Description: Castle Rock, Stirling. Looking south-east from Raploch. Stirlingshire. Crags of columnar quartz-dolerite of the Stirling sill dipping eastwards. The 'wind-gap', or pass, of Ballengeich is seen slightly to left of centre. The Stirling sill is known from borehole evidence to be about 300 ft. thick and is intruded into various horizons ranging from the top of the Calciferous Sandstone Measures to about the middle of the Limestone Coal Group (both Carboniferous). The wooded scree at the foot of the escarpment conceals an outcrop of these underlying Carboniferous sediments. The outcrop is exposed behind the houses on the left. The outcrop here is one of several striking westward-facing crags which extend south from Abbey Craig and Stirling Castle along the western limb of the Clackmannan Syncline, a major structural feature of the area.
