Here is an interesting object in the middle of Alluvial Fan.

PSP_001415_1875 was studied by U of Az for Alluvial Fan characteristic on Mars.

It was this same photo that was mailed to John Lear since they wanted us to look at the usual tracks on Mars. I posted this in full details in another thread.

Later we found this usual object on this same photo.

It does look like something unnatural.
Could it not also be a stone of a nature that when it breaks off it tends to do so at right angles?

AD.....the feature in the pic looks smilar to about 5 or 6 other features in the same pic.....but straight lines, right angles and sharper angles do occurr in nature.

A regional pic of the area would help to identify potential causes of such a feature

i can understand a rock breaking in straight line or right angles,but this rock appears to be on its own,you expect to find similar rocks nearby perhaps.Yet this one appears alone.Where in nature does rock make rectangles and rightangles?its just that i thought about my first sentence i typed and it occurred that I don't remember seeing any,not natural anyhow.

Rohnds, when you post these, it would be a good idea to post a link to the Nasa original each time. An image like this means very little without some opportunity to cheack some measure of authenticity.
Cheers

Why is there a nice little circular discoloration around the anomaly that is not found anywhere else in your picture?

Why is the anomaly more pixelated than the surrounding area?

macdaddy.....there are rectangles in nature.....along with straight lines, right angles and also shaper angles.

I'll find you some squares and rectangles soon as soon as I can find the beaches in tasmania where they exist....I'll be back in a few hours......and as I said in my previous post there were a number of similar features to the one in question.

I think seeing the regional views would come in handy...

macdaddy.....here are your squares and rectangles.....

Its called tessellated pavement and this pic is from Tasmania

I'll find you some squarish boulders next.

Whoa! Is that a natural formation? That's really cool. I image it's caused by layers of rock being eroded by the water?

K-rex....its a natural formation.....its called tessellated pavement.....I believe the University of Tasmania has a good write up on it.....or look it up on wiki.....

Rohn it would be nice if you answered questions posed to you in other threads instead of ignoring them and starting another, in another thread you stated what i am about to quote below...



You accuse NASA of usually deleting objects from photos, so i asked the question i'm about to post below...



So PLEASE answer my question, if as you say NASA normally delete objects from photos, where do your photos come from, if they are direct from NASA, well then for you to say that NASA normally deletes objects is very flawed, or you wouldn't have any photos to post in the first place...

I await your reply.....

Thanks castle bravo,great pictures,never seen anything like it before!

macdaddy....not a problem.....geologic processes are a wondrous thing.....I've large blocks as well in person....I just have to find pics of them.....when I find them I'll post them....

Fen.....its likely he agrees with the analysis he was given and then moves on without bothering to answer......

It appears so my friend, no doubt he'll wait for this thread to die down and then he'll be back with more piccys....

Fen.....I do find Martian geology quite interesting.....he does find very good examples.....I/we just see different things......

Sorry it took so long to get back to you. I'm not contesting that it's a natural formation: it just surprises me. It's actually pretty easy to see how it's formed: layers of sediment being washed away, the action of the waves breaking layers into little 'bricks'. It's cool though. I actually vaguely remember seeing this in a magazine somewhere.

The mountains that get misidentified as step pyramids have the same processes sometimes. Mind you: some mountains really ARE pyramids.

When I first saw your pic, I was going to joke around and say something like: "Oh, my gosh! It's pavement from an ancient civilization!" But I was afraid some people might take it and let their imaginations run loose.

rohn....is this why you never answer back?.....

fen.....he answers selective posts and ignores the rest.....unless he wants us doing his research for him.....

Hey rohnds.. long time. Forget that rock.. look below at the shadow of the circular rock. Is it natural or is it a rendering thing being so far away from the camera? That object below it near the bottom looks like a perfect circle.
