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.

A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment.
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 ...
They are formed when boulders become lodged on the glacial till floor by basal melting and can no longer be moved by the passing glacial ice and the resulting deformation of the till bed. [2] [3] A fluted moraine, also called a fluted moraine surface, is a glacial moraine whose surface exhibits parallel ridges, glacial flutes. They are ...
Kame: Irregularly shaped mound of sediments previously deposited by falling into an opening of glacial ice. 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 ...
A kame delta (or ice-contact delta, morainic delta [1]) is a glacial landform formed by a stream of melt water flowing through or around a glacier and depositing material, known as kame (stratified sequence of sediments) deposits.
A push moraine or pushed moraine is in geomorphology a moraine (a landform formed by glacial processes) that forms when the terminus advance of a lowland glacier pushes unstratified glacial sediment into a pile or linear ridge in front of it. A push moraine is identified by its ability to push sediment upwards from its original horizontal position.
