Large crevice into which one can descend.
According to a legend, the pastor of Vals once had to go up to the village of Zerfreila (which was then flooded by the dam in 1957) to administer the last sacraments to a dying woman. However, the path had been buried by an avalanche and he couldn't continue to the village, but he couldn't go back to Vals either. He had already resigned himself to freezing to death here when it occurred to him that he must be near the "Warma Chracha". In fact, he was able to save himself up to this crevasse. He saw footprints in the snow, but not a soul far and wide, no matter how hard he shouted. Finally he gathered all his courage and climbed down into the crevasse. There he soon came across a wooden board and noticed with astonishment that he was standing by a coffin - the coffin of that dying woman from Zerfreila. Because there was no cemetery in Zerfreila at that time, the coffin should have been transported to Vals, but the pallbearers couldn't get through either and so they deposited the coffin in the warm Chrachä... the priest recognized this quickly and began immediately for them praying for the dead as if he had come in time.
The legend is much more extensive in the original :-)
