1836 A Map of a Portion of the Indian Country Lying East and West of the Mississippi River to the Forty Sixth Degree of North Latitude from Personal Observation Made in the Autumn of 1835 and Recent Authentic Documents.

A fascinating and highly important government survey map of the Upper Mississippi Valley and western Great Lakes region, this large-scale work documents the rapidly changing political and geographic landscape of the American frontier during the mid-1830s, only a few years after Chicago was incorporated as a town in 1833. Prepared from George William Featherstonhaugh’s personal observations made during his 1835 reconnaissance for the United States Topographical Bureau, the map captures a vast territory stretching from present-day Illinois and Wisconsin westward into Iowa and Minnesota at a moment when federal expansion, Native land cessions, mining development, and the fur trade were reshaping the interior of North America. The map preserves an exceptionally early view of settlement and administration in the Upper Midwest. Along Lake Michigan, the “Milwaukee District” appears years before Milwaukee was formally incorporated as a city in 1846, while farther inland the “City of the Four Lakes” marks the embryonic settlement that would soon become Madison, Wisconsin. The lead-mining center of the “Galena District” is prominently identified in northwestern Illinois and southwestern Wisconsin, reflecting the explosive mineral economy that drew thousands of settlers into the region during the 1820s and 1830s. Chicago itself appears as a small frontier settlement and is not yet connected to the greater river system via the Illinois & Michigan Canal, construction of which would begin the following year in 1836. Completed in 1848, the canal linked the Great Lakes to the Mississippi watershed and transformed Chicago into one of the principal commercial arteries of the American interior, funneling manufactured goods westward while carrying grain, lumber, lead, and other raw materials from the expanding frontier back toward eastern markets. Native Territories, Treaties, and Federal Expansion One of the map’s most compelling aspects is its detailed portrayal of Indigenous territories and treaty cessions during a period of accelerating American expansion. Large regions are labeled for the Winnebagoes, Menomonies, Chippewas, Ottawas, and Pottawattamies, while the western portions of the map delineate the “Sioux Cession to the U.S.” and the “Sac and Fox Cession to the U.S.” concluded at Prairie du Chien on July 15, 1830. Nearby, the map records a massive “5,000,000 Acres” reserved for the “Chippewas Ottawas and Pottawattamies,” offering a stark visual reminder of the treaty-driven redistribution of Native lands occurring throughout the Old Northwest. The map also identifies lands “Ceded to U.S. for Indian Purposes” west of the Mississippi, along with the “New Purchase” in present-day Missouri, illustrating the federal government’s shifting policy of removing eastern tribes westward while simultaneously negotiating away lands farther north and west. Particularly noteworthy is the appearance of the “New York Indians” in Wisconsin, referring to displaced Indigenous groups from the northeastern United States who had been relocated into the region during the early nineteenth century. Together, these labels reveal a frontier in transition, where overlapping claims, removals, and negotiations produced an unstable and rapidly changing territorial landscape. Exploration, Rivers, and the Fur Trade The upper portions of the map contain a remarkable concentration of geographic detail derived from Indigenous knowledge, traders’ reports, and early government reconnaissance. Rivers, lakes, and portages throughout the upper Mississippi watershed frequently preserve phonetic spellings of Native place names alongside English translations or adaptations, providing valuable insight into how American surveyors attempted to record Indigenous geography. The map also identifies specific Dakota village sites such as “Little Crow’s Village” and “Iron Cloud’s Village,” preserving the locations of important Mdewakanton Dakota communities along the upper Mississippi during the decades before large-scale American settlement transformed the region. In the far northwest, numerous locations associated with the American Fur Company appear along rivers and trading routes, emphasizing the continuing dominance of the fur trade economy in the region prior to widespread agricultural settlement. Among the more evocative notations is the description of a “narrow passage with lofty mural sandstone banks,” referring to the dramatic sandstone formations of the Wisconsin Dells along the Wisconsin River. Such annotations demonstrate Featherstonhaugh’s interest not only in political boundaries and settlement patterns, but also in the geological and physical character of the country. Elsewhere, the map carefully traces tributaries, lakes, portages, and travel corridors extending deep into the interior, many of which remained known primarily through Native and fur trade networks rather than formal American settlement. The Half-Breed Tract and Frontier Land Claims The map additionally records several unusual frontier land arrangements that illustrate the complexity of early western expansion. Near the junction of the Mississippi and Des Moines Rivers appears the “Half Breed Tract,” a federally designated reservation established for individuals of mixed Native American and European ancestry. The tract became one of the most contested land regions in the early Midwest, plagued by unclear titles, speculation, and overlapping claims. Nearby, “Carver’s Grant” references the controversial and ultimately disputed land claim associated with explorer Jonathan Carver, whose alleged eighteenth-century grant from the Dakota remained the subject of debate well into the nineteenth century. Prepared at a formative moment in the development of the Upper Midwest, Featherstonhaugh’s map stands among the earliest large-format federal surveys to synthesize Indigenous geography, treaty boundaries, geological observation, military reconnaissance, and frontier settlement into a unified representation of the region. Few maps so effectively capture the complex intersection of Native sovereignty, mineral exploitation, federal expansion, and commercial enterprise that defined the Upper Mississippi Valley during the decades immediately preceding organized territorial government across Wisconsin, Iowa, and Minnesota.
