Tailings fans and valley-spur cutoffs created by hydraulic mining

Authors(s) and Affiliation(s)



Sand and gravel tailings from nineteenth century open-pit hydraulic gold mines formed large alluvial fans at tributary confluences in the northwestern Sierra Nevada, California. In the Bear River watershed, several of these fans were so large that they blocked main channels for decades. Some channels not only aggraded deeply, but also moved laterally and cut across the inner bends of valley spurs. Now locked in bedrock channels, these valley-spur cutoffs impose local controls on geomorphic, hydraulic, and sedimentary processes. This paper outlines the genesis and nature of these tailings fans and valley-spur cutoffs, and their geomorphic implications
