Staking the future: Natural Resources Canada teams will measure for snow density, depth of select glaciers in B.C., Alberta, the North.
The rapid retreat of the glaciers means more geo-hazards like increased flooding from melting ice and landslides. When they are gone in the future there will be more issues with creeks and rivers running low or drying up during late summer.
Using six-metre aluminum stakes drilled into the glacier, the scientists will measure for snow density and depth. Then they will return at the end of summer to record how much has melted at the Helm Glacier. They’ve also discovered a distinct lack of firn on his glaciers now. Firn is the multi-year-old snow that remains on the glacier during the melt.
“So once you start seeing these bits of rock coming through the glacier bedrock, it really means that that glacier is thin and that the melt will accelerate.”Policymakers need to understand the implications of these disappearing glaciers and what it will mean for B.C. when they are gone, said Ednie. It will also devastate B.C.’s mountain tourism industry as the province’s glaciers draw thousands of backcountry enthusiasts from around the world every year.
