Nature is pretty so are Rocks🪨

These are scattered boulders on a massive metamorphic rock called porphyritic gneiss. (A metamorphosed igneous rock)

We’re in Ariège, again marvelling at how varied, wooded & wonderful a place it is. Eg today = waterfall through gneiss boulders in conifers at 1000m, family oakwood walk at 500m & limestone caving with the kids over lunch.

Keen for snowy hills & sunny rock here in future years.

Freshly built One Rock Dam today. The stone is granite, gneiss, and schist. Plenty of it. This one is part of a series being built right now.
