Pointed rocks

I just wanted to throw in the statement that there are an amazing amount of pointed rocks on mars. With the thin air and lack of water there seems to be little if any erosion taking place. Sharp angles and edges seem to remain after eons of time. Hollywood would have a hard time making a film set like this. Oh and by the way alot of them seem to look like pyrimids for whatever reason

I would think pyramids, the triangular-base type -- tetrahedrons -- would be high on the list of expected shapes of ejecta. The minimum number of planar cracks that are needed to create a rock from inside a thick slab of bedrock is 4. Four such random cracks create a volume that is a tetrahedron. Fling such a rock and it will almost always land on one of its faces, leaving a corner pointing upward.

I suppose it could even be that the cracks don't have random orientation and are influenced by a bedrock's underlaying crystalline structure. If you smash up halite, you probably get large cubic versions of your table salt. Perhaps there was tetrahedral crystalization that favored the production of rather regular terahedral fragments.

I haven't cracked enough rocks apart to know. Geologists?

I beleive that there are many things that have not yet been disclosed to public eyes.
I want so bad to turn the news on one day and hear,"We have found proof of an achient civilization".This would be as wonderous as them finding out that Edger Cayce was right about everything he said about Atlantis.

Blowing grit is a significant adversary over time, even for "fancy basalt."

If these rock shapes have withstood the elements better. and there are both rocks and fossils here being reworked over time. Then this could explain a few more things.

What is not explained, at all in my humble opinion, are the tiny structures which seem to be holding up so nicely. Tiny structues that just have such weathering abilities.

The prince of the air is a metaphysical being. It was Egypt which inspired mankind to fly like Horus.

You start by building pyrimids to transport the dead, you end by building the dead to transport the pyrimids.

Behold in wonder the resolute perfection of the fruits of the Spirit, as revealed through men.

Yes, Hud, most rocks/minerals do fracture along lines dictated by underlying molecular structure.

I noticed the shape of the rocks and wondered about it but I didn't like to ask.
So is the upshot that this is the expected shape but on earth they would have been eroded ?

All the shapes in the rocks you see on Mars are seen on Earth, particularly in deserts. For the 3 sided pyramidal stones try searching for drei kanter in a geological dictionary. Here's a couple of references

I apologize for hyjacking ye huge mystery.

Here's why I am perplexed, if this layer of gound is being reworked, what's moving material upward, besides the impacts? lol

Sorry, but it's just a little odd, all of it. I have to laugh a lot about what I'm seeing baby.

Thankyou Ian for the links I will go and have an explore having just finished work

This might interest some of you:

Ian's link is worth a look for any beginners like me it shows quite a few things here on earth that I can see happening on Mars it must be nice to be able to reconise features with a practiced eye I must be a closet geek

YES

They're ONLY, LONELESSY, ROCKS!

Rich,

Isn't it a little ironic, is all I mean, for those who truly understood the meaning of what I said. The shear irony is hilarious and a bit perplexing.

A dead planet like Mars is a good example for us, especially if there are fossils. A planetoid can go the opposite way of "grace."

Perhaps things went a little bad on Mars. lol Maybe a lot bad from the looks of some of the species in their magnificent battle attire.

Bizarre is the only word to describe Mars. Geologist or helpless paleo person, there does not have to be a schism. NASA is in the hot seat in more than one way, apparently. I'm waiting for some one to leak, anyday.

There must be a national security issue going on, maybe? Not to be paranoid, but the best stuff is not being published for the general publics viewing, or something is up.

The American people could be easily frightened by an outside force or power, unknown to man. We have no idea what has been triggered. We are not a completely open society, and I think that's a little sad. We're only getting the baby version.

Baby version or not I'm still impressed. You and I both know there are things in the released photos that are compelling evidence for past if not present life on Mars. the problem that I see is that even with all of the internet "eyes" out there that there is either intentional blindness or a general laziness to those who look but can not see.
I have viewed every single photo of the terrain with every advantage technology can give me so that I can know. I do not believe many others can say this.
So much energy has been spent arguing about the "possibility" of life and if at least an equal amount was spent looking, the census would be very different than what we see in this blog. What a waste!
I have made a book (not to be published) of my collection of photos and every single person I have shown it to first, doesn't believe they are from mars and second is absolutely floored.
I could go on but Very few who read this will respect what I am saying anyway.

Many argue, few actualy look into the images. I've noticed this from day one. You can argue all you want if life can or can't exist, here or there. Try combining your mental skills with some observation, and then talk about your theories of life.
