What is the summer sun doing? How is this good and bad?

The summer sun was melting the snow and uncovering some bodies that had been previously unattainable. Unfortunately for Fito, the body he found belonged to his deceased cousin, Daniel, and he was reluctant to use it. It was placed on reserve along with that of Liliana Methol, who had died in the avalanche. Their bodies were only to be consumed when all of the others were gone.
