These remarkable pictures show the American West as it was explored for the first time. Taken by photographer Timothy O’Sullivan who worked with a Federal Government team as they explored the American West. He had earlier covered the U.S. Civil War and was one of the most famous photographers of the 19th century.
At the time federal government officials were travelling across Arizona, Nevada, Utah and the rest of the West as they sought to uncover the land’s untapped natural resources.
He also took pictures of the Native American population for the first time as a team of artists, photographers, scientists and soldiers explored the land in the 1860s and 1870s.
