PRAWR = Prehistoric Rock Art of the West Riding (Boughey & Vickerman) |
These two naturally shaped rocks
stand on the western edge of Rombalds Moor above Silsden. Their strange shape
is due to the fact that the top part of the rock stack is a hard gritstone whilst
the lower part is an easily eroded sandstone. The top surface of both rocks have
cups,
the eastern one has 2 cups while the western stone has several cups along with
grooves and deep basins. |
