If you look closely, you‘ll notice that this apron of sediment is actually composed of many individual, fan-shaped deposits, each radiating from a deep canyon cut into the mountain front. Death Valley is world-famous for the incredible size, shape, and exposure of these alluvial fans.
At the mouth of Golden Canyon, you are standing on another alluvial fan. Here you can see evidence of how past floods have shaped this fan. Look closely at the rocks nearby, including those that you are standing on. What do you notice about their size? You may notice that large boulders and cobbles have been deposited near the entrance of the canyon. Try to imagine the force of the floods required to move some of these larger boulders!

Flash floods emerging from the narrow, confining walls of Golden Canyon suddenly spread out at the canyon mouth into the open valley below. As the torrent slows down, the water is no longer able to carry its load of sediment, and rapidly deposits a chaotic mixture of poorly sorted debris on the alluvial fan. Farther downslope toward the valley floor, the sediment becomes progressively smaller.
