Annotation Of Expeditions And Individuals Recording Natural History Notes
Hayden Survey, 1854-1855:
Hayden was an American born geologist and naturalist who contributed greatly to the natural history explorations of the western United States. He led or accompanied six expeditions that penetrated Montana between 1854 and 1877. After working the summer of 1853 for an eastern college geology professor along the White River in South Dakota, he led his first expedition to Montana in 1854-1855. On this expedition, he explored the upper Missouri and Yellowstone Rivers (Figure 14). Hayden funded this expedition himself and primarily collected fossils. Although Hayden's main interest was in geology, he recorded excellent natural history notes and made valuable plant and animal collections.
