- Drumlin - Wikipedia
A drumlin, from the Irish word droimnín ("little ridge"), first recorded in 1833, in the classical sense is an elongated hill in the shape of an inverted spoon or half-buried egg [1] [2] formed by glacial ice acting on underlying unconsolidated till or ground moraine
- Drumlin | Glacial Landform, Moraine Eskers | Britannica
Drumlin, oval or elongated hill believed to have been formed by the streamlined movement of glacial ice sheets across rock debris, or till The name is derived from the Gaelic word druim (“rounded hill,” or “mound”) and first appeared in 1833 Drumlins are generally found in broad lowland regions,
- Drumlins - U. S. National Park Service
The classic drumlin shapes is a hill that highest on its up-glacier end and tapers gently from there, like a half-buried egg Not all drumlins taper like this, though Because they have been streamlined by flowing ice, scientists often use them to understand past glacier flow directions They are longest in the direction of flow

Smith-Reiner Drumlin Prairie by Joshua Mayer Drumlins are elongated hills that form at a glacier's bed and parallel the ice flow direction Wisconsin is home to one of the largest concentrations of drumlins in the world Southern Wisconsin alone has over 5,000 drumlins

ADDED: The formation of drumlins, and hence also their characteristics is too complex to be explained in a short answer here Three scientific papers that will help gaining a deeper understanding of drumlin formation are (I suggest googling on the titles to find copies): Patterson, C J , Hooke, R L , 1995 Physical environment of drumlin formation
- Drumlins - The University of Sheffield
Drumlin formation The timing or synchroneity of drumlin formation within a field remains unknown Some researchers deem drumlin formation as occurring close to ice margins and believe fields are built up incrementally as the margin retreats, whereas others believe that extensive patterns of drumlins may have formed approximately synchronously under wide swathes of an ice sheet
- Drumlins - Michigan Technological University
Drumlins form in clusters apparently near the terminus of glaciers The mechanisms are debated They appear to have important interpretive value for direction and rate of glacial movement
