词条 | Mesa Verde National Park |
释义 | Mesa Verde National Park park, Colorado, United States ![]() ![]() national park in southwestern Colorado, U.S., established in 1906 to preserve notable prehistoric cliff dwellings (cliff dwelling); it was designated a World Heritage site in 1978. Occupying a high tableland area of 81 square miles (210 square km), it contains hundreds of pueblo (Indian village) ruins up to 13 centuries old. The most striking are multistoried apartments built under overhanging cliffs. Besides the ruins, the park has some spectacular and rugged scenery. The park occupies part of a large sandstone plateau rising more than 8,500 feet (2,600 metres) above sea level that slopes gently to the south. Stream erosion during the past two million years cut deep canyons into the plateau, leaving narrow strips of high tableland, or mesa, between the canyons. Water erosion formed niches and alcoves of various sizes in the sandstone of these canyon walls (where the cliff dwellings are located). On the top of these mesas there are windblown deposits of fertile reddish soil (loess). The climate is semiarid and, according to the examination of tree rings, has changed little during the past 600 years. The area's plant life is adapted to the semiarid climate: piñon-juniper forest is the dominant vegetation on the mesas, and sagebrush is the characteristic vegetation on the canyon floors. Elk are the most common large animals, and there are a few bears and mountain lions and many smaller mammals in the park. Snakes and lizards also abound, as do birds. About 550 CE, Basketmaker peoples, direct ancestors of the region's later Ancestral Pueblo (Ancestral Pueblo culture) (Anasazi) peoples, moved into the Mesa Verde area. They made pottery and built clusters of semi-subterranean pit houses on the mesa tops at an elevation of 7,000 feet (2,000 metres), where they also cultivated corn (maize), beans, and squash. There was usually sufficient rainfall for their crops, and springs and seeps provided drinking water. About 750 CE, surface dwellings began to be constructed, consisting of houses with vertical walls and flat roofs, all joined together in long rows; archaeologists designate this as the Pueblo I period. Sandstone began to be more commonly used in house construction, and one or more subterranean pit rooms (kivas), probably used for ceremonial purposes, were dug in front of these row houses. Houses with more than one story and round towers also began to be built. ![]() ![]() By 1300, following the Great Drought (1276–99), most of the people had left Mesa Verde, moving south, according to archaeological evidence, into what is now New Mexico and Arizona. These people are among the ancestors of the present-day Pueblo Indians. Several of the cliff dwellings, including Cliff Palace, are open to visitors; camping is available, and a lodge is open in the park in the summer. |
