The Barrier, Volcanic cliff in British Columbia, Canada.
The Barrier is a volcanic cliff formation in the Garibaldi area that spans across the valley like a natural dam. It holds back the water body behind it and defines the landscape of this mountain region.
This cliff formed roughly 12,000 to 15,000 years ago when lava flows met glacial ice, creating this massive geological structure. The interaction between volcanic activity and ice shaped the valley that exists today.
The provincial government monitors this geological formation closely, as its stability directly affects the safety and development plans of surrounding communities.
Visitors can view this formation from marked hiking trails and should avoid areas directly beneath the cliff face. The best time to explore is during warmer months when trails are accessible and conditions are favorable.
This natural dam holds back Garibaldi Lake, which reaches depths of 258 meters and covers an area of nearly 10 square kilometers.
