These halls showcase artifacts such as cooking utensils, clothing, weapons, and jewelry from traditional Native American cultures in the East and in the Plains. The Hall of Eastern Woodlands Indians focuses on the traditional cultures of the Mohegan, Ojibwa, Cree, and other Native American peoples living in the Eastern Woodlands of North America. In addition to artifacts, this hall features models of Eastern Woodlands lodgings, from the wigwam of the Ojibwa to the longhouse of the Iroquois. The Hall of Plains Indians focuses on the cultures of the mid-19th-century Blackfeet, Hidatsa, Dakota (Sioux), and other peoples of the North American Plains, and is also home to one of the Museum's greatest treasures, the Folsom Point. This flint arrowhead, found near Folsom, New Mexico, in 1926, provides irrefutable evidence that there were humans in the Americas as early as the last ice age.
