Charlotte Whale
The Charlotte whale is the skeleton of a beluga whale that was found buried in sediment near Charlotte, Vermont, Charlotte, Vermont in 1849. It is exhibited at the Perkins Museum of Geology at the University of Vermont. Found at the time when knowledge of Earth's natural history was nascent, it proved key evidence for developing a glacial theory of New England. The whale skeleton was collected by Zadock Thompson and reconstructed by Albert David Hager in an unusual, anatomically incorrect manner. Later, that error was preserved for its historical significance. It was Vermont's official state fossil from 1993 to 2014, after which it became designated as Vermont's state marine fossil. Discovery and preservation The whale skeleton was uncovered in 1849, during the construction of the Rutland Railroad, Rutland & Burlington Railroad. The skeleton was found buried in a farmer's field, approximately below the surface. Initially, it was mistaken for a horse skeleton and part of the wha ...

Belugas
The beluga whale (/bɪˈluːɡə/) (Delphinapterus leucas) is an Arctic and sub-Arctic cetacean. It is one of two members of the family Monodontidae, along with the narwhal, and the only member of the genus Delphinapterus. It is also known as the white whale, as it is the only cetacean to regularly occur with this colour; the sea canary, due to its high-pitched calls; and the melonhead, though that more commonly refers to the melon-headed whale, which is an oceanic dolphin Animals *Beluga (sturgeon) *Beluga whale Vehicles *Airbus Beluga, a large transport airplane *Airbus BelugaXL, a larger transport airplane *Beluga-class submarine, a class of Russian SSA diesel-electric submarine *USS Beluga (SP-536), USS ''Beluga'' (SP-536), a United States Navy patrol boat Other uses *Beluga, Alaska *Beluga (restaurant) *Beluga caviar, roe of the beluga sturgeon * Beluga, a type of lentil *Beluga (vodka), a brand of Russian premium vodka * A Baby Beluga, a Serbia adoption festival See a ...

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

Paleontology In Vermont
Paleontology in Vermont comprises paleontological research occurring within or conducted by people from the U.S. state of Vermont. Fossils are generally uncommon in Vermont. Nevertheless, however, significant finds have been made in the state. Very few fossils are known in Vermont east of the Green Mountains due to the type of rock underlying that area. During the early part of the Paleozoic era, Vermont was covered by a warm, shallow sea that would end up being home to creatures like brachiopods, corals, crinoids, ostracoderms, and trilobites. There are no rocks in the state from the Carboniferous, Permian, Triassic, or Jurassic periods. The few Cretaceous rocks present contain no fossils. The Paleogene and Neogene periods are also absent from the local rock record. During the Ice Age, glaciers scoured the state. At times the state was inundated by seawater, allowing marine mammals to venture in. After the seawater drained away the state was home to mastodons. Local fossils ha ...

Fossils Of The United States
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Reverence (sculpture)
''Reverence'' is a sculpture in Vermont created by Jim Sardonis in 1989 that depicts two tails of whales "diving" into a sea of grass. It is meant to symbolize the fragility of the planet. The tails were made from 36 tons of African black granite and stand tall. The sculpture was commissioned by British metals trader David Threlkeld, who was then a resident of Randolph, Vermont. The tails were to be at the entrance to a conference center that Threlkeld was planning, but financing fell through and Threlkeld moved to Arizona. After ten years at this Randolph site, they were sold and then moved to Technology Park in South Burlington where Ben & Jerry's ice cream has its corporate headquarters. The ''Whale Tails'', as the sculpture is more commonly known by local residents, is a landmark on the side of Interstate 89 between exits 12 and 13, notable partly because Vermont is a landlocked state. The sculpture is located at , on the right side of the northbound lane. The sculpture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Isostatic Rebound
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ''ocean siphoning'' and ''continental levering'', the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.Milne, G.A., and J.X.

Laurentide Ice Sheet
The Laurentide Ice Sheet was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glacial epochs, from 2.58 million years ago to the present. The last advance covered most of northern North America between c. 95,000 and c. 20,000 years before the present day and, among other geomorphological effects, gouged out the five Great Lakes and the hosts of smaller lakes of the Canadian Shield. These lakes extend from the eastern Northwest Territories, through most of northern Canada, and the upper Midwestern United States (Minnesota, Wisconsin, and Michigan) to the Finger Lakes, through Lake Champlain and Lake George areas of New York, across the northern Appalachians into and through all of New England and Nova Scotia. At times, the ice sheet's southern margin included the present-day sites of coastal towns of the Northeastern United States, and cities such as Bos ...

Champlain Valley
The Champlain Valley is a region of the United States around Lake Champlain in Vermont and New York extending north slightly into Quebec, Canada. It is part of the St. Lawrence River drainage basin, drained northward by the Richelieu River into the St. Lawrence at Sorel-Tracy, Quebec (northeast of Montreal). The Richelieu valley is not generally referred to as part of the Champlain Valley. The Champlain Lake Valley is the most heavily populated region in Vermont, broadly stretching eastward from the lake's shore to the base of the Green Mountains. The state's largest city, Burlington, is located on the lake, and the city's associated suburban communities encompass part of the central section of the valley. Beyond urbanized Chittenden County, however, the valley's landscape is primarily open pasture and row crops, making the Champlain Valley the most productive agricultural region of Vermont. The New York portion of the Champlain Valley includes the eastern portions of Clinton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Champlain Sea
The Champlain Sea (french: Mer de Champlain) was a prehistoric inlet of the Atlantic Ocean into the North American continent, created by the retreating ice sheets during the closure of the last glacial period. The inlet once included lands in what are now the Canadian provinces of Quebec and Ontario, as well as parts of the American states of New York and Vermont. Origins The mass of ice from the continental ice sheets had depressed the rock beneath it over millennia. At the end of the last glacial period, while the rock was still depressed, the Saint Lawrence and Ottawa River valleys, as well as modern Lake Champlain, at that time the Lake Vermont, were below sea level and flooded with rising worldwide sea levels, once the ice no longer prevented the ocean from flowing into the region. As the land gradually rose again, in the process known as isostatic rebound, the sea coast gradually retreated to its current location. The sea lasted from about 13,000 years ago to about ...
