Definition

Streamlined hill, typically ovoid to elongate, in previously ice sheet/glacier affected terrains.

Category

A type of subglacial streamlined hill.

Description

A streamlined hill that occurs mostly in glacial sediments (Menzies 1979; Clark et al. 2009; Shaw 2002; Stokes et al. 2011). They are ubiquitous on the now-exposed beds of former ice sheets, where they form fields or “flow-sets” that contain hundreds to thousands of individual drumlins with their long axis orientated parallel to the former ice flow direction (Boulton and Clark 1990; Fig. 1). Geophysical techniques have also detected their presence and formation beneath extant ice sheets, e.g., in Antarctica (King et al. 2007; Smith et al. 2007), and they have also been seen to emerge from receding glacier margins (Johnson et al. 2010).
