  USGS : United States Geological Survey : a research agency of the US Department of the Interior, established in 1879. It is responsible for interpreting and mapping the geology, hydrology, and topography of the United States and its territories and for investigating and appraising mineral, energy, and water resources.

UTC : Coordinated Universal Time : a practical international time scale which is identical with International Atomic Time (TAI) except that from time to time a leap second is added to ensure that, when averaged over a year, the Sun crosses the Greenwich meridian at noon UTC to within 0.9 s. The dates of application of the leap second are decided by the International Earth Rotation Service (IERS); this way UTC is kept within 0.9 seconds of Greenwich Mean Time (GMT).

In 1970 the Coordinated Universal Time system was devised by an international advisory group of technical experts within the International Telecommunication Union (ITU). The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion. Since unanimous agreement could not be achieved on using either the English word order, CUT, or the French word order, TUC, the acronym UTC was chosen as a compromise.



history : Amerindians

  Utes : an ethnically related group of American Indians. Prior to the arrival of white settlers, the Utes occupied significant portions of what are today eastern Utah, western Colorado and parts of New Mexico and Wyoming; ancestors of the Ute appear to have occupied these areas for at least a thousand years. The Utes were never a unified group; instead, the Utes consisted of numerous nomadic bands that maintained close associations with other neighboring groups. Some of the larger groups included the Moache, Capote, Uncompahgre, White River, Uintah, Pahvant, Timanogots, San Pitch, Moanumts, Sheberetch and Weeminuche. The native Ute language belongs to the Uto-Aztecan (Shoshone) family of languages and is a dialect of Southern Numic. Nowadays Utes are living primarily in three Ute tribal reservations: Uintah-Ouray in northeastern Utah; Southern Ute and Ute Mountain in southwestern Colorado.

history : Amerindians

Uto-Aztecan (also Uto-Aztekan, Shoshone) : a Native American language family; it is one of the largest (both in geographical extension and number of languages) and most well-established linguistic families of the Americas. The Uto-Aztecan languages are found from the Great Basin of the western United States (Oregon, Idaho, Utah, California, Nevada, Arizona), through Mexico. Utah is named after the indigenous Uto-Aztecan Ute people. Classical Nahuatl, the language of the Aztecs, and its modern relatives are part of the Uto-Aztecan family. Other American Indian groups with native Shoshonean dialects include the Bannocks, Comanches, Chemehuevi, Goshutes, Paiutes and Shoshones.
