USGS in the context of "Reston, Virginia"

The Great Basin Divide in the western United States is the ridgeline that separates the Great Basin from the Pacific Ocean watershed, which completely surrounds it.

The Great Basin is the largest set of contiguous endorheic watersheds of North America, including six entire USGS watershed subregions. It contains the watersheds of several large prehistoric and still-existing lakes, most notably Lake Bonneville, Lake Lahontan, Lake Manly, and the Salton Sea. As such, it occupies most of present-day Nevada, about half of Utah, large parts of eastern California and Oregon, and small parts of Idaho, Wyoming, and Baja California. The arid climate of this area ensures that none of the major lake basins are filled to overflowing, and thus no precipitation falling into them reaches the sea.

Planetary cartography, or cartography of extraterrestrial objects (CEO), is the cartography of solid objects outside of the Earth. Planetary maps can show any spatially mapped characteristic (such as topography, geology, and geophysical properties) for extraterrestrial surfaces. Some well-known examples of these maps have been produced by the USGS, such as the latest geological map of Mars, but many others are published in specialized scientific journals.

Yushu Tibetan Autonomous Prefecture (Tibetan: ཡུལ་ཤུལ་བོད་རིགས་རང་སྐྱོང་ཁུལ།, ZWPY: Yüxü Poirig Ranggyong Kü, Chinese: 玉树藏族自治州; pinyin: Yùshù Zàngzú Zìzhìzhōu, retranscribed into Tibetan as ཡུལ་ཤུལ།), also transliterated as Yüxü or Yulshul, is an autonomous prefecture of Southwestern Qinghai Province, China. Largely inhabited by Tibetans, the prefecture has an area of 188,794 square kilometres (72,894 sq mi) and its seat is located in the town of Gyêgu in Yushu County, which is the place of the old Tibetan trade mart of Jyekundo. The official source of the Yellow River lies within the prefecture. Historically, the area belongs to the cultural realm of Kham in Eastern Tibet.

On 14 April 2010, an earthquake struck the prefecture, registering a magnitude of 6.9 (USGS, EMSC) or 7.1 (Xinhua). It originated in the Yushu Tibetan Autonomous Prefecture, at 07:49 local time.

The Cumberland Mountains are a mountain range in the southeastern section of the Appalachian Mountains. They are located in western Virginia, southwestern West Virginia, the eastern edges of Kentucky, and eastern middle Tennessee, including the Crab Orchard Mountains. Their highest peak, with an elevation of 4,223 feet (1,287 m) above mean sea level, is High Knob, which is located near Norton, Virginia.

According to the USGS, the Cumberland Mountain range is 131 miles (211 km) long and 20 miles (32 km) wide, bounded by the Russell Fork on the northeast, the Pound River and Powell River on the southeast, Cove Creek on the southwest, and Tackett Creek, the Cumberland River, Poor Fork Cumberland River, and Elkhorn Creek on the northwest. The crest of the range forms the Kentucky and Virginia boundary from the Tennessee border to the Russell Fork River.

The U.S. Interior Highlands is a mountainous region in the Central United States spanning northern and western Arkansas, southern Missouri, eastern Oklahoma, and southern Illinois. The name is designated by the United States Geological Survey to refer to the combined subregions of the Ouachita Mountains south of the Arkansas River and the Ozark Plateaus north of the Arkansas. The U.S. Interior Highlands is one of few mountainous regions between the Appalachians and Rockies.

A mud volcano or mud dome is a landform created by the eruption of mud or slurries, water and gases. Several geological processes may cause the formation of mud volcanoes. Mud volcanoes are not true igneous volcanoes as they do not produce lava and are not necessarily driven by magmatic activity. Mud volcanoes may range in size from less than a meter high and 1 or 2 meters across, to 700 meters tall and 10 kilometers wide. Smaller mud exudations are sometimes referred to as mud-pots.

The mud produced by mud volcanoes is mostly formed as hot water, which has been heated deep below the Earth's surface, begins to mix and blend with subterranean mineral deposits, thus creating the mud slurry exudate. This material is then forced upwards through a geological fault or fissure due to local subterranean pressure imbalances. Mud volcanoes are associated with subduction zones and about 1100 have been identified on or near land. The temperature of any given active mud volcano generally remains fairly steady and is much lower than the typical temperatures found in igneous volcanoes. Mud volcano temperatures can range from near 100 °C (212 °F) to occasionally 2 °C (36 °F), some being used as popular "mud baths".

Kendrick Peak or Kendrick Mountain is one of the highest peaks in the San Francisco volcanic field north of the city of Flagstaff in the U.S. state of Arizona and is located on the Coconino Plateau in Coconino County.

Kendrick Peak rises to a height of 10,425 feet (3,178 m), which makes it the 11th or 12th tallest summit (depending on the source) in Arizona. Kendrick Peak is a lava dome between 2.7 and 1.4 million years old consisting primarily of dacite and rhyolite flows that were partly buried by andesite according to the USGS.

A digital raster graphic (DRG) is a digital image resulting from scanning a paper USGS topographic map for use on a computer. DRGs created by USGS are typically scanned at 250 dpi and saved as a TIFF. The raster image usually includes the original border information, referred to as the "map collar". The map file is UTM projected and georeferenced to the surface of the Earth. DRG's are regularly used in GIS applications. DRGs were first produced in 1995.

A GIS file format or geospatial file format is a standard for encoding geographical information into a computer file. It is a specialized type of file format for use in geographic information systems (GIS), remote sensing image processing tools, and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes. They have been created by government mapping agencies (such as the USGS or National Geospatial-Intelligence Agency), GIS software vendors, standards bodies such as the Open Geospatial Consortium, informal user communities, and even individual developers.
