In British Columbia, a significant change is taking place at Mount Robson’s Berg Glacier, where it has retreated to the extent that it no longer reaches Berg Lake’s waters. Joseph Shea, a geography associate professor at the University of Northern British Columbia (UNBC), observed this transformation during a summer field project on the mountain when he captured a photo of the separated glacier.
Situated on Mount Robson’s north face, the Berg Glacier is a prominent feature near the Alberta border in central B.C. Previously, the glacier extended all the way to Berg Lake, shedding ice fragments into the lake. This process resulted in the formation of icebergs on the turquoise-colored lake, a sight that has attracted outdoor enthusiasts to the area, including the popular 23-kilometer Berg Lake Trail.
Recent monitoring efforts by B.C. Parks, in collaboration with UNBC researcher Brian Menounos, have highlighted significant changes in the Berg Lake glacier over the past six years. While Shea believes the glacier-lake separation may not impact the lake’s water levels, it signifies a shift in the natural landscape due to climate change.
Research led by Menounos has shown a 22% reduction in glacier surface area in Western Canada and Switzerland between 1985 and 2021, emphasizing the ongoing impact of glacier melt. The Berg Lake Trail also faced severe damage from climate-related events, notably during the province’s 2021 heatwave, resulting in evacuations and subsequent repair work.
Efforts are underway to establish real-time weather stations to gather crucial data for park management and hazard forecasting. B.C. Parks aims to utilize this information to enhance visitor safety and operational decisions within Mount Robson Provincial Park. The implementation of these weather stations is expected to provide valuable insights into glacier changes and contribute to mitigating environmental risks in the region.
