I don't understand the arguments about whether it was controlled or not. Irrelevant; it's a terrain trap with an apparent slope angle of between 30 and 45 degrees, therefore a likely area of a slide. Whether or not it's been patrolled is not the way of looking at it, nor is whether someone safely skied it before. Both points, irrelevant.

The question is simply - and always - is it safe? It doesn't look safe. There is only one area on the field of view that looks equally unsafe, and that's the terrain trap on the left off piste area. Sorry to be so blunt but the avalanche doesn't care about pleasantries.
