The Greatest Migration (2010) Trailer
Trailer for the documentary The Greatest Migration.
Snake River salmon swim more than 900 miles inland and climb almost 7,000 feet to reach their spawning grounds. These iconic fish travel farther and higher than any other salmon on Earth, but a gauntlet of dams blocks their great migration and is pushing these high-altitude salmon to extinction.
