Mount Robson’s Berg Glacier in British Columbia is undergoing significant changes, with researchers discovering that the glacier’s retreat has led to a noticeable separation from Berg Lake. Joseph Shea, a geography associate professor at the University of Northern British Columbia (UNBC), observed this separation during a summer field project on the mountain. This shift is considered a symbolic change by Shea, who highlighted the evident signs of glacier transformation in the region.
Located on the north face of Mount Robson, the highest peak in the Canadian Rockies near the Alberta border, the Berg Glacier used to extend all the way to Berg Lake. Ice breaking off from the glacier’s lower edge would fall into the lake, creating icebergs that floated on the turquoise waters, a sight popular among visitors. The Berg Lake Trail, spanning 23 kilometers, is a favorite destination for outdoor enthusiasts, with camping spots often selling out quickly each summer.
B.C. Parks, in collaboration with UNBC researcher Brian Menounos, has been monitoring the Berg Lake glacier over the past six years, noting significant changes. Despite the glacier no longer directly feeding icebergs into Berg Lake due to the retreat, visitors can still expect a stunning experience at Mount Robson. The separation serves as a visual representation of the impact of climate change.
Research by Menounos and the Ministry of Water, Land, and Resource Stewardship revealed a loss of approximately 22% of glacier surface area in Western Canada and Switzerland between 1985 and 2021. The Berg Lake Trail suffered damage during a record-breaking heatwave in 2021, causing high water levels that led to the evacuation of hikers from the park.
Efforts are underway to mitigate the effects of climate change on the region, with Shea working on setting up real-time weather stations to monitor snowpack, temperature, humidity, and precipitation. This data will aid park management systems in making informed decisions and providing advance warning of hazardous conditions. B.C. Parks plans to make real-time weather data available by late 2026, enhancing safety and operational decisions at Mount Robson Provincial Park.
