Rock growths on Mars!
Click for full image.
Cool image time! The photo to the right was taken by the high resolution camera on the Mars rover Curiosity on May 15, 2022, and shows several incredibly strange vertical fingers of rock that appear to grow out of the ground. From the caption:
These likely formed as groundwater trickled through rock in the ancient past, depositing mineral cements over time; many years later, when the rock was exposed to the atmosphere, wind eroded the softer material around the cemented portions.
This formation explanation of course is only an educated guess. There are other possibilities, suggested by how cave formations grow over time, that are less likely but still must be considered. For example, maybe we are looking at a feature that grew upward as condensation from Mars’ once thicker and wetter atmosphere deposited new material on it over time.
Unfortunately, the image release does not provide a scale. My guess is that the longest finger is between six to twelve inches long, but it could be much smaller.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

And they must be fragile as heck — look at how thin the base is.
Its ALIVE!!!
Looks a little like ground stuck lightning also. But that is not possible in the last few million years.
Thanks for highlighting this, Bob.

UMSF member “fredk” posted this anaglyph along with a cross-eyed version. I can’t do the cross-eyed easily, but I still have my “Mars 3-D” glasses used during Spirit and Opportunity. (Has it really been 18 years…?)
From my perspective, the anaglyph shows the larger cobra-like finger to be much flatter and wider than first thought. I can see how these fingers were thicker layers of the parent rock that broke off, tilted down and then the resulting weathering left them sticking up. There are several more sheet like sections below and right of the fingers. Just my two cents.
That 3D shot of them, noted above, is pretty amazing.
