Bajada (geography)
A bajada consists of a series of coalescing
alluvial fans along a mountain front. These fan-shaped deposits form by the deposition of sediment within a stream onto flat land at the base of a mountain.[1] The usage of the term in landscape description or geomorphology derives from the Spanish word bajada, generally having the sense of "descent" or "inclination".[2]
Formation and occurrence
When a stream flows downhill, it picks up sediment along with other materials. As this stream emerges from a mountain front, the sediment carried begins to be deposited, such that coarser sediment is deposited closest to the base and the finer sediment grades outwards and deposits in a fan-shape away from the mountain face.
