Cropmarks at a protohistoric site at Grézac, France
Cropmarks or crop marks are a means through which sub-surface archaeological, natural and recent features may be visible from the air or a vantage point on higher ground or a temporary platform. Such marks, along with parch marks,[1] soil marks and frost marks, can reveal buried archaeological sites that are not visible from the ground.
