Ferdinand Vandiveer Hayden
1828 - 1887

Commander on Hayden's U. S. Geological Survey to Yellowstone and Colorado (1872-1873)

In 1871, Ferdinand Vandiveer Hayden's expedition was the first to explore Yellowstone. Hayden's popularization of the area contributed to Congress' decision to make it the first national park. Hayden returned with another expedition in 1872 to explore, document, and map the Yellowstone area in greater detail. The botany report for the 1872 expedition, written by John M. Coulter, the head botanist, was included in Hayden's Annual Report for the survey.

Commander on Hayden's U. S. Geological Survey to Colorado (1873)

In 1873, Hayden shifted his focus from Yellowstone to the Colorado Territory, directing a large expedition to explore, map, and survey the land. Hayden split the expedition into six parties, three of which surveyed portions of Colorado. The other three parties had specific tasks that would take them across the entirety of the territory. Although the expedition focused principally on geology and topography, biological collections were also made under Hayden's direction.

Other Accomplishments:

-Studied Natural History and Theology at Oberlin College (graduated 1850)
-Assigned his first Western exploration, a solo exploration of the White River Bad Lands in Nebraska (1853)
-Received his M.D. from Albany Medical College (1854)
-Served in Union army as a surgeon, becoming a medical inspector and eventually chief medical officer by the end of the Civil War (1862-1865)
-Appointed head of the Geological Survey of Nebraska (1867)
-Led various Geological Survey expeditions in Nebraska, Colorado, Wyoming, Montana, and Idaho (1867 - 1878)

Hayden's U. S. Geological Survey: Expedition to Colorado


In 1871 and 1872, Hayden led expeditions to the Yellowstone area in Wyoming, bringing back geological data, maps, and collections, as well as the photographs that helped popularize the natural beauty of Yellowstone. However, in 1873, the heavy expenses of shipping supplies to an area with no railroad, in addition to the threat of hostile American Indians, led Hayden to shift his focus to Colorado instead.

Hayden divided the Colorado territory into northern, middle, and southern regions, and assigned an expedition party to survey each area. In addition, there were three other parties whose duties covered the entirety of the Colorado territory. One party triangulated all of Colorado, and another transported supplies to the expedition members. The third party, led by photographer William H. Jackson, included an artist and several naturalists. This group was given the task of photographing, sketching, and gathering observations for the benefit of both scientists and the public.

The expedition focused on geology and topography, but the naturalists also made extensive collections of fossils, animals, and plants. John M. Coulter, who had accompanied Hayden’s expedition to Yellowstone in 1872, continued in his role as an expedition botanist in 1873. He was an assistant in the expedition, gathering plant specimens in the Park Range Mountains and nearby mountain streams. Coulter found several specimens near Clear Creek, a mountain stream tributary to the Arkansas River, including Britton’s skullcap (Scutellaria brittonii), which is a member of the mint family, and the Virginia strawberry Fragaria firma, now known as Fragaria virginiana, which he collected at over 8000 ft in elevation. Specimens found in the Park Range mountains include arctic brome (Bromus kalmii) found at Buffalo Peaks, and large mountain fleabane(Erigeron coulteri), a new species found at 10,000 feet in elevation at Weston’s Pass, to the north of Buffalo Peaks.

Instead of publishing his findings in the Annual Report of the expedition, as he had the year before, Coulter incorporated them into the Synopsis of the Flora of Colorado, a compilation of descriptions of plants found on various exploring expeditions. The Synopsis, which encompassed explorations ranging from Parry’s expedition in 1861 to Hayden’s most recent expedition, was written jointly by Coulter and Thomas C. Porter, a fellow botanist, and published in 1874.
