There's one much smaller than that on the north west shore of Llynau Cregennan, it's about 3 ft high and 2 ft wide. But how could the smallest standing stone ever be identified, I et the feeling that in a nationwide culture placing stones, wouldn't there be the most tiny stone placed somewhere by someone? There may be millions of tiny standing stones that are only placed 6 inches into the ground? Or does soil erosion preclude this?
