Same at Hintertux glacier in Austria.
And Passo Stelvio, Italy at least on the poma track at the bottom. Schnalstal, Italy as well. Fonna in Norway....pretty much standard practice these days with glaciers, though Levi is the first place I have seen that is just covering snow piles that are not on or near a glacier. The blankets are interesting material- like felt.
