There is a striking contrast between the coastline and the archipelago's limestone islands, first the coastline is cover with huge peat bugs and swamps where rise here and there dark hills dress with deep green spruces.
These rocky outcrops are a part of the Canadian Shield which exposes the most oldest rocks of the earth, magma cooled more than 3 billion years ago.
Islands are much younger, the grey limestone which composes them dates from the beginning of life 450 million years ago.
Mainly constituted by organic matter deposited at the bottom of the water, these islands made little by little surface since the last glaciation, from 20 000 years to 2 500 years ago.
The rivers made by the melting glaciers who recovered the shore sculptured these surprising structures (sometimes called tea pots) which contain numerous fossils.
We visited the eastern part of the archipelago and on the three visited islands, two showed monoliths: the island of Wreck of which we have made the round trip by boat and the Nue island on which we spent several hours, the following photos result all of Nue island visit :
