They kept the pile insulated over summer (it gets pretty warm in livigno) and had a lot left next season onto which they pointed a bunch of snow cannons for a good while, making a bigger pile.
obviously resorts (such as here mottolino) have to destroy the feature immediately so no crazy italian decides to end their life (or go into history books) on it.
With something intricate such as the castle its sad to see due to how many manhours went into that just for it to be pushed together by a cat.
