綠樹冰湖映

山峰夕照明

悠悠生戀意

從此不歸城

Alpine lakes are classified as lakes or reservoirs at high altitudes, usually starting around 5,000 feet (1,524 m) in elevation above sea level or above the tree line.

Alpine lakes are usually clearer than lakes at lower elevations due to the colder water which decreases the speed and amount of algae and moss growth in the water. Often these lakes are surrounded by varieties of pine trees, aspens, and other high altitude trees.
