Nel comprensorio sciistico Glacier 3000 di Les Diablerets (VD), una delle piste da sci più ripide del mondo (Black Wall) è stata chiusa. La causa? Una lunga crepa che taglia in due la pista.
La crepa sembra una voragine, ma in realtà è solo lo scollamento dello strato di neve dal terreno. Questo è dovuto - spiegano gli esperti - al recente aumento delle temperature e delle precipitazioni. Un autunno particolarmente mite, inoltre, non ha permesso al terreno di raffreddare adeguatamente: di conseguenza gli strati di neve scivolano facilmente sul terreno, producendo queste crepe.
Le fenditure lungo la pista
Il direttore del comprensorio Bernhard Tschannen ha dichiarato ai media romandi di non aver mai visto nulla di simile in 30 anni di esperienza. Per riaprire la pista si confida in un ritorno del freddo e di ulteriori nevicate.
