Menan Buttes
The North and South Menan Buttes in southeastern Idaho are two of the world's largest volcanic tuff cones. The two cones, with four smaller associated cones, align along a north-northwest line and comprise the Menan Complex. The buttes rise about 800 feet (250 m) above the surrounding Snake River plain and are late Pleistocene in age, dating to approximately 10,000 YBP (Years Before Present). The South Menan Butte is currently in private hands, however North Menan Butte is publicly owned and has been designated as a National Natural Landmark and a Research Natural Area by the United States Congress. The US Bureau of Land Management designated the North Butte as an Area of Critical Environmental Concern (ACEC). The volcanoes forming the two major Menan Buttes were created when basaltic magma came into contact with a shallow aquifer or with the precursor of the modern Snake River. Particles of volcanic glass called tachylite were created as the water turned to steam and explosiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madison County, Idaho
Madison County is a county located in the U.S. state of Idaho. As of the 2020 census, the population was 52,913. The county seat and largest city is Rexburg. Madison County is part of the Rexburg, Idaho micropolitan area, which is also included in the Idaho Falls metropolitan area.

Diamond Head, Hawaii
Diamond Head is a volcanic tuff cone on the Hawaiian island of Oahu and known to Hawaiians as Lēahi (). The Hawaiian name is most likely derived from ''lae'' (browridge, promontory) plus ''ahi'' (tuna) because the shape of the ridgeline resembles the shape of a tuna's dorsal fin. Its English name was given by British sailors in the 19th century, who named it for the calcite crystals on the adjacent beach. Geology Diamond Head is part of the system of cones, vents, and their associated eruption flows that are collectively known to geologists as the Honolulu Volcanic Series, eruptions from the Koolau Volcano that took place long after the volcano formed and had gone dormant. These eruptive events created many of Oahu's well-known landmarks, including Punchbowl Crater, Hanauma Bay, Koko Head, and Mānana Island in addition to Diamond Head. Diamond Head, like the rest of the Honolulu Volcanic Series, is much younger than the main mass of the Koolau Mountain Range. While the ...

Pleistocene Volcanoes
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Geology Of Idaho
The Geology of Idaho is complex, with outcroppings of differing ages of volcanics, undifferentiated metamorphics and sedimentary structures. Idaho Geologic Survey Since 1919, the Idaho Geological Survey (formerly Bureau of Mines and Geology) has studied and reported on the general and environmental geology of the state. The Survey also studies and reports on the water (both surface and ground), mineral data, and energy assets of the state. Geologists and hydrologists on staff at the Survey research, make reports based on their research, and produce maps for the state. The University of Idaho administers the Survey as a special program with offices in Moscow and in Boise. Regions Panhandle The region of the Idaho Panhandle reaches from the Canada–US border south to Interstate Highway 90. The area consists generally of Precambrian sedimentary formations, some of which have metamorphosed into slates. The area includes the Selkirk Mountains, the Purcell trench and the Cabi ...

Extinct Volcanoes
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Yellowstone Hotspot
The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession of caldera-forming eruptions. The resulting calderas include the Island Park Caldera, Henry's Fork Caldera, and the Bruneau-Jarbidge caldera. The hotspot currently lies under the Yellowstone Caldera. The hotspot's most recent caldera-forming supereruption, known as the Lava Creek Eruption, took place 640,000 years ago and created the Lava Creek Tuff, and the most recent Yellowstone Caldera. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot. Snake River Plain The eastern Snake River Plain is a topographic depression that cuts across Basin and Range Mountain structures, more or less parallel to North American plate mot ...

Island Park Caldera
The Island Park Caldera, in the U.S. states of Idaho and Wyoming, is one of the world's largest calderas, with approximate dimensions of 80 by 65 km. Its ashfall is the source of the Huckleberry Ridge Tuff that is found from southern California to the Mississippi River near St. Louis. This super-eruption of approximately occurred 2.1 Ma (million years ago) and produced 2,500 times as much ash as the 1980 eruption of Mount St. Helens. Island Park Caldera has the smaller and younger Henry's Fork Caldera nested inside it. The caldera clearly visible today is the later Henry's Fork Caldera, which is the source of the Mesa Falls Tuff. It was formed 1.3 Ma in an eruption of more than . The two nested calderas share the same rim on their western sides, but the older Island Park Caldera is much larger and more oval and extends well into Yellowstone National Park.Newhall and Daniel Dzurisin, 1988, "Historical Unrest at Large Calderas of the World", ''U.S. Geological Survey Bullet ...
