This colorful double-page map shows an early rendering of Wyoming Territory, organized in 1868. The territory's western boundary is not fully established, with a bulge extending above Idaho with Idaho occupying western Wyoming south of Jackson Hole. The map correctly delineates Montana which, along with Wyoming, was previously contained in a large Idaho territory. Dakota Territory, from which Wyoming was formed, remains undivided with county development confined to its eastern boundary along the Red River of the North. There is excellent detail throughout with scores of place names, wagon roads, rivers, topography, the Emigrant Road, forts, springs, routes of exploration, and proposed railroads. The route of the Pony Express & U.S. Mail Route through Utah, Wyoming and Nebraska is delineated. Dated 1865 and published in 1869.
