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:
“Though the words Canada East on the map stretch over many rivers and lakes and unexplored wildernesses, the actual Canada, which might be the colored portion of the map, is but a little clearing on the banks of the river, which one of those syllables would more than cover.”
—Henry David Thoreau (1817–1862)
“I have been accustomed to make excursions to the ponds within ten miles of Concord, but latterly I have extended my excursions to the seashore.”
—Henry David Thoreau (1817–1862)
