An unusual series of suspended glacial cirques
Circhi delle Vette, isolated and solitary nival basins, represent a unique series of suspended glacial cirques, shaped by small cirque glaciers during the latest glaciation and, subsequently, by snow and karst phenomena (karst-nival basins). In some cases, the bottom of the cirques (Busa delle Vette, Busa di Pietena) has been overexcavated by the karst corrosion (glacial-karst basins) and often minutely sculpted by karst phenomena (glacial-karst environment).
