In 1929, 19-year-old James Ridgely Whiteman discovered prehistoric stone tools and mammoth bones at Blackwater Draw near Clovis, New Mexico. He reported his findings to the Smithsonian Institution, but formal scientific investigation did not begin until 1932 when archaeologist Edgar B. Howard from the University of Pennsylvania Museum conducted excavations at the site. These excavations confirmed the association of distinctive fluted projectile points with extinct Ice Age mammals, establishing what became known as the Clovis culture, which dramatically changed understanding of when humans first inhabited North America.
