[edit]DescriptionCOLLAPSED - SPROFONDATA.jpg |
Italiano: Uno speleologo si sta calando per 25 metri da un grande varco del soffitto in questa stupefacente sala di una grotta illuminata da luce totalmente naturale. Questi fasci di luce si muovono durante il giorno, seguendo il sole, e la grotta cambia continuamente aspetto. Stavamo esplorando questa grotta vicino a Lucca (Toscana, Italia), cercando di rilevare tutto lo spazio possibile.
