Perseverance Ruins

[starjim]

Joe White really opened my eyes with his find of the wall above. He also pointed out a joint in what I thought was a single carved rock. The fact there was a joint meant that the stones had been worked. Since then I see things differently and the next images show there are joints in several groupings of stones that are carved and fitted.

This is the link for the ArtAlien TV video of the wall and jointed stones. He also has a Gigapan of the site which clearly shows it is a ruins.

There is a new set of images from Sol 201 or so forward that is called the Citadelle by NASA. It is truly a ruined fort of multiple levels. There are several including ArtAlien TV that show overhead context images for this location and how it fits in with miles of walls and or canals where the rover is currently walking along. I decided to focus on some of the stranger objects skipping past the stacked blocks of construction which we have become familiar with at this crater.



This is a solid block lying flat on the ground, it is unknown how think it might be. At a right angle and along its edge is a second block about 3" thick. It is fixed to the one below and forms a right angle. I have to ask the question, most of the blocks around this have been toppled by the consistently strong winds and other erosional forces. What is keeping these two blocks together?

[starjim]

Next up is a grouping of blocks that I found curious in an area that NASA calls the Citadel. There are two objects that I'll bring to your attention to:




The Citadel area - context (Sol 204)




1. is a block serrated along the edge. I haven't seen anything quite like this before.



2. is a large boulder that has two shims in an obvious gap in the stone.

The third and fourth offerings include the following; a flat geometrically shaped stone and a falcon or some other bird of prey. While I think that the bird is Pariedoilia it is striking in itself and worthy of a mention.




3. is a flat stone that is interesting for the geometry. Notice the two right angles cut into it on either side.




4.a falcon or some other bird of prey

Today's offering is that of the top of a stela which shows two carvings. I have circled them and offer that on the left is a eroded face in relief, the right side having been mostly destroyed. Right next to the face on the right is a pretty good carving of a frog, looking down at it from above. Reminds me of Gobeckli Tepi carvings in relief. As I was finishing this up I did notice another small face which is circled but not really worked up. More think that is again Pareidolia.

This is a Jpeg of the Citadel Gigapan done by Neal Spence. Some of my postings are within this overall view, some are to either side of where Neal cut off the gigapan. But this should give you an overall idea of the location and how it is terraced and in ruins. Any Archaeologist would grab a shovel if confronted with this site.

Another stone in the same sequence as the tri-stones shown earlier. This has a small hashtag on the lower left and an inscribed rectangular feature in the center with lines inscribed from top to bottom... A natural occurrence I'm sure 😉

[starjim]

A pair of stones I call Tri-stones. they lie out in the open but near each other. One is smooth and finished the other is rough, but they are both the same shape. curious.

Here is another image from the general area of the Citadel. I commend others that are pointing out the construction typical of this area, showing lots of stacked stone slabs and odd shaped stones. Below are three stones obviously stacked. The thing is the middle stone is curved and the top stone is nestled perfectly into the curve. Amazing.

[starjim]

This area has been imaged quite a lot from basically the same angle. What I wanted to point to is the huge blocks at the top center of the debris field. My arrow points to a vertical split between two stacks of flat material.
I actually spent a bit of time looking online at different strata and how it accumulates over time. Layer upon layer it stacks up. Some layers are thinner and others thicker. That's basic geology. What doesn't happen is for layers to accumulate at different rates over numerous layers on either side of a vertical split. The vertical split will normally be angled or erratic or cross over from one layer to the next.
So the point here is this is odd and informs us that this is not a natural occurrence.

This one is obvious even to those that only see rocks. When does Mother Nature stack rocks to a height of about 4' in a square pattern? I think the square is about 8' to 10' across.

My last post was about a square structure. It is also pointed out in this post. As I advanced through the image gallery I noted that there was another square structure, more ruined, above the one I pointed out. IT has been observed by other researchers (check out ArtAlien TV for one source) that this area is part of a long complex of walls and structures running the length of this area now under observation by the rover. It is obvious that this is so when you look at the overhead images provided by HiRise and other cameras.
I note that there are many instances of long runs of debris and broken rocks, then we run into piles of rocks. This has been a common theme in Jezera crater.
Think about the typical protective wall system. Whether it is for channeling water or for protection against invaders. There are always towers or buildings that anchor the wall. This shows two such structures, which I have pointed out.
BTW the left lower box doesn't look like part of the square, that is because the standing rock is so tall, it blocks the point at the ground where I would've placed the red box.

This image and the others in this sequence are really filled with lots of interesting objects. I picked out the one that really jumped at me and deserves its own posting. There are also a lot of foundations in this grouping of images. which I will look at in subsequent postings.
For now enjoy the Ewer handle. I see a bit of a carved head to the right but think its just pareidolia.
Now I have to caution myself that the rounded feature might be a trick of the eye incorporating two rocks to make one feature? But I'm pretty sure this one is as presented.

[starjim]

I've been sitting on this one for a few days now. There is so much in this image that I just got lost in it. I finally decided to highlight the most obvious (to me) objects. Also lets remember that this is along a line the rover is traveling. It is clear that we are looking at a lengthy construction, most likely a wall running for miles, with buildings and towers built into its length.
So here is what I see in this image by the numbers:

On the left side of the ridge is an "L" shaped length of wall. It rises about 2' to 3' above its surroundings.

2. Next moving to the right we have a more complex structure, it is the shape of a "T". It also has more structure behind it which I couldn't make out too well.
3. This breaks one of my own rules about trying to see too far. But I thought it was obvious that whatever this is, it was not natural. I can make out three chambers and one large square block (on the right of the object). It looks like a domed building that has had part of the dome blown off, revealing the three inner chambers. But again it is pretty far away.
4. This is yet another "L" shaped wall about 3' high
5. A strangely shaped rock, that has a very nice half hole cut into one edge.
6. The foreground has a large foundation in plain view. I drew lines to indicate the outlines of this structure. This along with an earlier structure I showed are the best examples I've seen up close of actual ruins on Mars. For comparison I repost the square ruined building I posted a couple days ago from the same area.
Can anyone show me a natural feature here on Earth that is rectangular and rises a couple feet above the ground, using stacked stones, fitted together??? Nah This is just a bunch of rocks!!!!!
