Formation of a glacial lake. Commonly, alpine lakes are formed from current or previous glacial activity (called glacial lakes) but could also be formed from other geological processes such as damming of water due to volcanic lava flows or debris, [6] [7] volcanic crater collapse, [8] or landslides.

The Great Lakes are the largest glacial lakes in the world. The prehistoric glacial Lake Agassiz once held more water than contained by all lakes in the world today. A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier.
Paleo-Indian presence along the shores of Jackson Lake is attested from 11,000 years ago in what is now Grand Teton National Park. [9] Jackson Hole valley climate at that time was colder and more alpine than the semi-arid climate found today, and the first humans were migratory hunter-gatherers spending summer months in Jackson Hole and wintering in the valleys west of the Teton Range.

The Alpine Lakes Wilderness is a large wilderness area spanning the Central Cascades of Washington state in the United States.The wilderness is located in parts of Wenatchee National Forest and Snoqualmie National Forest, and is approximately bounded by Interstate 90 and Snoqualmie Pass to the south and U.S. Route 2 and Stevens Pass to the north.
In these basins, if there was no outlet, glacial lakes (Gletscherrandseen or Zungenbeckenstauseen) were formed during the retreat of the glacier. There is a number of lakes of this type in the Salzkammergut, for example. Typical landforms within the Zungenbecken of the Alpine Foreland are drumlins, but there are rarely any tunnel valleys.

The Alpine Lakes Wilderness is a large wilderness area in the North Cascades mountain range, located in northern Washington state, the Northwestern United States. Lakes in the Alpine Lakes Wilderness are protected within the Wenatchee National Forest or Mount Baker-Snoqualmie National Forest.
