The Ski Patrol has been all over the steep terrain on the North Side and in the Steep Gullies. They try and beat up the snow, breaking all the propagation pathways. This prevents larger slabs from forming and weaker lower layers from collapsing. They use explosives, they ski cut, they side step down the slopes. Not only does this reduce the chance of avalanches, it makes the skiing a whole lot better with subsequent snowfall.
This is text book ski cutting on the Pali Lift line.
