A tarn is a small mountain lake formed in a cirque, which is a bowl-shaped depression carved out by glacial erosion. When the glacier retreats, it leaves behind this circular depression that fills with water, creating a tarn. These are commonly found in mountainous regions that were previously glaciated.
