Too close for comfort — Members of Ferdinand Hayden's Survey stand precariously close to Yellowstone National Park's Old Faithful Geyser erupting, circa 1878.
One of the Great Surveys of the West, the Hayden Survey (1867-79) systematically surveyed and mapped Western geology and geography. The Hayden Survey was conducted in Colorado during the field seasons of 1873 and 1876, and in Wyoming and Idaho during 1877 and 1878. A total area of 107,000 square miles was covered.
In 1871, Hayden presented a plan for the geological and geographical exploration of the territories of the United States. Congress approved and increased the appropriation, and changed the name to the U.S. Geological and Geographical Survey of the Territories. The scene of activities became Montana and one important result of that season’s field work was the creation of Yellowstone National Park.
Members of the team included Thomas Moran, an artist, Albert Peal, a mineralogist, George Allen, a botanist and William Henry Jackson as the team's photographer. ⛏
