Striking example of the first edition David Burr's map of Oregon Territory, which appeared in Burr's Universal Atlas. Rich with Indian information and details of the earliest settlments in Oregon Territory. This fascinating map was the only commercial atlas map to depict Oregon Territory on a separate map. Extending to 54 degrees 40 minutes, it reflects the then active dispute between the US and British interests over the region which would become the southern part of British Columbia, which were not resolved until a decade later. The discoveries of Lewis & Clark, the Hudson's Bay Company and John Jacob Astor's Company are in evidence, along with some of the fascinating early water routes from the Pacific to Salt Lake (Timpanagos) and other mythical pre-Fremont Cartography. An essential Northwest Map. Burr's Atlas utilized wonderful wash colors and elegant engraving style. Burr studied under Simeon DeWitt in New York. His first atlas was an Atlas of New York State, the second state atlas to be issued in the US (after Mills Atlas of South Carolina in 1826). In the 1830s, he served as topographer for the US Post Office, producing a series of rare and highly sought after large format state maps during this period. Later, he was appointed as the Geographer of the House of Representatives, where he served during the later part of the 1830s. Burr is widely regarded as one of the most important names in American Cartographic History. A fine example of this map, which rarely appears on the market.
