British Columbia geoscientists are returning to the scene of a massive landslide on the Fraser River to map its effects and assess the risk of future slides on salmon.
The landslide in November 2018 created a five-metre waterfall on the river north of Lillooet, and made it nearly impossible for migrating salmon to reach their spawning grounds.
Jeremy Venditti, principal investigator on the project, said his team of scientists will map the topography in the area using a laser to identify between 20 and 100 possible slide sites along the river.
“We’re looking for sites that might be sort of an imminent threat, or where an imminent slide may happen, and then we’ll also be identifying locations where they could happen,” he said in an interview Thursday.
