Completion of the land-back conservation deal along the lower Klamath River is being called the largest in California history.

The Yurok Tribe, California's largest federally recognized tribal nation, was given 73 square miles of land -- or 47,097 acres -- along the eastern side of the lower Klamath River on Thursday. The land exchange is being called the argest single “land back” deal in California history.

The tribe says they will initiate restoration projects on the 17,000 acres taken from them during the gold rush.
