Southern Sandstone

[1] The horizon of thick, cross-bedded, fine-to-medium grained quartz sandstone separating the Tunbridge Wells Sands from the overlying Grinstead Clay is known as Ardingly Sandstone.

[1] Stone Farm and Harrisons Rocks are managed by the British Mountaineering Council (BMC).

The rock is particularly soft and care needs to be taken to prevent erosion.
