This rock was found deep in the woods in Plymouth, Massachusetts. My parents looked all around to see if there were any more like it, but the only one with a similar conglomerate look was grayish so they left it. Because one surface is so flat and it’s so green, my immediate reaction was it was some kind of manufactured stone countertop material, but again, it was found deep in the woods...and the other surfaces are rough. What thinketh you? Thanks for any ID help.

Not unusual to have a naturally carved flat surface, especially when glaciation has occurred. I'm no expert, but it looks like a piece of epidotized conglomerate....Others here will have a better ID.

Plymouth County is known for "Puddingstone" conglomerates, some of which (e.g., Roxbury Puddingstone, the Massachusetts official State Rock) have been used for decorative building stones and monuments. It comes in various colors, including greenish. Your piece is attractive. I've seen some nice Puddingstone gems, and hopefully yours will hold up to sanding and polishing.

I grew up back there and somebody has lived everywhere back there at one time or another. I agree with natural puddingstone , I used to rock climb on it near Boston and it outcrops in spots all the way down to central New Jersey. At times it can be very tough and with the right mix of rock in it quite beautiful. The east coast has lots of lapidary rough but you need the skills of a safe cracker to get it and not get caught. My best score ever was gorgeous chatoyant sunstone from New Jersey.
