Perroud bridge

This bird climbs up branches much like a parrot would, using its crossbill. In terms of plumage, the male wears a brick red colour with brown wings and a brown tail. The female has olive plumage along her back and a yellow breast. This bird feeds primarily on conifer seeds. Food is also an important guide for this species behaviour; should food be lacking, it may suddenly leave its habitat for a more suitable environment. This mountain bird nests in the middle of winter, despite the harshness of the climate, to adapt to the period during which spruces start producing seeds.

Mont Fier seems to defy the rules of morphology set by the Jura relief. By its very definition, a mountain is comprised of an anticline (a fold that is convex upwards) and a synclinal valley (a fold that is convex downwards). However, on observing the limestone strata that make up Mont Fier’s cliff, there are signs of a very shallow syncline. This rocky headland, isolated between two depressions, is the only example of a perched syncline in the Jura.

As its name indicates, this place pays tribute to the significant event having occurred at the end of the Second World War. In addition to the historical background provided by the interpretive sign on the site, this belvedere offers a wide panorama over the Morez wind gap.

The old Perroud bridge, the waterfall and the ruins of the old mill are signs of just how much power the High-Jura needed to be able to grind, saw, and strike iron for example. 

This emblematic feline needs a vast territory with a large forest massif. It certainly needs space: the female’s territory is close to 200 km²n and that of a male is closer to 400 km²! A solitary animal, male and female lynx only meet during mating season, from February to April.
