In the Cliff to the north of the main Car Park at Trebarwith Strand is an area of overhanging coarse rock
above a layer of fine grained rock , both from the Lower Carboniferous Period.
The rough rock was formed during a period of explosive undersea activity when blobs (bombs)
of volcanic molten lava / ash were blasted into the air.
Volcanic bombs undergo varying degrees of aerodynamic and /or impact shaping, depending on their fluidity,
during the flight through the atmosphere and subsequent impact.
