The debris of boulders eroded and carried down by glaciers will eventually form moraines (mounds) where the front of the glacier melts and retreats, leaving the debris behind. Moraines can be high and wide enough to form a dam, behind which glacial melt water is trapped and lakes are formed.
The rock is called a glacial erratic when it is left behind by a glacier, and is of a completely different material composition than the rocks on which it was deposited.
The term "till" is the name given to unsorted rocky debris formed by melting glaciers.
Bottom and side?
still flows and carries debris to the end of the glacier
The unsorted rocky debris formed by a melting glacier is known as glacial till. This mixture of rock fragments of various sizes and shapes is deposited by the glacier as it retreats, with no specific order or arrangement. Glacial till can form different landforms, such as moraines or drumlins, depending on how it is deposited.
Glacier erosion is when the ground below the glacier is removed. Glacial deposition is when the debris (eroded ground) is left behind when a glacier melts and the face retreats.
Ridges of rock debris that form in front of a glacier are called terminal moraines at the point that the glacier stops moving ahead.

an accumulation of boulders, stones, or other debris carried and deposited by a glacier.
The retreating glacier leaves behind linear mounds of till (till being unsorted debris) and is known as moraine.

A short answer:Glacier debris, or more properly called glacial debris,would be made up of bits of rock that were deposited by a glacier after it had melted away.A longer answer:Glacial debris is produced by the action of glaciers. As you probably know, glaciers are massive sheets of ice that advance and recede depending on the amount of snow that they get and the climate in the area. Because they are made of ice, they are very strong and able to pick up rocks of all sizes, from large boulders to small specks of sand.As glaciers creep along the landscape, they often pick up these pieces of rock and transport them as the glacier advances. When the glacier melts, these pieces of rock are left behind as glacial debris.

Cape Cod is considered a terminal glacial moraine, meaning that it was created by debris left behind by a retreating glacier.
