YAKIMA, Wash. (AP) — The Yakama Nation has asked the federal government to halt construction of a natural gas pipeline across southwest Washington’s White Salmon River, saying the project will impair an archaeological site that is culturally significant to the tribe.

The line is being built to replace a small section of a 4,000-mile pipeline, stretching from Colorado to the Canadian border, which has been gradually unearthed since a dam was breached on the river last year.
