The Hayden Survey, officially known as the United States Geological and Geographical Survey of the Territories, was one of the major government-sponsored surveys of the American West undertaken in the post-Civil War era. Led by geologist Ferdinand Vandeveer Hayden, the survey began in the late 1860s and was formally established under congressional authorization in 1867. Its work continued through 1879, when it was merged into the newly created United States Geological Survey (USGS). The Hayden Survey was instrumental in charting vast and largely undocumented western territories, particularly focusing on the Rocky Mountains, Yellowstone, and other key regions. It was one of four great surveys of the West alongside those led by Clarence King, John Wesley Powell, and Lt. George Wheeler.
Cartographically, the Hayden Survey made significant contributions to the mapping of the western territories. It relied on both field sketching and triangulation methods to produce detailed topographic and geological maps. Among the key cartographers on Hayden’s team was Anton Schönborn, a skilled draftsman and topographer whose work helped translate field data into precise and visually sophisticated maps. The survey’s maps combined aesthetic clarity with scientific rigor, helping to set new standards for American cartography in the 19th century. These maps not only facilitated westward expansion but also provided data for understanding geology, hydrology, and natural resources.
The survey was also deeply visual in nature, thanks in large part to the work of photographer William Henry Jackson and artist Thomas Moran. Jackson’s pioneering photographs were among the first ever taken of Yellowstone and other remote locations, providing the public and policymakers with striking visual evidence of the grandeur and uniqueness of the landscape. His images played a vital role in convincing Congress to establish Yellowstone as the first national park in 1872. The visual documentation by Jackson and Moran bridged science and art, lending emotional and aesthetic weight to the survey’s scientific findings.
Historically, the Hayden Survey holds immense value as a foundational effort in the scientific exploration of the American West. It laid the groundwork for future geological and environmental studies and helped shape federal land policy. By combining cartography, photography, geology, and natural history, the survey reflected a broad interdisciplinary approach that was ahead of its time. It also marks an important moment in the history of U.S. governmental science and remains a key chapter in the narrative of westward expansion, conservation, and the mapping of the American landscape.
