The Lone Mountain Formation is a geologic formation in Utah.
The Silurian is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at 443.8 million years ago (Mya), to the beginning of the Devonian Period, 419.2 Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out.
The Wasatch Range is a mountain range in the western United States that runs about 160 miles (260 km) from the Utah-Idaho border south to central Utah. It is the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region. The northern extension of the Wasatch Range, the Bear River Mountains, extends just into Idaho, constituting all of the Wasatch Range in that state.
In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. A synclinorium is a large syncline with superimposed smaller folds. Synclines are typically a downward fold (synform), termed a synformal syncline, but synclines that point upwards can be found when strata have been overturned and folded.
The Mackenzie Mountains are a Canadian mountain range forming part of the Yukon-Northwest Territories boundary between the Liard and Peel rivers. The range is named in honour of Canada's second prime minister, Alexander Mackenzie. Nahanni National Park Reserve and Nááts'ihch'oh National Park Reserve are in the Mackenzie Mountains.
The Lone Peak Wilderness is a 30,088-acre (121.76 km2) wilderness area located within the Uinta and the Wasatch-Cache National Forest in the U.S. state of Utah.
The Silurian Shawangunk Formation is a mapped bedrock unit in eastern Pennsylvania, New Jersey, and New York. It is named for the Shawangunk Ridge for which it is the dominant rock type. The division of the Shawangunk between the Tuscarora Formation and Clinton Group has not been conclusively determined. The shift of nomenclature currently has the divide between Hawk Mountain and Lehigh Gap.
The Cedar Mountain Formation is the name given to a distinctive sedimentary geologic formation in eastern Utah. The formation was named for Cedar Mountain in northern Emery County, Utah, where William Lee Stokes first studied the exposures in 1944.
Cross Mountain is the highest peak in the Bear Pond Mountains, a sub range of the Appalachian Mountains. This grouping of mountains straddle the Maryland and Pennsylvania border.
The Canadian is the Lower or Early Ordovician in North America. The term is common in the older literature and has been well understood for more than a century. However it has no official recognition by the International Commission on Stratigraphy (ICS) and has been superseded by the more recently defined Ibexian series of western Utah.
Roundtop Hill is a mountain in Washington County, Maryland, southwest of the town of Hancock. The elevation at the summit is 1,358 feet (410 m).
The Confusion Range is a north-south trending mountain range in west-central Utah, United States. It is bounded by Snake Valley to the west, Tule Valley to the east, the Great Salt Lake Desert to the north, and the Ferguson Desert to the south. The range trends into the Burbank Hills, Mountain Home Range, and the Wah Wah Mountains to the south. In the central part of the range, an offshoot of the mountains to the west is known as the Conger Range. The Confusion Range is named for its "rugged isolation and confusing topography."
The Stonewall Formation is a stratigraphical unit of Late Ordovician to Early Silurian age in the Western Canadian Sedimentary Basin.
The Rumble in the Rockies, or Colorado–Utah football rivalry, is an American college football rivalry between the University of Colorado Buffaloes from Boulder and the University of Utah Utes of Salt Lake City. After nearly five decades of dormancy, the rivalry was revived in 2011, when both joined the Pac-12 Conference.
The Lone Ranger is a 1956 Western film based on The Lone Ranger television series, starring Clayton Moore and Jay Silverheels. The Lone Ranger was the first of two theatrical features based on the popular TV series of the same name; the other one being The Lone Ranger and the Lost City of Gold (1958). This 1956 film was Bonita Granville's last film appearance. She retired from the screen to marry Jack Wrather.
The Brassfield Formation, named by A.F. Foerste in 1906, is a limestone and dolomite formation exposed in Arkansas, Ohio, Kentucky, Indiana, Tennessee and West Virginia in the United States. It is Early Silurian in age and well known for its abundant echinoderms, corals and stromatoporoids. In Ohio, where the unit has escaped dolomitization, the Brassfield is an encrinite biosparite with numerous crinoid species.
The Laketown Dolomite is a dolomite geologic formation in Nevada and Utah. It preserves fossils dating back to the Silurian period.
The Lone Mountain Dolomite is a dolomite geologic formation in Nevada.
The Beaverfoot Formation is a stratigraphic unit of Late Ordovician to Early Silurian (Llandovery) age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains of British Columbia and Alberta, and the Purcell Mountains of British Columbia. It consists of carbonate rocks, and was named for the Beaverfoot Range at Pedley Pass southeast of Golden, British Columbia by L.D. Burling in 1922.
Edward B. Branson was an American geologist and paleontologist. He worked at the University of Missouri.
The geology of Utah includes rocks formed at the edge of the proto-North American continent during the Precambrian. A shallow marine sedimentary environment covered the region for much of the Paleozoic and Mesozoic, followed by dryland conditions, volcanism and the formation of the basin and range terrain in the Cenozoic. Utah is a state in the western United States.
