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.
The York and Escrick glacial moraines swing north and merge north of Wetherby to cover the magnesian limestone with glacial deposits. In the Bedale area and northwards, these deposits are so extensive as to mask the limestone topography. South of Wetherby there is only a thin layer of glacial deposits overlying the limestone.
Moraines are commonly found near the extremities of a glacier, the bounds between two glacial bodies, or underneath a glacial body. Moraines may be used to mark the extent of a glaciated region and the successive patterns of advance and retreat during glaciation. [ 3 ]

Franz Josef Glacier in New Zealand Features of a glacial landscape. Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. [1] The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. [2]
Fluted moraines mainly developed in till surfaces on land, but some have been found in shallow glacimarine settings. [1] [2] [3] Finally, in glaciology, fluting is used in older publications for smooth, deep, gutterlike channels or furrows cut by glaciers into the stoss side of a rocky hill obstructing its advance. Fluting is larger than ...
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 ...
