All (92) major hydraulic placer gold mines and major drift mines that were mined over the last 170-year period are shown on the map by locality and georeferenced Index List.

Ancestral Yuba River – main channel and major tributaries are depicted, as well as paleo-channel flow-directions.

A simple Georeference Index System is displayed on the map borders.

All (68) historic townsites related to the development of placer gold resources within this ancient 50 million year-old paleo-river system and also shown on the map by locality and georeferenced Index List.
