What is a bajada?
Quick Answer
A bajada is a broad slope of overlapping alluvial fans along the base of a mountain front in a desert.
The Full Story
A bajada forms when separate alluvial fans merge into one long apron of sediment at the foot of a mountain range. It develops where short-lived streams carry sand, gravel, and silt out of steep canyons and spread them across the valley floor. Bajadas are common in dry regions because sporadic flash floods move large amounts of debris in brief bursts. The word comes from Spanish and means “slope” or “descent.”
