Deep horseshoe-shaped basins formed as a result of glacial erosion, cirques are the ‘headwaters’ of a glacier Cirque formation is initiated when the climate is cool enough in the area to allow snow to remain year-round in small hollows above the snowline Meltwater from these small snowfields seeps into cracks in the surrounding rocks during times of partial melt, then re-freezes as the temperature falls in the winter, fracturing and loosening the bedrock Subsequent meltwater and ice-flow remove the loose debris and the process begins anew Over a period of thousands of years, the cycle of fracturing, erosion, and removal transform the small hollows into spectacular cirques As the glacier retreats and, eventually, completely disappears a lake will often remain in the cirque Such lakes are known as tarn lakes . . a deep recess in a mountain; it resembles an amphitheater with steep walls .8.
