Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a transition from one series of sedimentary rocks to another series of a different age and composition. Escarpments are ...
The Bluff Formation consists of massive wind-deposited sandstone beds at its type location at Bluff, Utah. These cap the cliffs north of town and are 100–350 feet (30–107 m) thick. [ 1 ] Further to the southeast, the sandstone beds lack high-angle cross beds , being dominated instead by horizontal bed forms, and are overlain by mixed ...
Most of the bluff is displaced approximately 40 metres (131 ft) upwards relative to the adjoining bedrock along the Red Wing Fault, which transects the bluff near its south face. It is composed of early Paleozoic rocks, including Ordovician dolomite and sandstone atop Cambrian shale , siltstone and greensand at its base, deposited by early ...

The large Bloody Bluff Fault (named for Bloody Bluff in Minute Man National Historical Park in Lexington) is a west-dipping brittle deformation zone that formed between the Avalon terrane and Nashoba terrane, likely in the late Paleozoic.
Gosses Bluff (or Gosse's Bluff) is thought to be the eroded remnant of an impact crater. [2] [3] [4] Known as Tnorala to the Western Arrernte people of the surrounding region, it is located in the southern Northern Territory, near the centre of Australia, about 175 km (109 mi) west of Alice Springs and about 212 km (132 mi) to the northeast of Uluru (Ayers Rock).
Niagara Escarpment (in red) Rattlesnake Point near Milton, Ontario The Niagara River has carved the Niagara Gorge through the Niagara Escarpment over thousands of years. The Niagara Escarpment is a long escarpment, or cuesta, in Canada and the United States that starts from the south shore of Lake Ontario westward, circumscribes the top of the Great Lakes Basin running from New York through ...
A rock shelter (also rockhouse, crepuscular cave, bluff shelter, or abri) is a shallow cave-like opening at the base of a bluff or cliff. In contrast to solutional caves ( karst ), which are often many miles long or wide, rock shelters are almost always modest in size and extent.
