Foreground stone is around 11ft long, second stone (standing) is just short of 6ft. Beyond the second stone is a low stump about half a foot high and very thin, the slab lying in the foreground could perhaps be the remainder of this stump or another fallen stone. There is also a stump standing perpendicular to the row just at the tip of the now fallen long stone.
