How do you tell a glacier lake?
How do you tell if a lake was formed from a glacier or not? Thanks.

ribbon lakes are long narrow lakes formed by the glacier carving out a groove in softer rock
the Finger Lakes in Upstate NY are a great example
I live near one as well, Lake Quinsigamond in Worcester MA
another lake formed by glacier is a tarn
it is simply a cirque, which is a hollow depression carved out by a glacier that is later filled with water. Just look for a lake or pond in exposed bedrock in the higher elevations of a mountainous region
and finally there are kettle ponds
they are formed by a chink of ice breaking off at the edge of a glacier and buried in a type of silty, sandy gravelly sediment called outwash. The ice melts leaving a depression, when it fills with water it becomes a kettle pond. if it remains dry it is called a keg
they are very much roundish in shapeSource(s): ..
