For management purposes, the Wyperfeld National Park is managed with the Hattah-Kulkyne National Park, Murray-Sunset National Park, Lake Albacutya Park and Murray-Kulkyne Park as part of the Victorian Mallee Parks.〔 ==History== Like most of north-western Victoria, Wyperfeld was a shallow sea from about 25 million years ago until fairly recent times. The current landforms took shape as the sea gradually retreated, leaving a vast expanse of sandy sediment which, as it dried, was formed into sand dunes during the period 40,000 to 15,000 years ago. Before European settlement, the network of ephemeral lakes filled and emptied, on average, about every 20 years, typically remaining dry for about half that period at a time. More recently, agricultural irrigation and drainage projects in the surrounding areas have cut off a significant part of Wyperfeld's water supply, and the lakes have not been completely filled since 1975, and had drained again just two years later. 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「Wyperfeld National Park」の詳細全文を読む スポンサード リンク
