Based largely on the work of De Mofras and Fremont, this map adds the large gold region of California, shown by a shaded area. The map extends to east of the Rockies and the continental divide, south into Sonora and part of Baja, and well into Oregon Territory to the west. Many place names and Indian regions are noted. Wheat says this map "was about as up-to-date as it could have been in early 1850." Charming vignettes of Indians and wild animals are scattered about the map. A rather scarce issue.
