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 Yellowstone

(1872)

Plant collecting in the Geyser Basins of Yellowstone can yield some unusual specimens. John M. Coulter—botanist on Ferdinand Hayden’s second expedition into the new national park—noted in his expedition report that the heat from the geysers and hot springs caused some plants to grow much larger than usual. Coulter even found that several species of the Gentianella genus were unexpectedly darker in coloration, describing that they had “perfectly black stems and veins, leaves unusually dark, and petals with the black appearance common to dried specimens.”

Despite the plethora of interesting plants, the main mission of the 1872 expedition was to document the geology and topography of the Yellowstone area, particularly the Snake and Missouri Rivers. Nevertheless, Coulter and Assistant Naturalist Walter Platt collected numerous fossil, animal, and plant specimens. Coulter also made observations on the differences in the plant life in the various environments they encountered, from the desert to the Geyser Basins.

The landscape of the first leg of their journey—in the region between Ogden and the Teton Basin—was dominated by sage brush and other desert plants such as the sego lily (Calochortus nuttallii). Due to the low diversity of species, Coulter described the region as a “dry, sandy” desert with an “unpleasant sameness” to the landscape. He also noted the “entire absence of trees” on the plains, except for the occasional “stunted growth” near a large stream. Near the Great Salt Lake, however, the plant life was a little different: the alkaline soil was unsuitable for many species, so Chenopodiaceae were very common.

Sub-alpine and alpine plants, including the Ponderosa pine (Pinus ponderosa), dominated the region between the Teton mountain range and the mountains near Yellowstone. At around 11,000 feet in elevation the tree life abruptly ceased to exist, leaving a distinct timber line that Coulter believed marked the lowest temperature that the trees could endure. However, plant life continued above the timber line. When exploring Mount Hayden, Coulter collected plants at elevations up to within 300 feet of the summit, at about 13,800 feet.

Coulter noted that, “[f]erns are almost unrepresented [in the Yellowstone area], owing to the great dryness of the climate.” However, some fern species, including the winter grapefern Botrychium lunarioides, could be found in the Geyser Basin or near water sources in the Teton mountains. Mosses and lichens were common on the Teton mountain range, and dominated the landscape at elevations too high for forest plants.

Three of the approximately 1,200 plant specimens collected were species that had not been previously collected in North America. The “Longhorn Steer-Head” Dicentra uniflora—a member of the bleeding-heart genus—was collected on the summit of a mountain at 10,000 feet in elevation. The other two new species, Peziza vulcanalis and Sphaeria coulteri (named after Coulter), were both fungi. Coulter himself believed that western explorations such as Hayden’s Survey contributed valuable information to the field of botany. As he said in his Report to Hayden, “[t]he study of western flora is an immense field open now to all lovers of botany, and many rich harvests are waiting to be reaped by the industrious collector.”
