Hollow hills to the west of the former ocean in Elysium

[gregorme]

The interior of these hills is much clearer, the straight edges are unlikely to happen by erosion. B is an intact hill with signs of the roof collapsing, the hypothesis is the pits are collapsed versions of this hill. C and D perhaps have an interior support for a roof like the slice of bread formation. E has walls dividing it into 3 rooms.

This area that Greg is looking at is located in Phlegra Montes, which is located in the northern lowlands of Mars. The area includes a mountain range that separates the large plains of Utopia Planitia on the west and Amazonis Planitia towards the east. Phlegra Montes extends northwards from Elysium and lies due east of Hecates Tholus. Keep in mind that Phlegra Montes also directly aligns with the ruins identified in the Acheron region, along with those found in Cydonia and Utopia, across the northern hemisphere of Mars.

Here is a context image (Figure 1) showing Greg's collection of pitted foundations (labeled I) and an isolated foundation (labeled II) that sits among a large group of craters.

Here is a close-up of the pitted foundation (Figure 2) that I have labeled II in Figure 1 - in the above post.

Segmented Mask

Notice the angled rooms and walls of the foundation takes on the form of a segmented mask.

Here is a crop of the hollow foundation labeled A in figure 1.


Figure 3
Fish Head

Notice the collapsed "pitted" center and thick linear walls along the southern and western sides and the mound of debris on the lower eastern side.

Here is a crop of the hollow formation that is labeled C in figure 1.


Figure 4

Notice the overall square-shape of the collapsed center and the smaller polygonal foundations attached along the north eastern side.

Here is a crop of the hollow foundation labeled D in figure 1.


Figure 5

Notice the rectangular shape of the foundation with its collapsed center and the triangular foundations on the northern side. There is also a flat, rectangular mound attached to the eastern side.

Here is a crop of the hollow foundation labeled E in figure 1.


Figure 6

Notice the linear walls of the hollow foundation form three compartmentalized rooms that have a rectangular and triangular shape, while the eastern wall is curved. There is also a large circular mound, topped with debris, sitting on its western side.

Often you can see an entrance in these images, but these would not be visible from above or they are blocked. On the bottom of this formation there is a door to the outside. There are then corridors into the two rooms.

There may be 4 doors here but the resolution is not clear enough to tell. The 3 rooms might have been separate dwellings, A seems to be collapsing and would be a good hill to investigate even colonize. Creatures living in these might have used perishable walls like wood to separate it into rooms. Other images have shown walled rooms so it appears they would have found rooms useful. So it's likely some of these hills would have signs of ancient furniture and walls. I don't know if anything could survive, but with a cold and dry atmosphere there may have been no rot as there would not have been bacteria to rot them. If some hills collapsed then the debris might have solidified in the shape of furniture and walls, or like petrified wood. Even like Mount Pompeii where the outlines of people were found, in some cases this may have happened on Mars too.

Here is another ruined formation with geometric and polygonal walls found in the Phlegra Montes region of Mars. I've titled this formation Mushroom Skull. It is located near the first set of formations that Greg found, in figure 1.


Figure 7
Mushroom Skull

Notice the three main rooms appear as a skull-shape with an attached dormer on the north-western side. This walled formation is very similar to the foundation observed in figure 6.

I discussed this formation in my book, labeled A in the image. The interior support wall is similar to the slice of bread formation, a common way in engineering to reduce the stress on a roof. There is also a small entrance to the attached room, this is important because a habitat would need some way to get from one room to another. A natural formation would not need these entrances, or materials like ice building them up would tend to leak out of holes like this compromising the structure.

This may also have been used in the flipped roof formation, the roof folded half way across it and perhaps came up against this interior support.
