A superpipe is a halfpipe that is about 64 feet wide and typically between 400 and 600 feet long, with walls approximately 22 feet high. The walls of the pipe are near vertical, with a smooth transition that allows riders to carry maximum speed.
The state fined Mammoth Mountain Ski Area LLC $26,810 for three violations related to the death, according to a July 2025 citation that is being reported here for the first time. The violations included not ensuring the patrollers were able to deploy avalanche airbags prior to the 25-year-old's death.
The ongoing storm is expected to add 13-16 cm at Banff Sunshine and around 4-5 cm at Lake Louise by Friday morning, with the deepest moisture focused on Alberta.
Avalanches kill about 100 people in Europe each year, with vast masses of ice, snow and rock regularly crashing down on hikers and skiers who have been caught unawares. The structure of the snow, angle of the slope and variation of the weather can dictate whether a gentle disturbance like a gust of wind or the glide of a snowboard can trigger a deadly shift in the mountain.
The parking lot pulsed with bass-heavy playlists and breakfast cocktails. Ski boots clicked alongside trail runners; bikes leaned against tailgates next to rock skis. Spring in the Northwest is less about conditions and more about community-and the stoke was high.
Kirkwood has had a pretty solid past few days, seeing 42 inches of snow through the past 7 days, 31 of which fell in the past 48 hours. As of April 13th, Kirkwood has 5 lifts spinning with 45 of 84 trails open to skiers and snowboarders.
Runaway snowboards were a cause of great concern in the early days of snowboarding as snowboards don't have breaks like skis. This concern was justified in many ways as proto snowboard bindings much less secure and reliable than modern systems using simple straps, rubber components, or basic buckles that could loosen or fail more easily during a crash.
The terrain park operates on different rules and guidelines than the rest of the ski resort. While the downhill skier always has the right of way on the rest of the mountain, skiers and snowboarders are responsible for clearing out of any landing zone as soon as they can. Hanging out in the landing zone or allowing your child to hang out in the landing zone, as we see in the video below, is absolutely unacceptable,
Cornice collapses can be incredibly dangerous, having the potential to crush people, pull them down mountains and potentially over rocky cliffs, and cause larger avalanches. Professional skier Josh Daiek doesn't seem to be impacted by cornices as much as a regular skier or snowboarder would be, though. This incredible line starts with a heart pounding moment as he looked over the edge.
On Monday, February 23, Pierre Denambride, the 51-year-old head of slope safety at Flaine in Haute-Savoie, France, was killed while working on the mountain. One day later, on Tuesday night, a 41-year-old resort worker died in a separate quad accident in Flims, Switzerland, part of the Flims Laax ski area. The back-to-back tragedies have drawn attention to the use of quad bikes-often fitted with tracks or crawler systems-by ski patrol, slope safety teams, and mountain operations staff across Europe and North America.
