Original large-format fold-out edition of Map of a Reconnoissance Between Fort Leavenworth on the Missouri River, and the Great Salt Lake in the Territory of Utah. Made in 1849 and 1850 under the orders of Col. J.J. Albert, chief of the Topographical Bureau, by Capt. Howard Stansbury of the Corps of Topographical Engineers, aided by Lieut. J.W. Gunnison and Albert Carrington. Drawn by Lieut. Gunnison and Charles Preuss.

• This immense map, which opens to more than five feet across and is drawn on an approximate scale of one inch to sixteen miles, is one of the most important in the cartographic history of the American West.



• The map traces the routes followed by Stansbury, Gunnison, and Carrington, with dates at various points along their travels and early place names and points of reference on their expedition through the territories of Nebraska, Colorado, and Utah.



• Rivers and topography are shown in fine detail and the map locates numerous forts and Indian tribes.



• Labeled forts include Fort Hall, Fort Laramie, Fort Leavenworth, and Fort St. Vrain.



• Labeled Indian tribes include the Sioux, Utah, Snake, Pawnee, Arapahoe, and Cheyenne.



• The map also shows the street grid of Salt Lake City, founded July 24, 1847, by early pioneer settlers led by Brigham Young.



• The map folds into stiff, decorative blindstamped leather covers with gilt embossed lettering on the front. The covers measure 24 x 16 cm [9½" x 6¼"], and the map itself unfolds to a massive 75 x 170 cm [29½" x 67"].



• Condition:  This map has been cleaned, deacidified, and backed. It is in excellent condition, with a bright, crisp impression, a few tiny areas of paper loss at a couple of the folds, and no marks, rips, or tears. The cover boards are also in fine shape, with strong corners and faint spotting. Please see the scans and feel free to ask any questions.



• This map had been published in 1852 as part of Stansbury's report to Congress on the exploration and survey Of the valley Of the Great Salt Lake and evaluation of a possible railroad route through the Rocky Mountains. It had originally been accompanied by a smaller, companion map. Please note that the companion map and the report itself are not present.
