Rare Geological & Mining Map of Nevada.
Highly detailed map of Nevada, colored by Geological and Mineralogical regions and showing mines, mineral deposits, salt deposits, railroads under construction and the route taken by Guillemin-Tarayre through Nevada.
There are also sevearl Indian encampments noted, along with towns, rivers, mountains, etc.
Guillemin-Tarayre's map is part of a rare set of scientific works published by the French government. The map illustrated a section which relates to geology and mining in California and Nevada. In 1864, as a result of a French military expedition to Mexico, the Commission Scientifique du Mexique was established. At the time, mining in California and Nevada were the focal point of a great deal of interest in Europe.
The map is very rare. This is the first separate example we have ever seen on the market.
