Glacial lakes can be green in colour. This is the result of ground up minerals (rock flour) supporting a large population of algae. [1]
A retreating glacier often leaves sections of ice behind, in hollows between drumlins or hills. As the ice age ends these will melt to create lakes. These lakes are often found surrounded by drumlins, along with other evidence of the glacier, such as moraines, eskers and erosional features such striations and chatter marks.

Avalanche Lake is located in a cirque on the west side of the continental divide.
For those of you lucky enough to get to Avalanche Lake on a warm day soon after the trail opens in May, you will be treated to the sights and sounds of many avalanches, which is quite a sight if you have never seen one up close before.
The outlet of the lake, which is where the trail ends, receives a fair amount of fishing pressure by park standards.
While all countries with glaciers are susceptible to this problem, central Asia, the Andes regions of South America and those countries in Europe that have glaciers in the Alps, have been identified as the regions at greatest risk [1].
The lake is growing larger every year due to the melting and retreat of the Trakarding Glacier, and has become the largest and most dangerous glacierlake in Nepal, with approximately 90 to 100 million m³ (117 to 130 million yd³) of water stored [2].
A Jökulhlaup is a glacier outburst flood, principally from an ice-dammed lake.
