It looks like something from a cave.
It has the same look as stalagtites or stalagmites.
Go google a picture of a stalagtite or stalagmite, or cave formations,
and you will see something that looks JUST LIKE THAT!
I found it digging about 3 feet down in the swamps of louisiana...along the texas border where the ocean used to run all the way to canada some millions of yrs ago.I got some more strange things from the same area if you would like to see them.
Cool. I have seen similar formations from lightning strikes hitting sand. The super high temps actually fuse the sand into glass. The resulting formations resemble a small bolt of lightning.
Just a guess though, sweet find!
luckysgirl, is tht a giant doobie that Lucky has in his/her mouth? I've been trying to figure that out all evening! Oh, the rock formation....stalagtite I think? Monty
