Mount Ayanganna is a sandstone tepui in the Pakaraima Mountains of western Guyana, 85 kilometres east of Mount Roraima at .〔(BDG Plant Collectors: David Clarke ). National Museum of Natural History.〕 With a height of 2,041 metres (6,696 feet) it is the easternmost tepui taller than 2,000 metres. It is part of the Guiana Shield. The slopes of Ayanganna are covered in tall-canopy lower montane forest, up to about 1100 metres. Above this elevation, there is a series of "steps" - relatively flat plateaus separated by steeper slopes. The poorly drained plateaus support low-canopy forest or terrestrial bromeliads. The slopes support medium-canopy high-montane forest. The amphibians and reptiles of Ayanganna have been surveyed. Mount Ayanganna is fully within Guyanese territory and is surrounded by rainforest. Ever since Guyana became a Republic on 23 February 1970, the national flag is hoisted ceremoniously each year on Mount Ayanganna on the eve of the country's Republic Anniversary by members of the Guyana Defence Force (GDF). The GDF named their Georgetown base after Mount Ayanganna. On 1 November 2005 28 female soldiers hoisted the national flag on the summit after a two day climb. ==References== 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「Mount Ayanganna」の詳細全文を読む スポンサード リンク
