Glacial Lakes and Ponds
Lakes and ponds may also be caused by glacial movement. Kettle lakes form when a retreating glacier leaves behind an underground or surface chunk of ice that later melts to form a depression containing water. Moraine-dammed lakes occur when a stream (or snow runoff) is dammed by glacial debris. Jackson Lake and Jenny Lake in Grand Teton National Park are examples of moraine-dammed lakes, although Jackson Lake is also enhanced by a man-made dam.
- Kettle lake: Depression, formed by a block of ice separated from the main glacier, in which the lake forms.
- Glacial Lake: A lake that formed between the front of a glacier and the last terminal moraine. Usually it is no longer in existence.

Famous quotes containing the words lakes and/or ponds:
“While the very inhabitants of New England were thus fabling about the country a hundred miles inland, which was a terra incognita to them,... Champlain, the first Governor of Canada,... had already gone to war against the Iroquois in their forest forts, and penetrated to the Great Lakes and wintered there, before a Pilgrim had heard of New England.”
—Henry David Thoreau (1817–1862)
“What if all ponds were shallow? Would it not react on the minds of men? I am thankful that this pond was made deep and pure for a symbol. While men believe in the infinite some ponds will be thought to be bottomless.”
—Henry David Thoreau (1817–1862)
