Lake Tekapo, New Zealand. A moraine-dammed lake, occurs when the terminal moraine has prevented some meltwater from leaving the valley. When a glacier retreats, there is a space left over between the retreating glacier and the piece that stayed intact which holds leftover debris . Meltwater from both glaciers seep into this space creating a ...
Tarn—a proglacial lake impounded by the terminal moraine of the retreating Schoolroom Glacier in Grand Teton National Park, Wyoming In geology, a proglacial lake is a lake formed either by the damming action of a moraine during the retreat of a melting glacier , a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic ...
Moraine-dammed lakes occur when glacial debris dam a stream (or snow runoff). Jackson Lake and Jenny Lake in Grand Teton National Park are examples of moraine-dammed lakes, though Jackson Lake is 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

The lake is fed by the Gurudongmar glacier and is a moraine-dammed lake. [3] It is located to the north of the Kanchendzonga range, in a high plateau area connected with the Tibetan Plateau. It provides one of the source streams, which joins the Tso Lhamo Lake and then form the source of the Teesta River. The lake remains completely frozen in ...
Verdi Lake in the Ruby Mountains of Nevada. The word is derived from the Old Norse word tjörn ("a small mountain lake without tributaries") meaning pond. In parts of Northern England – predominantly Cumberland and Westmorland (where there are 197), [2] but also areas of North Lancashire and North Yorkshire – 'tarn' is widely used as the name for small lakes or ponds, regardless of their ...
Rifflsee is a lake of Tyrol, Austria. [2] It is the largest lake in the Ötztal Alps. The mountain lake is located in the Kaunergrat west of the Pitztal and is a typical moraine reservoir. The lake fills an extensive valley, the glacier-turbid water looks greenish.
Below the glacier, water had been accumulating, dammed back by the moraine, and formed a lake some 250 m (820 ft) long and 150 m (492 ft) wide. Its depth was 15 to 20 m (49 to 66 ft), depending on the time of year. [2] The water in the lake mostly accumulated from rainfall and melting snow in its catchment area.
