Identifying Polished Rocks?

Question

I found a bag of polished rocks I picked up in a state park gift shop but can't find the postcard that identifies them. The card only listed what rocks they had so it was easy to tell what was what. Does anyone know where I can find another card? Or something that shows what that selection is?

Answer 1

Most state park gift shops sell the cards separately or come complementary to the rocks.  I was at Bushkill falls a couple days ago and bought a few rocks for my little cousin with the cards so he can learn little by little the names of the rocks and how they are made.  There was one card I was not able to get because they were waiting for the shipment of new supplies.
