1950 Map of Alleghany
USGS Topo · Published 1980About this map
Sixteen to One Mine and the Plumbago Mine anchor this mid-century survey of the California gold country where Sierra and Nevada counties meet. The landscape is defined by the extensive hydraulic mining scars of the Malakoff Diggings, Alpha Diggings, and Omega Diggings, illustrating the scale of 19th-century industrial extraction along the Middle Fork Yuba River. Settlements like Alleghany, North Bloomfield, and Washington are shown alongside smaller family landmarks and rural infrastructure, including Clerkins Ranch, the Blue Tent School, and the White Cloud Guard Sta.
