Fed by the massive Columbia Icefield, the Athabasca River serves as a major geographic artery of Jasper National Park before flowing north towards the Arctic Ocean. At this specific bottleneck, the river forces its immense volume through a layer of hard quartzite, creating a dramatic display of erosive power rather than sheer height. This view captures the torrent as it surges into the narrow limestone gorge below, where decades of relentless water pressure have carved out a deep network of potholes and canyons in the rock.
