This colorful double-page map shows a very early rendering of Wyoming Territory, organized in 1868. Idaho is shown taking up the present-day Wyoming region south of Jackson Hole. With the exception of the southwestern border, Montana is correctly formed which, along with Wyoming, was previously contained in a large Idaho territory. Dakota Territory, from which Wyoming was formed, remains undivided. There is excellent detail throughout with scores of place names, roads, watershed, 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. The map retains the 1865 copyright date, but was published circa 1868.
