Roald H. Fryxell
Roald Hilding Fryxell (February 18, 1934 – May 18, 1974) was an American educator, geologist and archaeologist. He was a Professor of Anthropology at Washington State University (WSU) and pioneer in the interdisciplinary field of geoarchaeology, with a career that involved work on monumental projects in North America and even outer space. Early life Roald H. Fryxell, or later known as "Fryx" to his friends, was born on February 18, 1934, in Moline, Illinois. His parents were Fritiof Fryxell, a renowned mountain climber, writer, and Professor of Geology, and Regina Holmén Fryxell, an organist and music teacher.Friends of Roald Fryxell (1978).

Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth an ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Monumental Dam
Lower Monumental Lock and Dam is a hydroelectric, concrete, run-of-the-river dam in the northwest United States. Located on the lower Snake River in southeast Washington, it bridges Franklin and Walla Walla counties; it is south of Kahlotus and north of Walla Walla. Construction began in June 1961, and the main structure and three generators were completed in 1969, with an additional three generators finished in 1981. Generating capacity is 810 megawatts, with an overload capacity of 932 MW. The spillway has eight gates and is in length. Built and operated by the U.S. Army Corps of Engineers, Lower Monumental Dam is part of the Columbia River Basin system of dams. Behind the dam, Lake Herbert G. West is the reservoir; it extends east to the base of Little Goose Dam. Lake Sacajawea, formed from Ice Harbor Dam, runs southwest, downstream from the base of the dam. ;Navigation lock * Single-lift * Width: * Length: See also *List of dams in the Columbia Riv ...

Fryxell (crater)
Fryxell is a small lunar impact crater that lies amidst the western inner ring of the Montes Rook. It is named for Roald H. Fryxell, an American geologist. It was previously designated Golitsyn B, a satellite of Golitsyn, before being assigned a name by the IAU. This crater is located on the Moon's far side, at the extreme edge of the region of the surface sometimes brought into view of the Earth due to libration. Even under rare conditions of favorable lighting and libration, this area would only be seen from the side amidst a rugged range of mountains. Thus this crater is best observed from orbit. This formation is roughly circular, but with a slightly polygonal appearance. It is a bowl-shaped formation with a darker interior floor that is relatively featureless. The inner walls of Fryxell have a higher albedo Albedo (; ) is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black b ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle.

Palouse River
The Palouse River is a tributary of the Snake River in Washington and Idaho, in the northwest United States. It flows for U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed May 3, 2011 southwestwards, primarily through the Palouse region of southeastern Washington. It is part of the Columbia River Basin, as the Snake River is a tributary of the Columbia River. Its canyon was carved out by a fork in the catastrophic Missoula Floods of the previous ice age, which spilled over the northern Columbia Plateau and flowed into the Snake River, eroding the river's present course in a few thousand years. Course The Palouse River flows from northern Idaho into southeast Washington through the Palouse region, named for the river. The river originates in Idaho in northeastern Latah County, in the Hoodoo Mountains in the St. Joe National Forest. It flows westward, near State Highway 6, as it nears the state line.
