Duwamish Number 1 Site
The Duwamish Number 1 Site, also known as 45KI23, is an archaeological site on the Duwamish River in Seattle, Washington discovered by David Munsell, an archaeologist employed by the U.S. Army Corps of Engineers, in November 1975. The site was excavated by archaeologists in 1978, and again in 1986. According to an archaeologic report released in 1981, the site was a shell midden and village between 670 and 1700 CE, comprising four separate eras of occupation. The researchers also found remains of ducks, as well as of mammals such as deer and elk. The site is owned by the Port of Seattle. See also
