alluvial fan --
An alluvial fan is a fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plain. A convergence of neighboring alluvial fans into a single apron of deposits against a slope is called a bajada, or compound alluvial fan.(AGI, 37-8)

I used to work in Death Valley National Park. When rocks wash down from the mountains they 'fan out' onto the desert floor. We called this an 'alluvial fan'.

It is a river or other water channel mouth that leaves a "fan" of debris from the flowing water. The Mississippi delta is a good example that you can see in a satellite photo. The heaviset pices drop first, then the lighter ones drop further out in the fan shape.
