> Yes I did open the last barrier by knocking down the pillar and used S, NE, W, SE, N, W, S, SW from white sandstone to black sandstone and then back up frm black to whtie and followed the hints page saying stay in white sandstone and will find Verna's pc and key but nothing.

The pillar doesn't have anything to do with the barriers. Find the place where it says "You are at the third barrier across the central railway. The access door in the middle is shut." That's the one I'm talking about. You need to get that one open before you can solve the main sandstone puzzle, because otherwise the mine cart is blocked from going where you need it to go.
