''For the islands in the Bismarck Archipelago see Admiralty Islands'' The Admiralty Group of islets consists of eight rocky outcrops within 2 km of the north of Lord Howe Island: Soldier’s Cap, Sugarloaf, Noddy, South Island, Tenth of June, North Rock, Flat Rock and Roach Island. Roach Island is the largest being about 15 ha in area, 800 m long and 86 m high, with a much-photographed 15 m tall tunnel at its northern end. The basalt lava flows are crossed by many dikes. The vegetation consists of grasses, sedges and a few bushes. These islets are noted for the nesting populations of seabirds in spring and summer in greater numbers than anywhere else on Lord Howe Island, mainly sooty terns, masked boobies and brown noddies.〔 Boat trips take visitors to Roach Island for a bird colony experience.〔 ==See also== * Admiralty 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Admiralty Group」の詳細全文を読む スポンサード リンク
