A bajada may be created. A bajada is a broad, gently sloping surface formed by the coalescing of alluvial fans.
Alluvial fans can be found in several locations across California, particularly in desert regions and mountainous areas. One notable example is the alluvial fan at the base of the Sierra Nevada mountains, especially around the Owens Valley. Additionally, the Coachella Valley and parts of the Mojave Desert also feature prominent alluvial fans formed by sediment deposited by rivers and streams. These geological formations are characterized by their fan-shaped appearance, created as water flows down from higher elevations.
The braided markings on alluvial fans are from erosion caused by braided streams. It is created by the meandering, combining, and separating of the waters as they flow over and around different landforms.
