Water Erosion at Sunwapta Falls

Water erosion at Sunwapta Falls is a powerful and ongoing natural process that has carved the deep, narrow gorge seen today. Fed by glacial melt from the Athabasca Glacier, the Sunwapta River carries immense volumes of sediment-rich water that grinds away at the surrounding limestone bedrock. Over thousands of years, this relentless force has sculpted steep canyon walls, undercut ledges, and potholes, creating the dramatic plunge and twisting channels that define the falls. In spring and early summer, when meltwater is at its peak, the erosive power intensifies, accelerating the reshaping of rock surfaces and deepening the chasm. This dynamic process is a vivid reminder of how flowing water, given time, can transform solid stone into intricate landscapes of raw beauty and geological significance.
