Description

Definition

An extensive, low-relief area of till, that has an uneven or undulating surface and is commonly bounded on the distal end by a recessional or end moraine. Ground moraines usually consist of poorly sorted rock and mineral debris (till), which has been dragged along, in, on, or beneath a glacier, and then deposited by basal lodgment and release from downwasting stagnant ice by ablation.
