cliff face

plural cliff faces

1. The very steep, vertical, or overhanging section of rock, earth, or ice slope usually free of any vegetation or loose material.

   Commencing next summer, 30,000 tonnes of cliff face will be removed, and mesh-and-bolt caging installed on a three-mile section to stabilise the surface and prevent rock falls.

   Using the countless tons of rock from the cliff-face, supplemented by much more from inland, they threw out a huge breakwater, 2,000 ft. long and 80 ft. high, roughly at right angles to the quay, so forming an almost completely sheltered corner. Fifty years later, this massive mole is still standing up to the worst that the Irish Sea can do.
