NASA image: Sedimentary signs of a Martian lakebed

This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA's Curiosity Mars Rover shows a pattern typical of a lake-floor sedimentary deposit not far from where flowing water entered a lake.

The scene combines multiple frames taken with Mastcam's right-eye camera on Aug. 7, 2014, during the 712th Martian day, or sol, of Curiosity's work on Mars. It shows an outcrop at the edge of "Hidden Valley," seen from the valley floor. This view spans about 5 feet (1.5 meters) across in the foreground. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Figure A is a version with a superimposed scale bar of 50 centimeters (about 20 inches).

This is an example of a thick-laminated, evenly-stratified rock type that forms stratigraphically beneath cross-bedded sandstones regarded as ancient river deposits. These rocks are interpreted to record sedimentation in a lake, as part of or in front of a delta, where plumes of settled out of the water column and onto the lake floor.

I was curious as to what young earth creationists had to say about sedimentary rocks in Mars. After all they believe these were formed on earth during that flood god dumped in order to flush the earth of unrepentant sinners. But why Mars, an apparently sinless planet?

Of course they have answers. In genesis.

"Where did the water on Mars come from? Probably both from space and from the interior of Mars. Many creation scientists have suspected that the Genesis flood was a catastrophe which affected the whole solar system, not just the Earth. If high-velocity chunks of ice made the craters on Mars, the ice would turn to water vapor upon impact"

-Apparently god found it necessary to scour all the planets as well as moons and many asteroids. Note the outrageous ad hoc science speculation throughout. For instance, no need to actually look for evidence of whether craters were made by ice impacts - assuming that they were is more than adequate for creationist theoreticians.

Creationist 'scientists' spend minutes concocting theories which take hours for real scientists to unravel. Meanwhile, hapless believers read only what they see on creationist websites, never getting to see what real science has to say.

And worse, the creation scientists ignore the rebuttal and continue to reprint only their concoctions, along with an abundance of circular references, giving the impression that real science is struck dumb by their revelations.

To inject some actual science, I was wondering how these deep layers of lake sediment were exposed and fragmented. A chance hit on the lake by a meteorite much later when the lake was dry?

Or post deposition water erosion of the softer layers undercutting a harder cap layer (portions of which are seen collapsed in the photograph).

You might want to try some actual research instead of whining 'feed me'.

"After the crater filled to a height of at least a few hundred yards and the sediments hardened into rock, the accumulated layers of sediment were sculpted over time into a mountainous shape by wind erosion that carved away the material between the crater perimeter and what is now the edge of the mountain."

Ditto. Why guess? This is the internet.

Hi Otto,
Your attacks on the Creationists do no not threaten my God.
Science versus religion is a cration of Lucifer, a destructive meme virus.
My God is well supportd by the quantum erasure experiment, which is poison materialism as it shows that there is nothing "out there".
The evidence supports the idea that You are creating your reality from a sea of probabilities as you observe.
So You too are a Creationist.
But perhaps you do not want to go that deep.

His point may have been: what caused the sheer surface seen in the photograph? The page you cited doesn't address that; it speaks only of the larger mountain structure.

For his temerity in criticizing your earlier posts, I note you've ranked both RCole's comments. Some might see that as petty. Few here enjoy enduring creationist spam, and your points in those posts are well made, but there's little to be gained by such preemptive diatribe. Instead, just report religious doctrine spam to the admins. It works.

Hi Otto,

Apparently neither do evidence or logic. The definition of faith is the disregard of these things.

No, god is a destructive meme virus. Did you not read Dawkins book?
My God is well supportd by the quantum erasure experiment, which is poison materialism as it shows that there is nothing "out there"
Your god, whatever you've made it to be, is not supported by anything besides your imagination.
The evidence supports the idea that You are creating your reality from a sea of probabilities as you observe.
So You too are a Creationist.

No deeper than reality. Poetry is not reality but it's certainly easier just to sit there and make it up.

The page I cited has pictures with links at the bottom which do address that. Did you look any further? Why do you or cole need someone to do this for you?
Some might see this as petty.
Some might see people who refuse to do their own research as lazy. These people will always get a 1/5 from me, whether they presume to tell me what I should be posting or not.
just report religious spam
Science and society are in extreme danger from religion. It is VALUABLE and WORTHWILE to see their arguments and to counter them in the public venue.

The only way to defeat religionists is to confront them. They will continue to post and I will continue to expose their lies and explain the threats they pose.

Is that ok with you?

Otto: You are doing a worthwhile thing. Be the terrier snapping at the heels of trolls and religionists. They should not get free reign on a science site. And others, by all means report. Whatever encourages them to go away, do it.

Fain---Too bad you just feel to get rid of people that you don't agree with. Pathetic. I wish you would rather engage in decent dialogue.

Ghost---I would answer you if I could expect to have an adult discussion, but based on past experience, that is not an option with you.

Have you ever read the verse Matt 7:6?


@verkle reminds of the old adage. "Ninety-seven percent of men admit to masterbating, the other three percent are liars" Verkle's part of the three percent.

@verkle
it has nothing to do with agreeing/disagreeing with anyone... this is SCIENCE, not a conversation about cultural differences and why they should be accepted or rejected... and religion always takes a restrictive view of reality refusing to accept SCIENCE, as proven by your own posts and other idiots, like ren82 and jvk
Have you ever read the verse
and so you give a demonstration of your inability to come to grips with SCIENCE

have you ever learned about the laws of physics?
WHY discuss something that is SUBJECTIVE to the individual like religion, based upon a fallacious source, when you can discuss SCIENCE, which is supported by empirical evidence?

the laws of physics describe and dominate your life, and yet you refuse to acknowledge them and their powerful methods of prediction... which is a FAR better method than your subjective book, stolen from other countries
