Explanation
Basket-of-eggs topography is a geomorphological term specifically associated with drumlins. Drumlins are swarms of oval, elongated hummocks composed of boulder clay or glacial till, formed by the movement of ice [1]. These landforms typically feature a blunt 'stoss' end and a tapering 'lee' end, aligned in the direction of glacial flow [1]. When drumlins occur in large clusters or swarms, the undulating landscape resembles a collection of eggs in a basket when viewed from above [1]. This distinctive topography is famously found in regions like County Down in Northern Ireland and the glaciated plains around the Great Lakes in North America. While other glacial features like eskers and moraines are depositional, they form ridges or irregular sheets rather than the specific egg-like clusters characteristic of drumlin swarms [2].
