Mysterious White Rock Fingers on Mars

Explanation: What caused this unusual white rock formation on Mars? Intrigued by the possibility that they could be salt deposits left over as an ancient lakebed dried-up, detailed studies of these fingers now indicate that this is not correct. The light material appears to have eroded away from the surrounding area, indicating a very low-density composition, possibly consistent with volcanic ash or windblown dust. The stark contrast between the rocks and the surrounding sand is compounded by the sand's unusual darkness. This picture was taken from the Mars Express spacecraft currently orbiting Mars. Planetary scientist Emily Lakdawalla, among others, has followed her curiosity about this unusual Martian landform into a fascinating investigation that is eloquently described in the Planetary Society Weblog. The mysterious white rock spans about 15 kilometers across inside a larger crater that spans about 100 kilometers.




I'm in denial and still think it's salt, but but then it would be a precipitate from a water solution. So halobateria?

Hmm, maybe some sort of chalk, perhaps when Mars was warm and wet millions of years ago, very primitive life had time to form, though I think that may be a long shot. I'm very familiar with Mars, what region was this taken in?

No doubt many on here will see it as an alien face built by some advanced Martians!!!

It's just that alien kid messing around again. Probably making dust angels.



Damn space tourists.
