A moraine is a type of glacial drift composed of unsorted material, known as till, that accumulates along the edges or terminal portions of a glacier. These deposits represent the bedrock of sediments scraped from the landscape and carried by the melting ice, forming distinct ridges or mounds. The material within a moraine is characteristically unstratified and highly heterogeneous, consisting of a mix of sizes ranging from fine clay and silt to large boulders and cobbles. The morphology of a moraine is dependent upon the specific flow dynamics and the retreat pattern of the ice body, serving as critical indicators of past glacial extent and magnitude.
