Archaeological Artifacts
Acer negundo was identified in 1959 as the material used in the oldest extant flutes from the Americas that were made of wood. These early artifacts, excavated by Earl H. Morris in 1931 in the Prayer Rock district of present-day Northeastern Arizona, have been dated to 620-670 CE.
The style of these flutes, now known as Anasazi flutes, uses an open tube and a splitting edge at one end. This design pre-dates the earliest known Native American Flute (which use a two-chambered design) by approximately 1,200 years.
