Why do we protect artifacts?

The stretch of the Columbia River that makes up Grant PUD’s project territory is rich with artifacts from the Wanapum and other Native American groups that traveled along the river and made it their home. The shoreline’s prehistoric and historic archaeological sites, isolated artifacts, archaeological districts, structures, engineering features, landscapes and traditional cultural properties are all protected by state and federal laws. Grant PUD and the Wanapum take the protection of these sites and artifacts very seriously.


In Washington, archaeological sites and Native American graves are protected from known disturbance by a variety of state and federal laws. Federal law applies to all federal and Native American lands and Washington State law applies to all other lands. The following is a list of existing laws regulating archaeological sites:
