The Defiance Plateau, part of the geologic Defiance Uplift, is an approximately 75-mile (121 km) long,〔Arizona DeLorme Atlas, p. 26-27, 34-35, 44-45.〕 mostly north-trending plateau of Apache County, Arizona, and its east and southeast perimeter, are parts of San Juan and McKinley Counties, New Mexico. The west and southwest of the plateau region borders the east, southeast of the Painted Desert, where the Puerco River enters the desert, flowing southwest from New Mexico then meeting the Little Colorado River which flows northwest through the Painted Desert-(light tan & arc-shaped), to the Colorado River-(at the northeast of the Grand Canyon). The Puerco River is the plateau's border on the south and southeast; at the northwest, the Black Mesa is the northwest border, and the north of the Defiance Plateau is bounded by the south of the Chinle Valley, where Chinle Creek flows north to meet the San Juan River in southeast Utah. The north terminus region of the Defiance Plateau contains three canyons, with watercourses flowing due-west, as headwaters of Chinle Creek. The canyons are the Canyon de Chelly National Monument; two other canyons are southwest, part of the five canyon system, Little White House and Three Turkey Canyons. The Defiance Plateau is part of the Navajo Nation. At the plateau's southeast, on Black Creek lies the site of Window Rock, Arizona, the Navajo Nation capitol. The highpoint of the plateau is Fluted Rock, southwest of Sawmill, Arizona, .〔Arizona Road & Recreation Atlas, p. 71.〕 ==Description== The Defiance Plateau is the central area of an uplifted region. To the north/northeast are the Lukachukai Mountains, part of the Defiance Plateau border; they form a southeast section of Chinle Valley's border. South of the Lukachukais is the rest of the east border of the Defiance Plateau, the Chuska Mountains; the Chuskas trend northwest in the north; at the plateaus east, the Chuskas trend more southerly, and attached at the south is Manuelito Plateau, in New Mexico, the east border of the south-flowing Black Creek at the southeast perimeter region of the Defiance Plateau. 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「Defiance Plateau」の詳細全文を読む スポンサード リンク
