Numerous components, both natural and human, are present in the Park,
but the particular geological contents of the Breggia Gorge make it one
of the most important geo-topes in Switzerland and the first Swiss
geo-park.
Along this part of the river the natural section
created by the excavation of the water has brought to light a geology
profile that is almost continuous between the Jurassic and the Tertiary
periods (more than 80 million years).
Numerous pieces of
evidence of ancient seas are present in the rocks of the Gorge: layers
extremely rich in fossils, remains of underwater landslides, witness to
climatic changes in eras long before man appeared on Earth, and proof
of volcanic eruptions.
These remains have enabled the
evolution in very remote times of this part of the territory – the
Basin of Monte Generoso – to be reconstructed; then the Alps as we know
them did not exist and the rocks of which they are now composed were to
be found at a depth of thousands of metres in the earth’s crust or on
the bed of remote oceans.
The Park also has flora and fauna of value, among which many are protected species or are registered in Red Lists.
