Arcouzan Glacier, Cirque glacier at Mont Valier, France
Arcouzan Glacier sits on the northeastern slope of Mont Valier in the Pyrenees, located between 2,320 and 2,520 meters in elevation. The terrain displays the typical features of a cirque glacier, with steep rock walls enclosing the icy mass.
Scientists first recorded this glacier in 1808, confirming it had existed since at least 1802. These early observations placed it among the known ice features of the Pyrenees during the early 1800s.
The name Arcouzan comes from a journalist who labeled it in 1940, though local residents have long debated whether the name truly reflects the glacier's geography. Visitors can spot informational signs along the access routes that explain the naming controversy and its connection to local water features.
Reaching it requires high-altitude fitness and proper mountain gear due to steep, rocky terrain. Visitors should prepare for variable weather conditions typical of high-altitude environments.
While most Pyrenean glaciers shrank during the 2010s, this one actually expanded, showing unexpected behavior among its peers. This unusual pattern makes it a notable example of how glaciers respond differently to regional climate changes.
