Decorative map of the region, hand colored by counties, with two marvelous insets, one of the Yosemite Valley and the other showing the Big Trees of the Sequoias in Mariposa County, California. The map includes towns, railroads and stations, lakes, rivers, mountains, mines, wells, and a host of other details. The vivid coloring is a hallmark of Tunison's early atlases. Many early counties still do not appear. A marvelous decorative map.
