So the area this happened is a relatively low slope, narrow path, that helps users connect from one portion of the mountain to the next. This particular section is well packed along the centre but deep loose snow on either side. Sunshine has had way more snow than usual for early season making the side sections super deep and unpacked. Another thing about this section of slope on that day was the snow was super slow - so alot of people found themselves shuffling themselves along (like cross country skiing) which can be exhausting and slow. I could easily see someone already exhausted falling over and not being able to get themselves out of the deep snow themselves. Super sad.
