Kelly Butte Natural Area is a city park of about in southeast Portland in the U.S. state of Oregon, just east of Interstate 205. The park is named after pioneer Clinton Kelly, who settled the area east of the Willamette River in 1848.〔(【引用サイトリンク】title=Kelly Butte Natural Area )〕 It is part of the Boring Lava Field, an extinct Plio-Pleistocene volcanic field that contains 32 cinder cones and shield volcanoes in or near Portland.〔 The butte contains a now-sealed concrete bunker built as a civil defense emergency operations center in 1955–56 and later used for emergency dispatching.〔http://www.portlandonline.com/transportation/index.cfm?a=384903&c=53762〕 It appears in the film ''A Day Called X''. ==Human history== In 1848, pioneer Clinton Kelly settled in the Willamette Valley in the area that is today southeast Portland. Present-day Clinton Street and Clinton Park bear his name. Clinton had five sons, one of whom, Plympton Kelly, established a farm on or near Kelly Butte. According to a 1906 obituary of Plympton Kelly, the farm was known as the Kelly Butte farm. In 1906, a prison and rock quarry opened on the site, where prisoners sentenced to hard labor would break rocks. In 1924, two corrections officers and a prisoner were killed when setting explosives at the quarry.〔(【引用サイトリンク】 url=http://web.archive.org/web/20060618023040/http://www.co.multnomah.or.us/sheriff/memorial.htm )〕 The facility operated until the 1950s, providing cheap labor to crush rocks that were used for Portland's roads.〔 After the prison and quarry closed, a civil defense bunker opened on the site in 1956. The bunker was later retrofitted and served as an emergency services dispatch center from 1974 through 1994. In 1994 it was shuttered, and in 2006 it was permanently sealed off.〔 From 1920 to 1960, Kelly Butte was home to a sixty-bed municipal hospital that isolated patients with infectious diseases. In 1968 a ten-million gallon water tank was built in its place.〔 In 2010, the Portland City Council voted to replace the old water tank with a 25-million gallon underground reservoir. The new reservoir will serve as a replacement for Mount Tabor's three open-air reservoirs.〔 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「Kelly Butte Natural Area」の詳細全文を読む スポンサード リンク
