Charles Preuss Maps of 1846. Denver: Nolie Mumey, 1852. Seven facsimile maps and text and portrait issued in original (folded) paper covers. Limited to 150 signed copies, of which this is number 59. Very good condition.
Charles Preuss accompanied J.C. Fremont as his cartography on three of his important expeditions to the west. In 1846, Charles Preuss produced a seven sheet map based on “the field notes of Capt. J.C. Fremont and from sketches and notes made on the ground by his assistant, Charles Preuss” during the expeditions of 1842-43. They show, in amazing detail, the route from Westport, on the Missouri River, to the mouth of the Walla Walla River in Oregon. Each map shows abotu 250 miles of the route and they capture essentially the Oregon Trail during its seminal period.
