Five grey whales have now washed ashore dead in B.C. in the last 2 months. Three of them have been found on the shores of Haida Gwaii. Proving to be a significant issue along the west coast, more than 60 grey whales have been found beached and dead along the West Coast between California and Alaska this year. Marine mammal experts are on Haida Gwaii working to determine the whales' causes of death.
