The quartzite

Description

The path passes along the edge of a big cutting, with boulders of quartzite. This is a metamorphic, siliceous rock which is very hard and formed by grains of quartz welded together. It originates from sand deposited 230 million years ago in the still-shallow waters of the nascent Alpine ocean, and brought here by the erosion of the surrounding topography.
