Canada: workers race to free millions of salmon trapped after huge landslide

• Rockslide on banks of Fraser River created impassable barrier
• Heavy machinery and helicopters used to help gather fish

Helicopters, heavy machinery and nearly 200 workers are frantically working to free millions of salmon trapped by a landslide in western Canada.

Government crews in the area have worked relentlessly along the banks of the Fraser River to clear debris after a rockslide, discovered in a late June, created an impassable 5m-high waterfall.
