Hey Internos! how are you doing? good finds as usual! What do you make of pic #3? Is that a breach in the ground or a side of a cliff?

Internos is really going berserk with those excellent images!!
OK, here’s an image of Mars, taken by Mars Express, of Kasei valles (North). I’ve enlarged an area south east of the image that resembles the famous ‘Inca City’ on Mars. And the resemblance is uncanny!
Cheers!

Hey Rohn! Nice pic! Have you got another one of the same area with better res? That would be helpful. Personally I think those 90 deg verticals on the left of the iimage is a photographic glitch. But the 'tracks' going into the crater are pretty interesting!
Cheers!
The "Inca City" ridges occur in a topographic low within eroded, layered deposits in the south polar region. The ridges appear to have once been covered by these same layered materials, but were subsequently exhumed by wind erosion. Possible interpretations that have been offered to explain the ridges include the following: (a) ancient sand dunes that became buried by polar ice and dust deposits and were lithified (cemented to make something like sandstone), (b) clastic dikes formed of sand and gravel that infiltrated down into cracks in the polar layered deposits, (c) clastic dikes formed from sand that was squeezed or injected upwards into the polar layered deposits from below, or (d) igneous dikes, composed of solidified magma (molten rock) injected into cracks in the polar layered deposits. In any case, the ridges were exposed to the air as wind scoured away the less-resistant polar layered materials.

I don't think that it looks like the "Inca city".
The "Inca city" features have a much more symmetric look than those from the ESA image.
"Inca City" is the informal name given by Mariner 9 scientists in 1972 to a set of intersecting, rectilinear ridges that are located among the layered materials of the south polar region of Mars. Their origin has never been understood; most investigators thought they might be sand dunes, either modern dunes or, more likely, dunes that were buried, hardened, then exhumed. Others considered them to be dikes formed by injection of molten rock (magma) or soft sediment into subsurface cracks that subsequently hardened and then were exposed at the surface by wind erosion.

Mikesingh, may I ask why you reffer to this lines as an inka city. What makes you sure that this is inka infrastructure?
