31) Crabioules Este, 32) Crabioules Central y 33) Crabioules Oeste

During the Little Ice Age, the glaciers of 31) Crabioules Este and 32) Central, together with the current Helero de 30) Maupás Oeste, formed a single unit covering 88 hectares. The entire system was the second largest glacier complex in the Perdiguero Massif and the sixth largest in the Pyrenees. The width of its head was 1,050 m and the maximum length of the tongue was 850 m. It is estimated that this system contained just over 20% of the ice in the entire Perdiguero massif.
The recent Helero de 31) Crabioules Este, located at the base of the wall of the Pico Oriental de Crabioules, maintained a considerable thickness until 2012. This Helero became extinct in 2023.
The 32) Crabioules Central glacier, located between the two peaks of Crabioules, the Eastern Peak at 3,116 m and the Western Peak at 3,106 m, was divided into four units that until recently were classified as ice fields. The upper section, located between 2,900 m and 2,950 m, is the result of a small ancient hanging glacier, which until its extinction shared many characteristics with the Upper Glacier of Monte Perdido. Its total extinction was recorded in 2023.
The Crabioules Oeste glacier developed during the Little Ice Age as an independent glacier covering an area of 11 ha, 210 m long and 520 m wide, extending along the base of the wall between Pointe Lacq (3,010 m) and Pico Lézat (3,107 m). It was recently split into two segments (33-1 and 33-2). Fragment No. 1, located inside the moraines, was classified in 2017 as a residual glacier. The West Crabioules glacier became completely extinct in 2019.
