Description

ONLY ONE I HAVE!!
This is USGS Bulletin 955-F,
Quicksilver Deposits of the Bonanza-Nonpareil District, Douglas County, Oregon.
Published in 1951, it consists of a 29-page book AND ALL TEN OF THE ORIGINAL MAPS, one of which is a two-color map in red and green. This scarce report details this productive mercury mining district. Minerals from this area include:
Cinnabar
Native mercury
Metacinnabar
Calomel
Realgar
Orpiment
Melanterite
Calcite
Siderite
Marcasite
Mines in the area include:
Bonanza mine
Nonpareil mine
(which is divided n to the north and south mines)
Butte prospects
Sutherland prospects
The maps show underground workings and surface geology in the area, and the text does a good job tying it all together. This would make a great guide to this historic area, where the first discoveries were made in the mid-1800s. Note that one of the maps actually is printed in red and green - It is
not
a poor photo!
Expert packing assured. The recent increase in postage rates was pretty big. As a result, Media Mail is now my default shipping method to keep shipping affordable.
