattern of the way the sand has been blown around them (maybe by a small dust devil ?). ARP2, you need to look at more images and see if you can identify any more submerged linear structures and a possible line of pillars ?
Having had another look at the pyramid, I am left confused.....It looks like it has entered the dune/snow, in an upward motion.
The other dark object to the left also looks like it has entered the dune/snow, but in a downward motion, now this may just be a trick of the image, but I don't think so.
What do other members think ?

The pyramidal shape has a structure beneath it, in fact there is another pyramid shape to the bottom left of the image. plus there are several Anomalies throughout the Sol 585 pan cam images.... Here
very good find Chandre

Hi ARP2, I've been working over the images which is why I haven't replied. I've picked up two other areas that could be anomalies that may be connected to the object. Please excuse the sloppy lines, I am working on a laptop and battle with the Synaptics device Area 1, there is a 'rock' jutting out of the sand that has a wonderful reflective surface (it reminds me of obsidian or a crystal) and is a perfectly shaped pyramid (like the top of an obelisk) Area 2, there is something under the sand here that looks like a block
Highlight of the top edges of the block in the the second image, notice how the pyramid is blurred in this image and appears to be part of the block. I think your anomaly may be part of the block but is definitely worth some more investigation of these images and maybe the sol before and after to see if you get a different angle ?
This is a really good find, as the object seems native to the surrounding geological terrain, my first thought was to a crashed booster rocket more so in the second image, but there has not been any boosters used in the martial arena (none that I know of), it is more reflective than surrounding rocks and seems cylindrical in shape more so with the shape of its shadow, I just wish we had better quality to work with.

ps looking to ARP?s images the object seems to be slightly deformed, in the sense that the ciclindric shape isn't perfect. as the image of ARP's seems to be better in quality than mine there are chances that the effect i reached is a distortion. in this case the "hole" at the end of the object could be simply its shadow. its shape is at the end not impossible for a stone.
the object seems to have a sort of circle-hole at the end. its shape seems in effect to be cilincric and well smoothed. if i imagine this image comes from the earth, i would say it's a mechanical piece of something deattached...i think it can be an anomaly.
I don't know what the "cylindrical in shape" thing is, but it definitely looks out of place. Of course it could be just another stone....but it's half buried, rectangular and lighter in color...ahh I wish we had a better quality photo available
Hi, I found this anomalous object in Spirit Pan Cam 585. It looks a bit cylindrical in shape... This time I'm remembering to include the link! I have highlighted the object with red arrows... What is it, in your opinion??? Thanks, ARP2
