What kind of site this is
GRAVEL ON BEDROCK · GOLDSLUICESECTION · ILLUSTRATIVE

Drawn as a placer working, where loose gold-bearing gravel is washed rather than dug from rock. The ore color stands for gold. Federal records note the kind of operation and its status, not its depth or layout, so this is a typical example rather than a survey of this site.
