That’s quite the mud hole… trip and fall in that one head first if you can’t roll around you might just drown in it…
Saw something about a mud pit in California that moves further on its own every year…scientist are puzzled what is powering its movement but it is moving 20 feet a year and a railroad built a wall that was 100 ft long and 5 stories deep (75 feet)and the pit managed to break around the bottom of that wall and keep going…
It was threatening a Union Pacific railway section of track along with fiber optic cable, petroleum pipeline, a section of roadway, etc.
Smithsonian did an article about it back in 2018.
https://www.smithsonianmag.com/smart-news/gurgling-mud-pot-crawling-across-southern-california-180970787/Wikipedia reported that in 2020 it accelerated its movement to 10 feet a month!
It is possibly driven by a fissure or fault off the San Andreas plate which is nearby or possibly by tunnels from CO2 mining in the early 1900s. It is releasing carbon dioxide gas…and hydrogen sulfide gas so it is pretty stinky too, as well as having water forming a deep quicksand like mud pit aerated by the C02 and Hydrogen Sulfide gas. It is near Niland in Southern California and it is a few miles from the Salton Sea.
