The Minnesota Geological Survey is a unit of the Newton Horace Winchell School of Earth Sciences at the University of Minnesota. [1]
The Minnesota Geological Survey was established by the Minnesota State Legislature in 1872 as the Geological and Natural History Survey of Minnesota, and Newton Horace Winchell was appointed as its director. [2]
Taconite is a variety of iron formation, an iron-bearing sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He believed the sedimentary rock sequence hosting the iron-formation was correlative with the Taconic orogeny of New England, and referred to the unfamiliar and as-yet-unnamed iron-bearing rock as the 'taconic rock' or taconyte.
Newton Horace Winchell was an American geologist chiefly notable for his six-volume work The Geology of Minnesota: Final Report of the Geological and Natural History Survey of Minnesota, which was prepared by Winchell and his assistants. A bibliography of his publications by Warren Upham in the Bulletin of the Geological Society of America contains almost 300 titles.
Warren Upham was an American geologist, archaeologist, and librarian who is best known for his studies of glacial Lake Agassiz.
The Misquah Hills are a range of mountains in northeastern Minnesota, in the United States. They are located in or near the Boundary Waters Canoe Area Wilderness within Superior National Forest. Eagle Mountain, the highest point in Minnesota at 2,301 feet, is considered to be part of the Misquah Hills.
Winchell is a surname. It may refer to:
Ulysses Sherman Grant was an American geologist. He was the son of Lewis A. Grant and Mary Helen Pierce.
Abita Lake is a lake in West Cook, Minnesota, which, at an elevation of 2,040.19 feet (621.85 m) above sea level, is Minnesota's ninth highest named lake. Prior to modern surveys, the lake was once believed to be Minnesota's highest elevation lake.
Charles Henry Hitchcock was an American geologist.
Constance Mabel Winchell was an American librarian. Winchell worked at Columbia University for thirty-eight years before retiring in 1962. She is best remembered for producing the seventh and eighth editions of the Guide to Reference Books. In 1999, American Libraries included Constance Winchell in a list of 100 most influential individuals in the field of library and information science.
Brule Lake is a lake in Cook County, Minnesota. It is situated between two long sills in the Superior Upland, causing the lake to be eight times longer east and west than it is north and south. Out of the opposite ends flow the Temperance River and the South Brule, a tributary of the Brule River. Brule Lake was logged heavily in the early 1900s, and the region around it was consumed in 1929 by a logging-related forest fire which bears Brule Lake's name. Now the lake is part of the protected Boundary Waters Canoe Area, a federal wilderness area for which Brule Lake serves as an entrance point.
Alexander Winchell was a United States geologist who contributed to this field mainly as an educator and a popular lecturer and author. His views on evolution aroused controversy among his contemporaries; today the racism of these views is more cause for comment.
Winchell Lake is a lake in Cook County, Minnesota, in the United States. It is most commonly accessed from Brule Lake or Poplar Lake.
Ima Lake is a lake in Lake County, in the U.S. state of Minnesota.
Newton Lake is a lake in Lake County, in the U.S. state of Minnesota.
Phragmolites is an extinct genus of molluscs in the family Bucaniidae, paleozoic molluscs of uncertain position possibly being either Gastropods or Monoplacophorans in the superfamily Bellerophontoidea.
Mount Seattle is a 10,350-foot (3,150 m) peak in the Saint Elias Mountains of Alaska in the United States. It was named for the city of Seattle, home of the "camp hands" of a 19th-century National Geographic Society–United States Geological Survey scientific expedition to the Hubbard Glacier and Mount Saint Elias. It is called the "most prominent Alaskan coastal peak" and blocks sight of larger inland peaks, even Mount Logan nearly twice its height.
Adelaide George Bennett was an American teacher, poet, and botanist. She is remembered for her poems which described Native American life and the Red Pipestone Quarry.
Winchell Trail is a five-mile (8 km) round trip, pedestrian-only trail in Minneapolis, Minnesota, United States, that runs along the west side of the Mississippi River between Franklin Avenue South and East 44th Street. Popular with bird watchers and naturalists, the rustic trail provides Upper Mississippi River gorge access and views. The trail is separate from the adjacent multi-use bicycle path, taking hikers past sandy beaches, an oak savanna restoration project, and the floodplain forest. The trail has multiple access points and the section from East 38th Street to East 44th Street is paved. Described as moderate and for all hiking skill levels, the out-and-back Winchell Trail has total elevation gain of 501 feet (153 m). Portions of the trail can be hiked in near solitude as its age and general destitute make it a widely forgotten place to explore.
Alexander Newton Winchell was an American geologist who pioneered spectroscopic and X-ray crystallographic studies on minerals. He wrote an influential textbook, the Elements of optical mineralogy which went into several editions.
Horace Vaughn Winchell was an American geologist who specialized in mining geology. Unlike his father, geologist Newton Horace Winchell, he worked mainly in the industry. He edited the journal Economic Geology which he also helped in establishing.
