Abstract from DBPedia
    A drumlin, from the Irish word droimnín ("littlest ridge"), first recorded in 1833, in the classical sense is an elongated hill in the shape of an inverted spoon or half-buried egg formed by glacial ice acting on underlying unconsolidated till or ground moraine. Assemblages of drumlins are referred to as fields or swarms; they can create a landscape which is often described as having a 'basket of eggs topography'. The low ground between two drumlins is known as a dungeon; dungeons have colder microclimates in winter from settling cold air.

    氷堆丘(ひょうたいきゅう)とは、氷河によって形成された丘である。なお、氷堆丘は、英語の「drumlin」をそのまま音訳して、ドラムリンと片仮名表記される場合もあるものの、本稿では以降「氷堆丘」という表記に統一する。ちなみに、この英語の「drumlin」というのは、元々アイルランド語で「小さな尾根」を意味する「droimnin」という語が語源である。
