This is quite a sight to behold. Both the Tetra and the other spires in the area are incredibly tall and narrow. Someone mentioned earlier that the Tetra might be an impression rather than a mountain, but I think this clearly shows that it's not an impression.
You need 3D glasses, but wow these are worth getting them for.
Is it artificial? I don't know, take a look at what Neil called the "Chevron Mark" at the top. It almost looks as if someone (or something) forced a huge wedge right at the top to split the mountain off into that shape. You can see the gouge.
hirise.lpl.arizona.edu/PSP_002841_1740
From the high-resolution JP2 anaglyph, set to 20% mag.
Same, set to 32%
The Chevron, from the full high-res JP2 Grayscale:
Note the gouge at the top of the left face (red arrow), scraping down into the top and right faces.

Many of these 3D images in my opinion seem suspect as to their concave/convex structure and I'm not getting sinister here, it's just that so many of the spires and other super pronounced mountainous ridges are out of proportion with respect to their sheer height vis-a-vis their base formation, so much so, in many instances the very top edge appears so thin, its hardly a wonder they could form that way.
So I decided to take a look at this "so-called" Tetrahedron close up in 3D and focus on the north "rim". Here's the location:

Here is a magnification at 1079 X 607 of the same quadrant:

What is quite clear here is the noticable shadow field to the left of the slight crests on the rim edge. This is NOT a protrusion but in fact is defined IMPRESSION.
Same magnification moved north:

<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">Yes, your posted 3D images appear to be impressions.
But if this is an impression, then nothing is real, NASA Jpl is a joke, and this whole thing is not worth the time we're putting into it.
This is a spire:
As I said, my image comes directly as is, from the JP2 Anaglyph downloaded from hirise.lpl.arizona.edu/PSP_002841_1740
I was trying to match up with precise lines, your image to mine, but was unable to. You drew a big circle on the grayscale image, but that doesn't help lining them up.

What I find somewhat amazing are these peaks and just how darn tall and shrap they are. There's something amiss here. In the image below ESP_013772_1795_ESP_022910_1795, I just clipped this from the HiRISE anaglyph and zoomed in and these puppies are everywhere. This is NOT a particularly good example of what I'm talking about...some are even more pronounced almost waffer thin!
NASA and JPL a joke. I don't think so but let's not forget the fact that we are looking at another planet and the ARE enigma's. This is what we are here for are we not?
