| Additional Notes | These strongly inclined and contorted beds of limestone above the fault scars on Barnarm Scar and at Mount Ida are the spectacular consequence of a long lasting series of uplift and dislocation of the Great Scar and Robinson Limestones which are the Lower Beds in the Carboniferous Limestone Series. These limestones, which now form the high edge of the Pennine Escarpment, once were buried deep below the Triassic red sandstones of the Vale of Eden. |
