Washburn–Langford–Doane Expedition

The Washburn Expedition of 1870 explored the region of northwestern Wyoming that two years later became Yellowstone National Park. Led by Henry D. Washburn and Nathaniel P. Langford, and with a U.S. Army escort headed by Lt. Gustavus C. Doane, the expedition followed the general course of the Cook–Folsom–Peterson Expedition made the previous year.

During their explorations, members of the party made detailed maps and observations of the Yellowstone region, exploring numerous lakes, climbing several mountains, and observing wildlife. The expedition visited both the Upper and Lower Geyser Basins, and after observing the regularity of eruptions of one geyser, decided to name it Old Faithful, since it erupted about once every 74 minutes.

One member of the expedition, Montana writer and lawyer Cornelius Hedges, later wrote a number of articles for a Helena, Montana-based newspaper, describing the things the expedition had witnessed. In discussions with other members of the party and in his writing for the newspaper, Hedges was a vocal supporter of setting aside the Yellowstone region as a National Park, an idea originally proposed by former acting Montana Territorial Governor Thomas Francis Meagher.

Encouragement
The Washburn party was clearly inspired by the journals kept by Charles W. Cook and David E. Folsom, as well as their personal accounts. Immediately after the Cook–Folsom–Peterson Expedition, Folsom went to work as a surveyor for Washburn.

Additionally, Langford had personal connections with Jay Cooke of the Northern Pacific Railroad well before their expedition. Cooke was interested in the potential of the Yellowstone region to attract railroad business. After the expedition, Cooke financed Langford's early 1871 speeches in Virginia City, Helena, New York, Philadelphia, and Washington, D.C. about the 1870 expedition on behalf of the Northern Pacific Railroad.

On January 19, 1871, one of those speeches in Washington, D.C. was attended by geologist Ferdinand Vandeveer Hayden, who became inspired to conduct his next geological survey in the Yellowstone region. The result was the Hayden Geological Survey of 1871.

 * August 29, 1870 – After several days of local exploration, the party leaves Tower Creek and ascends what they later name Mount Washburn 44.7975°N, -110.43333°W . From Mount Washburn the party can see south into the Grand Canyon of the Yellowstone, the Hayden Valley 44.64389°N, -110.45556°W and Yellowstone Lake.
 * August 30, 1870 – The party reached the Yellowstone Falls 44.71278°N, -110.49972°W and spent several days exploring the canyon and thermal features near the river.
