A "Doorway" on Mars? Curiosity Rover Mastcam Image Sol 3466

[gordi]

Greetings fellow Rogues,

I've just stumbled across a rather.... "interesting" image, in the MARS Exploration (raw images) section of the official NASA dot gov website. (*I know... I KNOW!!)

It reminded me of the guy on ATS that we all used to laugh at, for seeing shapes in Moon/Mars "rocks" which inevitably spawned the hundred question debates....

Is there life on Mars?

Was there ever life on Mars?

Do you ever see out of place "things" in Mars images?

Aren't they "just rocks"?

Did we even send probes to Mars?

Are WE humans on Mars?

So, just for the jollies.... 
What does this look like to you, in Mars Curiosity Rover's Mastcam image Sol3466 from 7th Jun'22?




LINK to original raw image

I wonder what size that thing is??

Cheers,
