1873 Map of North America Delineating the Mountain System and its Details, the Great Calcareous Plain as a Unit, and the Continuous Encircling Maritime Selvage
DESCRIPTION
A fascinating and boldly colored interpretation of North American geography, created by William Gilpin to demonstrate how the continent's mountain systems, immense interior plain, and coastal regions formed an interconnected physical whole.
Published in 1873, the map extends from the Arctic to Central America and combines detailed contemporary cartography with broad areas of hand coloring that transform familiar geography into Gilpin's distinctive interpretation of the continent. Two enormous red circles further emphasize the interior zone that he believed occupied a privileged position within North America's physical and climatic structure.
Mountains, Plains, and the Maritime Selvage
The printed title identifies the three principal components of Gilpin's theory: the “Mountain System and its Details,” the “Great Calcareous Plain as a Unit,” and the continuous encircling “Maritime Selvage.” Here the vast interior plain stretching through central Canada and the United States is treated as a single geographic region, while the Rocky Mountains, Sierra Nevada, Mexican highlands, and other western ranges are differentiated into individual components. Coastal regions complete Gilpin's continental framework, creating the maritime belt surrounding the interior.
The map's unusual coloring makes Gilpin's theories immediately visible. Rather than merely distinguishing political boundaries, color groups vast portions of the continent according to the geographic relationships he sought to demonstrate. States, territories, rivers, cities, mountain ranges, and transportation routes remain visible beneath these broad zones, creating an intriguing mixture of conventional cartography and geographic theory. The result is a map intended not simply to locate places, but to explain how Gilpin believed the physical structure of North America would shape settlement and economic development.
William Gilpin and His Vision of the West
The map is closely associated with William Gilpin (1813–1894), Colorado Territory's first governor and one of the nineteenth century's most enthusiastic advocates for the settlement and development of the American West. Gilpin viewed the Rocky Mountains not simply as an obstacle to migration but as the geographic backbone of a future continental nation. His ideas combined geography with an expansive vision of Manifest Destiny, agriculture, population growth, and especially transcontinental railroads that would connect the interior with the rest of the country.
Published as one of six maps accompanying his Mission of the North American People, this sheet transforms physical geography into a persuasive cartographic expression of Gilpin's ambitious vision for North America's future.
