The Cascade Peaks are three summits in the Monte Perdido Range of the Pyrenees, culminating at 3,161 m (10,371 ft) on the eastern peak. The central peak, known as Brulle, and the western peak are 3,106 m (10,190 ft)[3] and 3,095 m (10,154 ft) high, respectively. The peaks are located on the 3,000 m French-Spanish borderline crest.

Toponymy

The central summit was named in honor of Henri Brulle.
