- •
Visual images and topography are used to map glacial debris aprons and plains units.
- •
An upper plains mantle unit resurfaced and modified debris aprons and older plains.
- •
Mantle is thick, was more widespread, and emplaced near end of debris apron flow.
- •
Possible buried ice from glacial retreat is preserved beneath mantle unit.
- •
End of glaciation marked by transition to deposition of dust-rich icy materials.
