Pennsylvania Bluestone 

My Pa. Farm is full of blue stone….gorgeous stone to work with….i did a fireplace with it last year

I picked up at Meshoppen in mid 90's for a company I worked for in Wisconsin. Much smaller back then.

This is a great video holy cow. We have so much blue mudstone in our state! It's a' dime a' dozen. Let's hear it for the prehistoric shallow seas that deposited all that mud!!

Grew up with a blue stone patio my dad put in. PA boy 🌟

This is a very informative video. It shows different design that can be made out of the Bluestone and how it was made
