GeologyGlacial Landforms
Quick Answer
A tarn is a small mountain lake formed in a cirque or other glacial basin. It usually occupies a hollow left behind by retreating ice.
The Full Story
Tarns are common in glaciated mountain regions and often sit in dramatic, steep-sided basins. They can be fed by snowmelt, rainfall, or small streams. Because they form in hollows carved by ice, they are useful clues for reconstructing past glacier extent. The word is especially common in British and alpine geography.
