The lower surfaces of Ackerman Ridge are covered with young till; the thin till overlying glacial ice near the glacier margin thickens eastward with increasing |
distance from the glacier but the degree of weathering in the higher elevation till remains essentially the same; the till is unweathered and indicates the extent of |
late glacial retreat of the Scott Glacier |
