Today more than 60% of French glaciers are protected by being in a national park or nature reserve.
For the glacier, it is required to equip yourself with crampons, which is not the case for a rock race where it will be counterproductive for the hiker.
These changes in terrain have direct consequences on the practice of mountain hiking and the adaptation of routes.
The first modifications have already been made to the maps of the National Geographic Institute, IGN.
The agents of the National Geographic Institute themselves report the changes which also concern the appearance of certain watercourses.
In the Alps we know that all the ice will have disappeared by the end of the century.
The National Geographic Institute does not go so far as to remove the names of glaciers from its maps.
In the Pyrenees, only 10% of the glaciers present a century ago remain.
In the Alps for example, 70% of the ice has already melted, according to Météo France.
