Figure A5. Mount PriceLava flows emanating from Mount Price flowed towards the Cheakamus River valley (foreground). At the time of eruption, the valley was filled by glacial ice. The lava flow was stopped by the ice and ponded, eventually cooling. When the ice melted away, the ice-cooled lava-flow front formed a precipitous cliff; water ponded behind the lava dam, forming Garibaldi Lake (ice-covered lake to the left). The steep cliff failed in a series of landslides, the most recent of which occurred in 1855-1856. The location is referred to as 'The Barrier'. View to the east-southeast.
