Clarence Rivers King was an American geologist, mountaineer and author. He was the first director of the United States Geological Survey from 1879 to 1881. Nominated by Republican President Rutherford B. Hayes, King was noted for his exploration of the Sierra Nevada mountain range.
Ferdinand Vandeveer Hayden was an American geologist noted for his pioneering surveying expeditions of the Rocky Mountains in the late 19th century. He was also a physician who served with the Union Army during the Civil War.
William Henry Holmes — known as W.H. Holmes — was an American explorer, anthropologist, archaeologist, artist, scientific illustrator, cartographer, mountain climber, geologist and museum curator and director.
The Franklin Mountains of Texas are a small range 23 miles (37 km) long, 3 miles (5 km) wide that extend from El Paso, Texas north into New Mexico. The Franklins were formed due to crustal extension related to the Cenozoic Rio Grande rift. Although the present topography of the range and adjoining basins is controlled by extension during rifting in the last 10 million years, faults within the range also record deformation during the Laramide orogeny, between 85 and 45 million years ago.
Josiah Edward Spurr (1870–1950) was an American geologist, explorer, and author. Born in Gloucester, Massachusetts, he was considered something of a failure as a youth, unsuited for the family fishing business, since on a voyage he invariably became seasick. Since he could not be a productive fisherman like his brothers, his parents decided he might as well go to college. After working his way through Harvard, he began his career with the Minnesota Geological Survey, making the first-ever geological map of the great Mesabi iron range in Minnesota.
Clarence Edward Dutton was an American geologist and US Army officer. Dutton was born in Wallingford, Connecticut on May 15, 1841. He graduated from Yale College in 1860 and took postgraduate courses there until 1862, when he enlisted in the 21st Connecticut Volunteer Infantry; he fought at Fredericksburg, Suffolk, Nashville and Petersburg. He was elected as a member to the American Philosophical Society in 1871.
Mount Conness is a 12,590 foot (3,840 m) mountain in the Sierra Nevada range, to the west of the Hall Natural Area. Conness is on the boundary between the Inyo National Forest and Yosemite National Park. The Conness Glacier lies north of the summit.
King Peak is the southernmost summit above 11,000 feet (3,400 m) in the Ruby Mountains of Elko County, in northeastern Nevada in the western United States. To the west is Rattlesnake Canyon, and to the east is Overland Creek Canyon, which drains into the Ruby Valley). The Ruby Crest National Recreation Trail passes just to the east on its way north from Overland Lake. The summit is located at about 29 miles (47 km) southeast of the community of Elko, in the Humboldt National Forest and the Ruby Mountains Wilderness.
James Terry Gardiner was an American surveyor and engineer.
Allium atrorubens is a species of wild onion known by the common name dark red onion. This plant is native to the southwestern United States where it grows in the sandy soils of the Mojave Desert, the Great Basin and higher-elevation deserts in Nevada, eastern California southwestern Utah, northwestern Arizona.
Richard D. Cotter, also known as Dick Cotter and R.D. Cotter, was an Irish born American member of the first California Geological Survey.
George Otis Smith was an American geologist.
Robert Thomas Hill was a significant figure in the development of American geology during the late 19th and early 20th centuries. As a pioneer Texas geologist, Hill discovered and named the Comanche series of the Lower Cretaceous, and was a lifelong student of the structure and stratigraphy of the Cretaceous deposits of Central Texas and neighboring regions.
Samuel Franklin Emmons was an American geologist. He was born in Boston, Massachusetts. He graduated from Harvard University in 1861 and studied at the Ecole des Mines in Paris, France, from 1862 to 1864 and at the Freiberg (Saxony) mining school in 1865. In May 1867, he was appointed assistant geologist under Clarence King on the American geological exploration of the fortieth parallel, and in July 1879 became geologist in charge of the Colorado division of the United States Geological Survey. He traveled extensively throughout the United States in connection with his work, and in 1870 made a survey, along with A. D. Wilson, of Mount Rainier, the highest and most inaccessible peak in the Cascade Range. The largest glacier in the contiguous United States, Emmons Glacier, is located along their survey route and is named after Emmons.
Allen David "A.D." Wilson was an American cartographer.
Colorado is a geologic name applied to certain rocks of Cretaceous age in the North America, particularly in the western Great Plains. This name was originally applied to classify a group of specific marine formations of shale and chalk known for their importance in Eastern Colorado. The surface outcrop of this group produces distinctive landforms bordering the Great Plains and it is a significant feature of the subsurface of the Denver Basin and the Western Canadian Sedimentary Basin. These formations record important sequences of the Western Interior Seaway, and as the geology of this seaway was studied, this name came to be used in states beyond Colorado, but was later replaced in several of these states with more localized names.
Arnold Hague was a United States geologist who did many geological surveys in the U.S., of which the best known was that for Yellowstone National Park. He also had assignments in China and Guatemala. He became a member of the U. S. Geological Survey in 1879 when it was first organized.
The Uinta Formation is a geologic formation in northeastern Utah. The name appears on a geologic map accompanying the Clarence King Fortieth Parallel report for 1876 but not defined until 1878 as the Uinta Group. As defined, it consisted of all Tertiary strata overlying the Green River Formation and was composed of coarse, conglomeratic sandstones, passing up into finer-grained sandstones and calcareous mudstones. Numerous vertebrate fossils were collected and described by Othniel C. Marsh of Yale University. The formation was subsequently subdivided into three informal horizons based on mammalian fossils. Horace Wood proposed the name Wagonhound Member for Uinta A+B and Myton Member for Uinta C. However, these names are not based on lithology, but on mammalian vertebrate faunas. For that reason, they have not been accepted as proper lithostratigraphic names.
The Pogonip Group is an Ordovician period geologic group located in southern Nevada and in Utah.
James Duncan Hague was an American mining engineer, mineralogist, and geologist.
