Description

Fine example of Colton's map of Wyoming, Colorado and Utah, pre-dating the addition of Yellowstone Park.

Wyoming is shown with only 5 counties. The progress of the General Land Office Surveys can be shown along major rivers, but large parts of the 3 territories are unsurveyed. The Union Pacific Railroad line has now traversed the country via Wyoming, with a number of other lines shown in Utah and Colorado.

The mining boom in southwestern Colorado is much in evidence, with Telluride, Silverton Ohir, Ouray and other early boom towns shown, although the railroad has only reached Lake City.

G.W. & C.B. Colton Biography

G. W. & C. B. Colton was a prominent family firm of mapmakers who were leaders in the American map trade in the nineteenth century. The business was founded by Joseph Hutchins Colton (1800-1893).  who bought copyrights to existing maps and oversaw their production. By the 1850s, their output had expanded to include original maps, guidebooks, atlases, and railroad maps. Joseph was succeeded by his sons, George Woolworth (1827-1901) and Charles B. Colton (1831-1916). The firm was renamed G. W. & C. B. Colton as a result. George is thought responsible for their best-known work, the General Atlas, originally published under that title in 1857. In 1898, the brothers merged their business and the firm became Colton, Ohman, & Co., which operated until 1901, when August R. Ohman took on the business alone and dropped the Colton name.
