Hayden Geological Survey

Hayden Geological Survey


In 1871, the US government sent Ferdinand Hayden with a survey team on an expedition to document the area that would soon become Yellowstone National Park. They took temperatures, recorded information, wrote articles for newspapers, and collected samples of geology and botany. After the expedition was over, Hayden was influential in persuading Congress to establish Yellowstone National Park by advocating for its protection and sharing his reports and samples.

After stopping at Fort Ellis and gathering supplies, Hayden's party departed for the Yellowstone area on July 15, 1871.

Thomas Moran's diary, National Park Service

Hayden brought two artists on his expedition, painter Thomas Moran and photographer William Jackson, to provide visual representations of Yellowstone, crucial to establishing the national park. Many people in the East didn't believe the stories of the natural wonders within Yellowstone, however, by taking photographs and painting scenes, many people were convinced, adding to the environmental rights movement. Without the art provided, it's possible Yellowstone might not have been established for many years. 

"But I have always held that the grandest, most beautiful or wonderful in nature would in capable hands, make the grandest, most beautiful or wonderful pictures; and that the business of a great painter should be the representation of great scenes in nature."

-Thomas Moran, painter on the Hayden Geological Survey

By sharing the art created on the expedition, the public's imagination was captured, sparking their interest in the national park idea.
