Anderson Scarp
Anderson Scarp () is an upward slope and cliff high, about west of Hall Bluff on the Dais, Wright Valley, in the McMurdo Dry Valleys of Antarctica. It was named by the Advisory Committee on Antarctic Names in 2004 after Kent Anderson of the Albuquerque Seismological Laboratory, U.S. Geological Survey, from 1992. He played a key role in the installation of the VNDA seismograph station at Bull Pass, near Lake Vanda Lake Vanda is a lake in Wright Valley, Victoria Land, Ross Dependency, Antarctica. The lake is long and has a maximum depth of . On its shore, New Zealand maintained Vanda Station from 1968 to 1995. Lake Vanda is a hypersaline lake with a salin ..., in the early 1990s.

Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ...
