Brownfield is a city in Terry County, Texas, United States. The population was 9,657 at the 2010 census. It is the county seat of Terry County〔(【引用サイトリンク】accessdate=2011-06-07 )〕 near Lubbock in West Texas. ==Geography== According to the United States Census Bureau, Brownfield has a total area of , of which 0.32% is covered by water. Brownfield lies in the center of Terry County, within the southern portion of the South Plains and Llano Estacado. The city rests on a windblown deposit called the Blackwater Draw Formation, which is underlain by a thick layer of caliche, referred to locally as the "Caprock". Beneath the caliche layer lies fluvial deposits called the Ogallala Formation, which contains a portion of the vast Ogallala Aquifer. The Caprock Escarpment, about 50 miles east, forms a rather precipitous drop of about and exposes various geologic layers. In early days, climbing the caprock escarpment was not easy for horse-drawn covered wagons. The only terrain variation lies at the south end of the city, where Lost Draw carves a channel that runs across the entire county. Lost Draw formed over 10,000 years ago at the end of the last ice age when the climate of the area was much wetter. When the vast glaciers of the north retreated, they left numerous dry river channels crisscrossing the Llano Estacado. When settlers during the 1800s ventured across this area, they often went into these channels expecting to find water; however, unless significant rains had occurred recently, their search was in vain, with many of the parties becoming "lost", hence the name, Lost Draw. The most notable geographic feature of Brownfield remains its red soil. The soil creates an almost iridescent red color during sunrise and sunset due to the high iron oxide content. 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「Brownfield, Texas」の詳細全文を読む スポンサード リンク
