More specifically, this type of moraine is likely a lateral moraine. Lateral moraines form along the sides of a glacier, where rock debris accumulates as the glacier moves.
Here are some other types of moraines:
* Terminal moraine: A ridge of debris marking the furthest advance of a glacier.
* Recessional moraine: A ridge of debris marking a temporary halt in the retreat of a glacier.
* Ground moraine: A sheet of till deposited beneath a glacier.
* Medial moraine: A ridge of debris formed when two glaciers merge.
