 note = {A circular hole was discovered on the downstream side of a glacier dam in the Yatude Valley, Langhovde, East Antarctica, during the 2005-2006 austral summer. The opening of this hole is the first opportunity enabling us to observe the interior of the dam. The opening led to a large cave in the dam, raising the possibility of meltwater drainage through the dam. The Yatude Valley is an approximately U-shaped fluvial valley. The valley floor has been incised to form a box-shaped inner valley that contains fluvial terraces and large boulders upon the valley floor. The origin of these features can be explained by a large amount of running water; however, we consider it unlikely that a regular current has flowed through this site for a long period. Instead, it is more likely that large quantities of lake water have been periodically discharged due to collapse of the glacier dam or spilling out through a tunnel channel within the cave. The discovered hole and the ice cave are key features in understanding the historical development of the Yatude Valley in relation to the melting history of the Antarctic ice sheet., 2005-2006年の夏季に，ラングホブデ・やつで沢上流にある氷河ダムの下流側に円形の穴が開いているのが確認された。冬季にこの穴から氷河ダム内に入り，内部が大きな空洞となっていることを発見した。やつで沢は直線的に伸びるU字谷で，氷河ダム直下からはＵ字谷底がさらに函谷状に浸食された二段構造をなす。氷洞内の側壁も同様に垂直の基盤岩からなり，この函谷に地形的に連続することから，ダム内の空洞は氷河底洪水吐をなしているものと考えられる。これらの事実は，過去および将来において，氷河ダムから排水が発生したりダム自体が決壊したりする可能性を強く示唆し，やつで沢の地形発達や上流の湖の盛衰を考える上で重要な鍵となる。},
