The snow-free debris hills around the lagoon are lateral and terminal moraines of a valley glacier in Manang, Nepal.. A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet.

The Oak Ridges Moraine is an ecologically important geological landform in the Mixedwood Plains of south-central Ontario, Canada. The moraine covers a geographic area of 1,900 square kilometres (730 sq mi) between Caledon and Rice Lake , near Peterborough .
Moraine: Built up mound of glacial till along a spot on the glacier. Feature can be terminal (at the end of a glacier, showing how far the glacier extended), lateral (along the sides of a glacier), or medial (formed by the merger of lateral moraines from contributory glaciers). Types: Pulju, Rogen, Sevetti, terminal, Veiki
Multiple erratics on the terminal moraine of the Okanogan Lobe. The Cascade Mountains are in the background.. The term "erratic" is commonly used to refer to erratic blocks, which geologist Archibald Geikie describes as: "large masses of rock, often as big as a house, that have been transported by glacier ice, and have been lodged in a prominent position in the glacier valleys or have been ...
Athabasca Glacier, Jasper National Park, Alberta.. A comprehensive list of glaciers in Canada began with glacial surveys by the Water Survey of Canada (WSC) from 1945 to 1980, [1] including an inventory begun for the International Geophysical Year (1957–58) and contributions to the World Glacier Inventory (WGI, now part of the World Glacier Monitoring Service) for the International ...
The forested ridges in the lake are 'Rogen moraines' of which this is the type location. A Rogen moraine, also called ribbed moraine, is a subglacially (i.e. under a glacier or ice sheet) formed type of moraine landform, [1] that mainly occurs in Fennoscandia, [1] Scotland, [2] Ireland [3] and Canada. [1] [4] It is one of the three main types ...
Lateral moraines are formed on the sides of the glacier. Medial moraines are formed when a glacier meets its tributary glacier and merge, and the lateral moraines of each coalesce to form a moraine in the middle of the combined glacier. Less apparent are ground moraines, also called glacial drift, which often blankets the surface underneath the ...
