Pink rock fragments

Accustomed to the usual colors of rocks around Gamone (gray, ochre, whitish and black), I was surprised to discover pink-hued fragments on the slopes, a few days ago, a hundred meters above the house.

Since these fragments were located in the middle of a flat pile of rocks covering a small zone of a few square meters, I first imagined that there might have been a fireplace at this spot. But that is almost certainly a false explanation. For the moment, therefore, this pleasant color remains a mystery.
