Here is link to some great pictures taken by Timothy O'Sullivan, who used a box camera, worked with the Government teams as they explored the land. He had earlier covered the U.S. Civil War and was one of the most famous photographers of the 19th century.
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.
The images of the landscape were remarkable - because the majority of people at the time would not have known they were there or have ever had a chance to see it for themselves.
O'Sullivan died from tuberculosis at the age of 42 in 1882 - just years after the project had finished .
He carted a dark room wagon around the Wild West on horseback so that he could develop his images. He spent seven years exploring the landscape and thousands of pictures have survived from his travels.
