Athabasca Falls is a segmented horsetail waterfall on the upper Athabasca River in Jasper National Park, Alberta, Canada. The falls lie approximately 30 kilometres (19 mi) south of the town of Jasper and just west of the Icefields Parkway (Highway 93).
Physical characteristics
- Total height: 24 m (79 ft)
- Number of drops: 2 (longest drop 20 m / 66 ft)
- Total width: 46 m (151 ft); average width 30 m (98 ft)
- Run (horizontal distance): 15 m (49 ft)
- Average discharge: 113 m³ s⁻¹ (≈ 4 000 cu ft s⁻¹)
The waterfall is classified as a Class 5 waterfall, notable more for the volume of water than for its height. The river plunges over a hard quartzite cap and then erodes the underlying softer limestone, creating a short gorge with numerous potholes and gulleys.
Access and visitor facilities
A parking area off Highway 93A provides direct access to a network of short walking trails and several viewing platforms that allow safe observation and photography of the falls. A historic vehicular bridge and a nearby pedestrian bridge cross the river at the falls. The site is a common launch point for white‑water rafting trips that travel downstream on the Athabasca River toward Jasper.
Geological context
The falls are the result of glacial meltwater from the Columbia Icefield feeding the Athabasca River. Over geological time, the river’s powerful flow has cut through the quartzite‑limestone sequence, shaping the present‑day gorge and associated erosional features.
Conservation
As part of Jasper National Park, Athabasca Falls is managed by Parks Canada, which maintains the viewing infrastructure and monitors the natural environment to preserve the waterfall’s ecological and aesthetic values.
