An attractive map based on Hall's earlier map of 1829-30 with full color added to reflect geological formations, volcanoes, etc. A legend explains the use of color. The geographical aspects of the map show nice place name detail and have been updated to delineate Oregon Territory [created in 1848], and Utah Territory [created in 1850]. Washington Territory [created in 1853] does not show. Folds and linen backing indicate this map was a separately issued pocket map in octavo format, rather than from the New General Atlas as normally found. Fine keyboard border.
