Forest on Mars !?!?

God job Tex - didn't see that one...these long tracks seems to be everywhere. This lower has identical path with upper one.

* nice and clear tracks, that's for sure...

For this one down - we know - it' rover tracks

In the image of the alluvial plain, it was pointed out that there were tracks. Sure enough, there is a y shaped pattern.

But, just below the one discussed is a second, fainter set of identical tracks. It doesn't really look to me like it was photoshopped in or anything. Not sure what it is.

I counted 8 tracks on that area, all looking like they were made by rocks that are at the end of the tracks.

I will try to find the link to the original photo.

Ask yourself: what condition is NECESSARY for cyclone ( and this one ain't small) to form.

A lower atmospheric pressure at one point that starts a vertical air current that rotates because of Coriolis effect, I think.

Usual answer is “boulder tracks“.

Here is also one long track :

nasa


* same as famous Moon tracks ( pointed by Zorgon)

If we don't know - that this are tracks from Spirit - what would we “see“ and comment: “boulder tracks and a small rock“ (in fact being Spirit

I don't know what I would say if I saw that photo for the first time without the explanation, but it looks different from the other tracks.

It's a continuous line and as many curves, it does not look like a track made by something tumbling down a slope like the others do.

For example - these one are pretty straight ( they would look straight from satellite view also).

Maybe, they are not completely straight, so I don't know it those small changes in direction would be noticeable or not.

But even if they look straight from far above they look like they have other characteristics that are not present in the other track photos and that could make it look like a different type of track:
the area looks horizontal, not a slope
the tracks are continuous, not broken

Who can tell me what these two images are about - I'll tell later...just interested in interpretation

First - do you see in Tex image, the upper one- parabola curve- that the rock( looks to me..I'll tray to found strip image) is going UP the hill!?

Second - I asked you before - rover image looks just like image of these rocks!?

There are more tracks on that image. At the upper right corner, i found these. They seem faint but make a near perfect circular arc:

Sinkhole...

"A sinkhole, also known as a sink, shake hole, swallow hole, swallet, doline or cenote, is a natural depression or hole in the surface topography caused by the removal of soil or bedrock, often both, by water. Sinkholes may vary in size from less than a meter to several hundred meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. They may be formed gradually or suddenly, and are found worldwide." - wikipedia

You might have meant subduction, but that requires plate tectonics

I see the track clearly....and I see also a lot of rocks of different size - and ONE track in this part.




But one (upper in the middle ) rock - has a pretty nice shadow

...but if you look closer they ARE broken...

Here is an image from Sol 42. The rock formation is called "Flat Top". It looks very similar to an altar.

...very broken indeed

Why do you call them "massive" and "heavy"?
Aren't those clouds just little more than fog over that area?

Those black shadows they leave tell me they are thick and heavy. have been in many heavy fogs... I have never seen a shadow

Tex, do you know the region?
..... very sharp angles

- what a “thin“ atmosphere
