Bank. Sea area of positive bottom relief where the water is relatively shallow, but normally sufficient for safe navigation. The term may also be applied to a small nunatak or other land feature.
Basin. Synonymous on land with cirque, or an almost landlocked body of water off an inlet or sound, but the term in English form in the latter sense does not arise in this work.
Bastion. Upstanding rock feature, often with cliffs on at least one side and usually outlying a larger feature, cf. buttress.
Bay. Properly a comparatively gradual indentation of the coast-line, the seaward opening of which is usually wider than the penetration into the land, but often applied more loosely, cf. bight, firth, fjord, gulf, inlet.
Beach. Ice-free length of shore, gently sloping and free of rock outcrops or material above cobble size.
Beacon. Conspicuous hill.
Bench. Similar to terrace but usually applied to a smaller feature.
Bight. Crescent-shaped indentation in the coastline, of relatively large extent, cf. bay.

Chain. Row of hills, mountains or nunataks of lesser extent than a range.
Channel. A comparatively deep, navigable waterway between an island (or islands) and the mainland, or between islands, or a navigable route through shoals, cf. strait, although the distinction between the two terms has not always been maintained as an application.
Chasm(s). Synonymous with large crevasse.
Cirque. Rounded recess on a mountain side formed by glacial action and usually occupied by a glacier.
Cliffs. Relatively high land projecting nearly vertically from the sea or, inland, mountains or nunataks with vertical faces.

Foreland. Synonymous with headland.
Gap. Synonymous with pass.
Glacier. Mass of snow and ice moving continuously from higher to lower ground or, if afloat, continuously spreading. In the broad sense, glaciers include ice caps, ice piedmonts, ice rises, ice shelves, ice streams and snowfields, but in place-names the term is restricted to features of valleys or cirques.

Plug. Volcanic neck.
Point. Sharp and often comparatively low piece of land jutting out from the coast or forming a turning point in the coastline, but usually applied to a less prominent or less navigationally significant feature than a cape. The term may also be applied to a rock feature at a little distance from a low ice-covered coast.
