"Every year I feel a kind of sadness when these days approach," sighs hiker Biel Grau (Lliçà d'Amunt, 1948). Exactly 25 years ago, he lost two close friends buried by an avalanche while descending from the summit of Costabona, "a mountain of cows" at 2,465 meters in the Ripollès region. He survived for two days buried under the snow. It was the painful epilogue to the tragedy that had taken place three weeks earlier. Nine dead in the Balandrau area.
