Te Henga (Bethells Beach) is a coastal community in the Auckland Region in the north of the North Island, New Zealand. The Māori name Te Henga, meaning sand, originally applied to a wide area of the lower Waitakere River valley, but in 1976 the New Zealand Geographic Board changed the name of the beach from Bethells Beach to Te Henga (Bethells Beach).〔(Te Henga Park Reserve Management Plan: Description of Te Henga Park ), Waitakere City, June 2002.〕 The beach is approximately 30 kilometres north-west of Auckland City, at the mouth of the Waitakere River where it flows into the Tasman Sea. One of several popular resorts in the area (others include Muriwai, Piha and Karekare), it experiences a population explosion in summer when Aucklanders head to the sea. == History == The Te Henga Valley shows evidence of human settlement dating back over 1000 years. The cultural history of the area is of archaeologically significant sites, including food gathering areas, pā, walkways, canoe landings and sacred places.〔 The arrival of Europeans in the 19th century led to major changes in the character and shape of Bethells Beach. The most significant of these changes was the clearing of the land for timber and pastoral farming which began in 1854 and continued until the 1920s. In addition, a dam was constructed on the Waitakere River in the 1920s, drastically altering the level of the riverbed and reducing the outflow of water to the sea.〔 John Bethell negotiated with the Waitakere County Council to sell the land that is now known as Te Henga Park. The Council considered the beach and park area would provide excellent recreation facilities for residents of Auckland. Te Henga was recognised as a place of regional significance.〔 == Geology== The sand dunes have accumulated in several phases over the last 4,500 years. This accumulation has occurred since sea levels returned to about their present levels following the last glaciation 6,500 years ago. These sands contain quantities of black titanomagnetite derived from the volcanic rocks of Taranaki and carried north by coastal currents. The dunes continually move in a dynamic coastal process. There are three dune-impounded lakes: Lake Wainamu, Lake Kawaupaka and Lake Waiataru. 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「Te Henga (Bethells Beach)」の詳細全文を読む スポンサード リンク
