in early 1859, placer gold was found fifteen miles above fort yuma at the "pot holes" on the west bank of the colorado river. placer mining in the area continued into the later 19th century. dredging the colorado river for gold in the vicinity of pot holes was attempted in 1900-1901, but it was a failure. most of the gold was too fine to be caught in the mechanism of the dredge used.
