This isn’t a full blog post. Just something I saw while looking around for other things on Mars. And for once it’s (probably) not related to the wind. But it’s cool enough to share.
I saw something that went “squish” ???? .
This is a ~1.2 km (0.75 mi) wide crater in the northern mid-latitudes of Mars. I don’t know much about this region geologically (haven’t done my homework, as this is just a quick look). This crater has a set of layers in it that have partially eroded away. And underneath those layers on the crater floor are what look like the remnants of something that got ‘sploded from underneath those layers.
Judging from the direction of the ‘sploded rays, it came from under that beak-shaped part of the layers.
And I can sort of convince myself that maybe the squishing event happened once the layers got to the shape they’re in now – in other words, the squish happened after the layers had already formed and maybe even eroded some (rather than the layers being stuff that piled on top ages after the squish happened). Maybe the layers piled on something with ice in it, and the pressure eventually gave way.
Maybe. You could argue either way.
If anybody knows more about this thing, let me know!
