264 PROCESS AND FORM

Table 10.3—Cont’d
Orientation with Landform Description
ice flow

Gentle hill A mound of till resting on a isolated block of bedrock
Hummocky ground (See hummocky moraine above)
moraine
Cover moraine A thin and patchy layer of till that reveals the bedrock topography in part
(a blanket ) or in full (a veneer)

Ice marginal during deposition
Transverse End moraines: Any moraine formed at a glacier snout or margin
Terminal moraine An arcuate end moraine forming around the lobe of a glacier at its peak
extent
Recessional moraine An end moraine marking a time of temporary halt to glacial retreat and not
currently abutting a glacier
Push moraine An end moraine formed by sediment being bulldozed by a glacier snout.
Some push moraines show annual cycles of formation and comprise a set
of small, closely spaced ridges
Non-orientated Hummocky moraine (See hummocky moraine above)
Rockfall, slump, debris Discrete landforms produce by each type of mass movement
flow

Plate 10.10 Line of angular boulders marking remnants of a lateral moraine in Coire Riabhach, Isle of Skye, Scotland.
Cuillin ridge – an arête – may be seen in the background. The peak in the right background is Sgurr nan Gillean – a horn.
