moraines
Moraine is the term used to describe ridges of rock debris left behind by a moving glacier. These ridges can vary in size and shape depending on the glacier's motion and the material it carries. They are a key feature in understanding the past movements of glaciers and their impact on the landscape.
The debris left behind by a melting glacier is called "moraine." Moraines consist of a mixture of soil, rocks, and sediment that the glacier has eroded and transported. They are typically found at the edges or terminus of the glacier, forming ridges or piles that mark the glacier's former extent.
The unsorted rocky debris left behind by a melting glacier is called glacial till. It is composed of a mixture of different sizes and types of rocks, deposited as the glacier retreats and melts, creating a diverse and unsorted collection of sediments.
Terminal moraine: a ridge of glacial debris deposited at the furthest advance of a glacier. Lateral moraine: debris deposited along the sides of a glacier. Medial moraine: a ridge of debris formed where two glaciers merge. Recessional moraine: ridges of debris left behind as a glacier retreats.
This type of hill formed when the glaciers melted is called a drumlin. This type of hill, which is oval and shaped like an inverted spoon, forms in lowland areas. The word drumlin is a Gaelic word.
Moraines are formed by the accumulation of unconsolidated rock debris, such as sand, gravel, and boulders, that have been transported and deposited by glaciers. The debris is carried along by the moving glacier and then left behind as the glacier retreats or melts, creating ridges or mounds of sediment.
Terminal moraines are ridges of glacial debris deposited at the furthest point reached by a glacier. They mark the end of a glacier's advance and can be seen as a line of debris and rocks left behind as the glacier melts and retreats. These moraines are called "terminal" because they are found at the glacier’s terminus.
Moraines are piles of rocks, soil, and debris left behind by glaciers. They can impact a landscape by creating landforms such as ridges, hills, and valleys. Moraines also play a role in shaping drainage patterns and influencing soil development in the area.
You may be referring to an "esker," a snake-like deposit of sediment left by a stream of running water underneath a glacier. At the edge of a glacier, a "moraine" also can form. A moraine is a pile of sediment and debris pushed by the glacier that forms alongside the glacier - a lateral moraine - or at the end of a glacier's run - a terminal moraine.

Such ridges are referred to as lateral moraines. As a glacier moves, it shears debris, such as rock and soil, on both sides, and this unsorted sediment forms ridges along the edges of the glacier.
Continental glaciers create a variety of landforms, including moraines, which are ridges of debris left behind as glaciers advance and retreat. They also form drumlins, which are streamlined hills shaped by glacial movement, and kettles, which are depressions that result from melting ice blocks. Additionally, continental glaciers can carve out large basins and fjords, reshaping the landscape significantly. These features reflect the dynamic processes of glacial erosion and deposition.
