Environmental ripple effect of Bute Inlet landslide starting to unfold, scientists say

Environmental impacts from millions of tonnes of earth and water sluicing down a valley and spilling into the ocean are just beginning to be understood, say scientists studying a massive landslide in the Bute Inlet watershed. Climate change set the stage for the slide that occurred on the morning of Nov. 28, according to Brent Ward, a geologist at Simon Fraser University. A retreating glacier northeast of the head of Bute Inlet left a mountain slope above Elliot Creek unstable, said Ward, who is also co-director for SFU’s Centre for Natural Hazards Research. A section of the mountain normally secured by the glacier and located above an older slide came loose, plunging six to seven million cubic metres of rock and earth into a glacial lake at the head of the creek, Ward said.

  VICTORIA A massive glacial landslide that sent debris toward Bute Inlet on B.C.’s northwest coast has destroyed an already at-risk habitat, a local First Nation says. Homalco First Nation Chief Darren Blaney said the slide wiped out the coho salmon habitat in the inlet. “All the gravel that was there for the chum washed away, so it lost a lot of chum-spawning areas,” he said. “Certainly, it will affect our food security, with the chum stocks in decline. Southgate (River) was one of the more productive rivers in our territory. It’ll have an impact for sure.”

Massive landslide on B C coast imperils dwindling salmon stocks, says First Nations chief

Homalco First Nation Chief Darren Blaney is planning to visit the slide area about 120 kilometres north of Powell River and 220 kilometres northwest of Vancouver   by helicopter on Wednesday, but he told CBC News it s clear from photos that the slide was extremely destructive, pushing boulders down the valley and crushing dislodged trees.
