VANCOUVER – The Sahaptin-speaking Indian people of the Columbia River Basin were hunters and gatherers who survived by virtue of a detailed, encyclopedic knowledge of their environment.

Eugene Hunn examines their ethnobiology and cultural ecology in his book, “Nch’I-Wána, the Big River: Mid-Columbia Indians and Their Land,” and in a lecture on the same topic to be held from 4:15 to 5:15 p.m., Tuesday, Nov. 7, in the Washington State University Vancouver Multimedia Classroom building, room 22.

Hunn is an ethnobiologist and professor of anthropology at University of Washington. He has also been involved in contract research for the U.S. National Park Service on subsistence issues in Alaska, and has testified in court regarding Pacific Northwest Native American resource and land rights.

The lecture is sponsored by the River Cities Anthropological Society and College of Liberal Arts at WSU Vancouver, and the Center for Columbia River History. Visit http://www.ccrh.org for more information.
