in 1853, where he attracted the notice of Professor James Hall, state geologist of New York, through whose influence he was induced to join in an exploration of Nebraska Territory, with Fielding B. Meek to study geology and collect fossils. Hall sent him on his first geological venture in the summer of 1853. Being of independent mind Hayden ended his commission with Hall, and with the encouragement of S. F. Baird, and a partial sponsorship from the Smithsonian Institution, he spent the remainder of the 1850s on various exploring and collecting expeditions in the northern Missouri River areas. In 1856 and 1857, Hayden accompanied exploration expeditions led by Lieutenant Gouverneur K. Warren and in 1859, the Raynolds Expedition of 1860 led by Captain William F. Raynolds, both of the Topographical Engineers. One result of the expedition was his ''Geological Report of the Exploration of the Yellowstone and Missouri Rivers in 1859–1860'' (1869). During the

he served as an army surgeon. He rose to be chief medical officer of the Army of the Shenandoah and received a brevet to lieutenant colonel.

Geological surveys

After the American Civil War Hayden led geographic and geologic surveys of the Nebraska and Western Territories for the United States Government. In 1867 he was appointed geologist-in-charge of the

United States Geological and Geographical Survey of the Territories The United States Geological and Geographical Survey of the Territories was established by an act of Congress on 2 March 1867 as an agency under the Department of the Interior (later the General Land Office) tasked to complete a geographical surv ...

. Hayden organized and led previous expeditions into the Rocky Mountains, both before and after the Civil War. In 1869, he led an expedition along the Front Range to Denver and Santa Fe. In 1870 he received a $25,000 governmental grant to lead a 20-man expedition to South Pass, Fort Bridger, Henry's Fork, and back to Cheyenne. About this time, he also became identified with the Megatherium Club at the Smithsonian Institution in Washington, D.C. To measure distances during their journeys into the western frontier Hayden employed the use of an

odometer An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two ( electromechanical). The noun derives from ancient G ...

, a device used by mappers to estimate distances traveled. The device was mounted on a mule-drawn cart that measured distances as the cart wheels rolled along. Because of rough terrain the device was accurate to within about 3%.

Legacy

From his twelve years of labor and annual survey journeys there resulted a most valuable series of volumes in all branches of natural history and economic science; and he issued in 1877 his ''Geological and Geographical Atlas of
