But now, Pastoruri has melted down to a third of a square mile—half its normal size after almost a dozen of the hottest years on record. This isn’t only a sad reminder of global climate change. It’s also a serious threat to the Cordillera Blanca economy as a mere 34,000 visitors came through last year compared to the heydays of the 1990s.
"There isn't much left of our great tourist attraction," said local guide Valerio Huerta, "Tourists now always leave totally disappointed."
