I found this rock at a second hand store.
Can anyone tell me what I am looking at?


Thank you,

Maybe a mineral deposite, limestone?
Like a stalagmite.
There is a rocks and minerals section here you might want to post there also.

I was thinking that it was some kind of a cave formation. Thank you
