[Rockhounds] Ohio Celestine cave

[Stephen Shimatzki]

Linda, I recall a story a few years back of some place in northern
Michigan.  (Pre covid, but I can't recall the year or town)  basically it
went like this: There was a large thundering sound one evening and a farmer
thought it was odd but dismissed it as a plane.  The next morning when he
went out to check a fence and there was a huge fault line opened up in his
field.  At first it was assumed an earthquake and unknown fault but later
it was determined to be the result of bounce back from the ice age.  The
rock under stress for so long, finally just cracked.  Much like me at work
during harvest season.

I think I tried looking into it a few times but couldn't find anymore
info.  I didn't know that led to folks thinking the lakes are shrinking,
but that doesn't surprise me.

Steve
