Definition
A tarn is a small mountain lake or pool, often formed in a cirque excavated by a glacier. Think of it as a jewel nestled high in the mountains. ๐๏ธ Unlike larger lakes, tarns are typically small and deep, surrounded by steep slopes. They often have a distinctive blue or green color due to the glacial sediments. Tarns are beautiful, serene, and a reminder of the power of glaciers. These are places of great beauty, but sometimes difficult to reach.
