(West) ... New Mexico and the Southern Rocky Mountains

(West) Map Showing the Route pursued by the Exploring Expedition to New Mexico and the Southern Rocky Mountains made under the orders of Captain J.C. Fremont U.S. topographical engineers and conducted by Lieut. J.W. Abert, assisted by W.G. Peck, U.S.T.E. during the year 1845This map is from Abert’s report of the Expedition to the upper Arkansas River. He made the first astronomical observations in this unknown country and the map (thus sayeth Wagner-Camp), “is therefore of great importance”. It covers the area from Missouri to the Rockies as far north as Fort Laramie and south to Santa Fe. In additional to their own observations, the lieutenants drew upon other sources including “information obtained from the Comanchee (sic) and Kiowa Indians”. The final product was probably prepared for publication by Charles Preuss. Of particular interest, the map shows the entire route of the Santa Fe Trail, noting the locations of Council Groves and Pawnee Rock along the way. Wheat 489.Condition i
