Structure on mars ?

[MandyFr87]

Hello, I was looking through photos about Mars and came across an image that intrigued me. I would like your opinion. I'll give you the image and the link to view the image below. The image is MOC1000782

https://viewer.mars.asu.edu/planetview/inst/moc/E1000462#T=3&P=E1000462,E1000782

There appears to be a structure in the center, in several stories with another rectangular area around it ?

Sorry if my English is not perfect.

Thank you to you

i see several similar "looks" in your pic

the description says its the "south Polar residual cap"

Article:

The portion of each martian polar cap that remains frosted through the summer is known as the Residual Polar Cap. It is also sometimes called the Permanent Polar Cap, although from one summer to the next the amount of frost that remains might vary.

article about a different pic but might help explain what you are seeing

Article:

when the surface was covered by seasonal carbon dioxide frost, so that surface relief is easily seen. Illumination is from the bottom left, highlighting long troughs at to the right and round pits and irregular mesas to the left of center.

These unique landforms are common in the south polar residual cap, which is known from previous Mars Global Surveyor images to be eroding rapidly in places. Right of center, polar layered deposits are exposed on a sun-facing scarp. These deposits are older than the residual ice cap, and the layers are thought to record climate variations on Mars similar to ice ages on Earth.

That is not a structure, standing several levels above the ground.
That is a hole in the ground.

Illumination is from the upper left.
The dark edges on the left are in shade, showing they are facing away from the source of illumination.
If this was a raised structure those edges would be white.
The black patch surrounded by white, on the right side of the depression, is where the brightness was so high it saturated the brightness settings being used (whiter than white). You can see other places where there are black patches surrounded by white, on the left sides of other ridges facing the source of illumination.

i wasnt sure what she meant by structure. i see an inground pool with steps leading into it on the shallow end.

Look at the following post to see examples of natural structures on Earth that have straight lines etc.: https://www.metabunk.org/threads/cl...an-ancient-square-structure.13980/post-335396

The resolution of this image is about a meter per pixel. Other portions of the same long strip look as if they're scalloped, rather like one finds when travertine terraces form around the edges of a mineral-rich body of water. I think your image is a natural feature.
