Nice map of California and Nevada with topographic detail, which appeared in the 1870s in atlases by Warner & Beers.
The map is colored by county. Shows towns, railroads, roads, rivers, mountains, dry lakes, Indian tribes, etc.
Pre-dates the creation of Orange, Imperial, and Riverside counties in Southern California as well as Modoc and San Benito in Northern California.
Original hand-color by county. Minor soiling in bottom margin.
