Drumlin formation remains scientifically unresolved. Drumlins are elongated hills blunt on one end and tapered on the other They form beneath glaciers, not outside them Drumlin fields exist near Rochester, New York and in the Hudson Valley
Drumlins are elongated hills blunt on one end, tapered on the other, forming beneath glaciers. Despite 150 years of study, scientists haven't reached consensus on how they form. John Shaw's research suggests subglacial meltwater flow rather than ice itself. Drumlin fields exist near Rochester, New York and the Hudson Valley, with south-southeast angles indicating flow direction. 🏔️❓ 08:30-12:30
