FEATURED MAP OF THE DAY
A New Map of Texas, Oregon and California (1846)
by Samuel Augustus Mitchell
As the country expanded westward, the boundaries of the country and its territories and states were in a constant state of change. This 1846 map of the western half of the country shows the political geography of the west on the eve of the Mexican-American War. Texas (annexed by the US in 1845) is shown extending north and west into parts of present-day New Mexico and Colorado. California, then still under Mexican control, consisted of the present-day states of California, Nevada, Utah, and parts of Arizona and New Mexico. The northern boundary of the territory of Oregon, which consisted of present-day Washington, Oregon and Idaho, had not yet been established. Both the boundary preferred by the British (along the Columbia River) and that preferred by the US (along the 49th parallel) are shown. The land north of Texas extending to the border with Canada is shown as three large territories: Missouri (parts of present-day Montana, Wyoming, North Dakota, South Dakota, and Nebraska), Iowa (parts of present-day North Dakota, South Dakota, Minnesota and Iowa), and Indian Territory (parts of present-day Colorado, Nebraska, Kansas and Oklahoma). The map also includes many well-known routes, including the Oregon Trail, Lewis and Clark's route, the Santa Fe Trail, and the Old Spanish Trail.
