What is Alpine lake?
[[File:Denali-alpine-lakes-forest-Highsmith.jpeg|thumb|right|250px|Alpine lakes and forest, Denali National Park, [[Alaska]]]] '''Alpine lakes''' are [[lakes]] or [[reservoir]]s at high altitudes, usually over 5,000 feet (1524 metres) above [[sea level]], or above the [[tree line]]. Alpine lakes are usually clearer than lower lakes because the cold water reduces the speed and amount of [[algae]] and [[moss]] growing in the water. Often the lakes are surrounded by varieties of [[pine]] trees, [[aspen]]s, and other high altitude trees. [[Yellowstone Lake]] is an alpine lake, and so is [[Lake Baikal]]. {{geo-stub}} [[Category:Lakes]]
