Bear Glacier Park

• History: Ice once filled all of Bear River Pass. In the 1940s, Bear Glacier began to retreat and Strohn Lake formed in the exposed basin. Acting as an ice dam, the glacier prevented the lake from draining down the Bear River Valley. If enough water collects behind an ice dam, a glacier may begin to float. Water flowing under the ice quickly creates a large tunnel. The lake empties, the ice dam resettles, and water again begins to collect until another flood is triggered. Five times between 1958 and 1962 Strohn Lake emptied underneath its ice dam in a catastrophic tumult of muddy water, rock and ice. This type of flood is known by the Icelandic term “jokulhlaup.” In 1967, Bear Glacier melted away from the valley wall and Strohn Lake was no longer dammed. The threat of sudden destructive icy floods in the Bear River Valley disappeared with the glacier’s retreat. Bear Glacier Park was designated as a Class A Provincial Park in 1998.
• Conservation: Bear Glacier Park lies within the Nass Wildlife area and protects part of a large glacier and a glacial lake.

BC Parks honours Indigenous Peoples’ connection to the land and respects the importance of their diverse teachings, traditions, and practices within these territories. This park webpage may not adequately represent the full history of this park and the connection of Indigenous Peoples to this land. We are working in partnership with Indigenous Peoples to update our websites so that they better reflect the history and cultures of these special places.
