On Twitter someone said that it looks like the result of lightning striking sand. I did not know that this would create such awesome structures. Look up "lightning sand" if you never heard about it.
I think those are called Fulgurites:

- ivan_gammel 5y agoLightnings seem to be rare on Mars. If this one was caused by it, what are the chances it would have been discovered? https://www.space.com/mars-lightning-weak-thin-atmosphere.html https://www.space.com/mars-lightning-weak-thin-atmosphere.ht...
- chmod775 5y agoConsidering it's a mostly barren landscape with little that could wear down and prevent accumulation of such things, chances are pretty good. Mars isn't quite the Moon, where you could drop a marble and expect to find it in exactly the same condition 10,000 years later, but it's not quite Earth either. There's no organisms that will cover and break down anything you throw at them within weeks, obviously there's no rain that could cause erosion, wind speeds are about the same you'd see on earth, but atmospheric pressure is only about 1/150th.

- peterburkimsher 5y agoLet's analyse the chemical composition. If it's is made of fused quartz, it's likely to be a fulgurite. If it's made of calcium carbonate, it's likely to be a coral. If it's made of something else, that's even more exciting!
