This week's benchmark is a unique one - not your usual NGS fare! It comes to you courtesy of Howard Allen, who says:
This is a quarry marker that the Royal Tyrrell Museum cements in place at their dinosaur fossil excavations around the Province of Alberta. This particular one marks a quarry at the Devil's Coulee dinosaur egg site in southern Alberta, near the town of Warner. The quarry marker allows the locality to be precisely marked by GPS (and/or conventional survey equipment), so it can be found again in the future.
