Mount Robson’s Berg Glacier in British Columbia is undergoing a significant transformation, with new findings indicating that the glacier has receded to the extent that it no longer reaches Berg Lake’s water. Joseph Shea, an associate professor of geography at the University of Northern British Columbia (UNBC), made this observation while leaving a field project on the mountain and capturing a photo this past summer. The glacier’s retreat from the lake, situated on the north face of Mount Robson, the highest peak in the Canadian Rockies near the Alberta border in central B.C., is considered a symbolic and visible indication of climate change.
Previously, the Berg Glacier extended to Berg Lake, where ice fragments from its lower edge would break off and fall into the lake, contributing to the formation of icebergs that could be seen floating on the turquoise-colored lake, even during the summer months. The Berg Lake area, encompassing the popular 23-kilometre Berg Lake Trail, attracts numerous outdoor enthusiasts, with camping spots booking out for the entire summer within hours of reservations opening in the spring.
B.C. Parks has been collaborating with UNBC researcher Brian Menounos over the past six years to monitor the Berg Lake glacier, noting significant changes in recent times. Menounos’ research revealed a concerning trend of glacier surface area loss in Western Canada and Switzerland, with approximately 22% lost between 1985 and 2021. The Berg Lake Trail suffered severe damage from climate-related events, such as flooding caused by rapid snow and ice melting during the record-breaking heatwave in 2021.
Efforts are underway to mitigate the impact of climate change on the region, with ongoing research and infrastructure development. Real-time weather stations are being set up by B.C. Parks to collect essential data on weather conditions, snowpack, and other environmental factors. This information will aid in park management, wildfire forecasting, avalanche prediction, and overall safety measures for visitors. Mount Robson Provincial Park staff will utilize the data from these stations to make informed decisions regarding park operations and respond proactively to potential hazards for visitors.
