Definition
An "alluvial cone" is similar to an alluvial fan, but steeper and more cone-shaped. Imagine the same process of a stream depositing sediment, but with a higher gradient or smaller area for spreading. This results in a conical accumulation of material, rather than a fan-shaped one. Alluvial cones often form in mountainous regions with limited space for sediment to spread out. Think of it as a more concentrated alluvial deposit. ⛰️
