bajada

Geology and Earth Sciences

Extensive, gently sloping plain of unconsolidated rock debris resting against the foot of a mountain front in a semi-arid environment. Typically it is made of a number of coalescing alluvial fans laid down by ephemeral streams as their gradients lessen on leaving the mountain zone. Material is also supplied by the weathering of the mountain front. Alternatively, it may comprise the alluvial accumulation on the lower part of a pediment.

Geography

A series of alluvial fans, typically laid down by ephemeral streams, which has coalesced along the foot of the mountains to form a gently sloping plain of unconsolidated sediments. The weathering of the mountain front may also supply debris. Alluvium on the lower part of a pediment may also make a bajada. See Bull’s classic paper (1977), PPG 1; Leeder and Mack (2001) J. Geol. Soc. 158 for a clear review, plus a great title; and Wainwright et al. (2002) J. Arid Envs. 51.
