slides, documents, letters, maps, and mining publications
surrounding the efforts of a California mining engineer and his
family reopening and mining the Davis Motor Mine, a
hydraulic/underground mining claim located in Sierra County,
California, between the ghost town of Port Wine, and Queen City,
near present day La Porte in the late 1960s.
The Davis Motor Mine was a hydraulic/underground gold mining
operation 35 miles from the California Ghost town of Port Wine,
and was originally filed on Nov. 11, 1909, by unknown owners on
the Sierra County, CA Assessor's Map. The Placer Claim Deed form
here in the archive notes that all the interested parties,
including Isabel Barquist's mother and brothers, are all listed
on the form as owners.
