This large folding map was printed by Sarony, Major and Knapp and is hand colored from the Gold Region south to show primitive geological units. Also shows much other interesting detail, especially along the American River. Lake Tahoe is not shown - rather there is a very small lake that carries the name Lake Bonpland.
Good impression and color. A few scattered spots, folding as issued.
