This survey, with those of See also:Ferdinand See also:Hayden (1829–1887) and See also:Captain See also:George M. See also:Wheeler (b. 1842) was incorporated with the See also:United States Geological and Geographical Survey under See also:Clarence See also:King (1842–1901) in 1879, when Powell became director of the See also:Bureau of See also:Ethnology, a See also:department he had assisted in See also:founding.

On King's resignation in 1881, Powell was appointed director also of the Geological Survey, a See also:

post which he occupied until 1894. To him the See also:present thorough organization of the U.S. Geological Survey is largely due. His See also:principal publications were Exploration of the Colorado River of the See also:West and its Tributaries (1875), See also:Report on the Geology of the Eastern Portion of the Uinta Mountains (1876), Report on the Lands of the Arid Region of the United States (1879), Introduction to the Study of See also:Indian Languages (188o), Canyons of the Colorado (1895), Truth and See also:Error (1898). Especially important were his observations on what is now termed the " Uinta type " of mountain structure: a broad, flattened anticline, from which the strata descend steeply into bordering See also:low grounds and quickly resume their horizontality—being sometimes faulted, and affording See also:evidence of enormous denudation. He died in Haven, See also:Maine, on the 23rd of See also:September 1902. • See F. S.
