The Barrier is a lava dam retaining the Garibaldi Lake system in southwestern British Columbia, Canada. It is over 300 m (980 ft) thick and about 2.4 km (1.5 mi) long where it impounds the lake.[1]
The area below and adjacent to The Barrier is considered hazardous due to the unstable lava formation.
