This is one of the old FR postings that started my search.
I was looking for an update on the Cargill mine collapse on Avery Island. A FR search brought up lots of articles from the past, but the Cleveland salt mine was not posted yet.
I didn’t see much of an update on the Wieliczka salt mine from the last time, so I started with this mine.
Trying to find non-political postings, and things of interest to new FReepers young and old.
Impressive!
One of the most awesome places I've ever been to.
