This uncommon map features an interesting configuration of western territories. Dakota Territory is yet to be organized, with the large Minnesota Territory extending to the Missouri River. A huge Nebraska Territory extends west from the Missouri River to the Continental Divide where it meets the oversized Oregon Territory, and south all the way to Texas and Indian Territory. The Texas panhandle spans north to the Arkansas River, with a small sliver crossing well into present-day Colorado - a surprising feature given the map's date. The large Utah Territory stretches between California and Nebraska, encompassing present-day Nevada and Colorado. New Mexico Territory features the pre-Gadsden Purchase border. There is good detail of topography and watershed, and many place names.
