Holbrook in Navajo County, Arizona — The American Mountains (Southwest)
Pioneers of Paleontology
Interest in the areas fossils goes back to 1853, when a U.S. Army expedition discovered the Black Forest in what would become the parks northern section. Later, at the request of General William Tecumseh Sherman, two petrified logs from that area were acquired for the Smithsonian Institution.
Conservationist John Muir collected fossils and named some of the parks “forests” in the early 1900s, when he was living in nearby Adamana.
Annie Alexander and a companion discovered some of the first fossil reptiles and amphibians in 1921. They brought their findings to the attention of Charles L. Camp, who went on to spend nearly a decade studying the fossil vertebrates of the area.
These scientists are just some of the paleontological pioneers who laid the foundation of current studies into the parks treasure trove of fossils.
