In a heart-stopping moment captured on video, a skier’s daring move unleashed a monstrous avalanche on Mount Lipallian in Alberta’s breathtaking Lake Louise Banff National Park. The jaw-dropping footage reveals the sheer power of nature as a massive slab of snow breaks free, roaring down the slope with unstoppable force after the skier’s fateful ski cut.
The incident, reported by skiing authority Snow Brains, unfolded on a southerly aspect of the mountain, where recent heavy snowfall—15 inches in just the past week—had drastically heightened avalanche risks. According to the report, the skier’s tactical ski cut struck a weak point in the shallow snowpack near a protruding rock, setting off a chain reaction that sent a wall of snow hurtling toward the cliff’s edge.



A ski cut, as explained by the National Avalanche Center, is a calculated, defensive maneuver used by experienced skiers to test unstable slopes. The goal is to trigger a controlled avalanche on the skier’s terms, ideally while maintaining speed and heading toward a safe zone. “If the slope does fracture, your momentum should carry you off the moving slab,” the Center notes. But as the chilling video shows, even the most calculated risks can spiral into chaos when nature takes over.
The footage serves as a stark reminder of the raw, unpredictable power of the mountains. As the snow cascades toward the cliff, it’s a heart-pounding glimpse of how quickly a single move can turn a thrilling adventure into a dance with disaster. In this case, the skier’s brush with danger underscores the razor-thin line between control and catastrophe in the wild, untamed backcountry.
