An American geologist; Hayden (1829-1887) is best remembered for his studies of the Northern Plains and Rocky Mountains. He began his career as a geologist working for James Hall and the Natural History Survey of New York. Hall convinced Hayden to work for early surveys of Nebraska Territory under Meek which led to his joining the Raynold’s exploration of the Yellowstone and Missouri Rivers region. The above offered work is Hayden’s account of the Raynolds Expedition and the survey of Yellowstone region in 1859-1860. The publication of the final report was delayed by Hayden’s work as a medical doctor in the Civil War. His report provides historical background on earlier research in the region. This is followed by detailed geologic information on the Yellowstone region as well as on the Black Hills, and includes observations on explorations in the Dakotas, Nebraska and Kansas. Chapters include an outline the physical geography and landforms of the Missouri drainage and its tributary streams, and describe rock formations and paleontology. Two chapters by J. S. Newberry describe the Cretaceous and Tertiary plants and invertebrate fossils of the region.
