What began as a nod to conservation by a state government ended as a surprising discovery of Washington's 10,000-year human history [csmonitor.com].

Salmon conservation is not normally the business of a state's transportation agency, but in Washington, the State Department of Transportation tries to restore areas near large projects. Nine such projects are underway now, and one of them has caught the attention of the archaeological community.

Archeologists found stone tools buried deep under the river bank slated for a salmon conservation project. The discovery offers new evidence of earlier history of Washington's ancient humans than researchers knew existed. It also reveals the presence of greater cultural diversity than archaeologists had previously thought the area had, according to an article in the journal PaleoAmerica. This all came from "a region notoriously lacking" significant sites such as this.
