Barrosa cirque, Glacial landform in Huesca Province, Spain
Barrosa cirque is a bowl-shaped glacial formation in the Pyrenees featuring steep rock walls that rise sharply on three sides. The horseshoe-like depression displays the classic structure created when moving ice carved deep into the mountainside.
The cirque took shape during the ice ages of the Pleistocene epoch when large glaciers sculptured the mountainous landscape. Repeated cycles of glacial advance and retreat over thousands of years created the formation we see today.
The cirque draws numerous geologists and researchers who study its geological formations to understand the patterns of glacial movements in the Pyrenees.
Visitors follow marked hiking trails that lead toward the Cabane de Barrosa and continue to the cirque. The best time to hike is from late spring through early autumn when snow has melted and the paths are safe to walk.
The cirque is notable for the scattered angular granite boulders that lie around its perimeter. These blocks were carried and deposited by glacial ice, showing how far and with what power the ice once extended.
