Interesting article.

Thought it was a failed oil exploration well causing a dissolution cavern.

Turns out to be a salt cavern after all. Hard part is working out how the salt cavern was formed as it is in a swamp zone so as a result it is likely to fill with water before even getting to the salt dome. Could have been a dissolution cavern in the salt dome with the brine recrystallised for salt later. End result in that case will be the same.

Gas charged water surges likely due to pressurisation of the water/gas mix due to a collapse of the roof. When contents of cavern finally squirt out the roof goes down @ the same rate.

If a dissolution well, then the current swamp conditions will guarantee the dissolution & collapse of the entire salt dome until the goop collapsing onto the crater seals the dome. Should create a very impressive slightly salty lake.

Have a nice day: Ag
