California and Nevada in 1871 - Virginia City, Truckee, Sacramento

Edmond Guillemin-Tarayre prepared this general map of California and Nevada in 1867, published in Paris in 1871 by France's Commission Scientifique du Mexique as a companion sheet to the same mission's geological and metallurgic plates of the two states. Where those related maps overlay mineral and rock data onto the landscape, this base sheet presents the region's towns, rivers, lakes, and administrative geography on its own, the very foundation Guillemin-Tarayre and his engravers built the mission's more technical plates upon. The map is one of seventeen plates bound into an obscure two-hundred-sixteen-page volume on the geology of California and Nevada that, oddly, breaks off mid-sentence partway through a hyphenated word, evidence of just how hastily the mission's findings were rushed into print. Compiled from the latest documents available to the French scientific mission, the sheet reflects the same rush of American and European interest in the Comstock Lode and California's mining districts that drove the entire publication.

Virginia City and the surrounding Washoe Valley anchor the map's Nevada coverage, the boomtown that had sprung up almost overnight after the 1859 discovery of silver at the Comstock Lode. Truckee appears as the railroad town that grew up specifically to serve the new line connecting the mining district to the broader rail network, a connection this base map was compiled in part to document. Towns, rivers, and lakes are identified across California in the same careful detail, alongside county names, even though the map stops short of drawing formal county boundaries. This base geography underpins the mission's companion geological and metallurgic plates directly, giving collectors of all three sheets a shared reference point across the set.

This map suits a California or Nevada family with roots in the silver rush era, someone with a particular interest in Truckee's origins as a railroad town, or a collector building out the full set of the French mission's California and Nevada plates. Alongside the Vault's companion geological and metallurgic sheets from the same 1871 publication, this base map is distinguished as the plain geographic foundation beneath both, valuable on its own for its town and river detail without the specialized overlays. It's available unframed in a full range of sizes, from a compact study print to a larger statement piece.
