Monte Sano Mountain
Monte Sano Mountain is a mountain located in Huntsville, Alabama. The name ''Monte Sano'' is Spanish for "Mountain of health". This name comes from the fact that curative health resorts used to be located on the mountain to take advantage of the fresh air, clean water, and cooler temperatures. The top is relatively flat and lies just under 500 meters above sea level. This elevation is about 300 meters higher than the floor of the Tennessee River, Tennessee Valley, which surrounds it. A residential neighborhood occupies the western portion of the top. The eastern portion and slopes of the mountain are occupied by Monte Sano State Park. Monte Sano is connected to Round Top (Burritt) Mountain by a mountain pass, col to the south. Hotel Monte Sano & Railway The summer months in the late 1800s saw yellow fever, cholera and diphtheria in high proportions. Clean water and sanitary living conditions were found on the mountain and visitors' health improved. However, because the ...

Huntsville, Alabama
Huntsville is a city in Madison County, Limestone County, and Morgan County, Alabama, United States. It is the county seat of Madison County. Located in the Appalachian region of northern Alabama, Huntsville is the most populous city in the state. Huntsville was founded within the Mississippi Territory in 1805 and became an incorporated town in 1811. When Alabama was admitted as a state in 1819, Huntsville was designated for a year as the first capital, before that was moved to more central settlements. The city developed across nearby hills north of the Tennessee River, adding textile mills in the late nineteenth century. Its major growth has taken place since World War II. During the war, the Army established Redstone Arsenal near here with a chemical weapons plant, and nearby related facilities. After the war, additional research was conducted at Redstone Arsenal on rockets, followed by adaptations for space exploration. NASA's Marshall Space Flight Center, the Unit ...

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blevins Gap Nature Preserve
Blevins Gap Nature Preserve is a nature preserve in southern Huntsville, Alabama. It measures in total and contains over 12 miles of trails within its borders. Cecil Ashburn Drive splits the preserve into two parts. The northern section measures with 4.5 miles of trails, a rocky incline, and waterfalls. The southern portion measures the remaining and contains 8 miles of woodland trails. The trail system was designated as a National Recreation Trail in 2012. History The preserve contains the southernmost remnant of the "Spacewalk Trail", which was constructed by Boy Scouts in the 1960s and ran from Monte Sano State Park to the southern edge of Green Mountain. The northern portion of the preserve, donated in 1988, was the first piece of land ever donated to a land trust in Alabama. The Stevenson Trail and the Fanning Trail, both located within this northern portion, are named after the original donors.

Blastoid
Blastoids (class Blastoidea) are an extinct type of stemmed echinoderm, often referred to as sea buds. They first appear, along with many other echinoderm classes, in the Ordovician period, and reached their greatest diversity in the Mississippian subperiod of the Carboniferous period. However, blastoids may have originated in the Cambrian. Blastoids persisted until their extinction at the end of Permian, about 250 million years ago. Although never as diverse as their contemporary relatives, the crinoids, blastoids are common fossils, especially in many Mississippian-age rocks. Description Like most echinoderms, blastoids were protected by a set of interlocking plates of calcium carbonate, which formed the main body, or ''theca''. In life, the theca of a typical blastoid was attached to a stalk or column made up of stacked disc-shaped plates. The other end of the column was attached to the ocean floor by a holdfast, very much like stalked crinoids. The stalk was usually relat ...

Crinoid
Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have ...

Mississippian Age
The Mississippian ( , also known as Lower Carboniferous or Early Carboniferous) is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley. The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land. The cratons were surrounded by extensive delta systems and lagoons, and carbonate sedimentation on the surrounding continental platforms, covered by shallow seas. In North America, where the interval consists primarily of marine limestones, it is treate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pottsville Formation
The Pennsylvanian Pottsville Formation is a mapped bedrock unit in Pennsylvania, western Maryland, West Virginia, Ohio, and Alabama. It is a major ridge-former in the Ridge-and-Valley Appalachians of the eastern United States. The Pottsville Formation is conspicuous at many sites along the Allegheny Front, the eastern escarpment of the Allegheny or Appalachian Plateau. Description The Pottsville Formation consists of a gray conglomerate, fine to coarse grained sandstone, and is known to contain limestone, siltstone and shale, as well as anthracite and bituminous coal. It is considered a classic orogenic molasse. The formation was first described from a railroad cut south of Pottsville, Pennsylvania. Nomenclature and Stratigraphy The relationship to the term "Pottsville" and actual lithologic units is complex. Most fundamentally, the unit may be considered a Formation or a Group. As a Formation, the Pottsville may encompass the following members depending on the state in w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint River (Alabama)
The Flint River, long and draining an area of , is a tributary to the Tennessee River. The river rises in Lincoln County, Tennessee, and flows south into Madison County, Alabama, where most of the river's watershed (342 sq. mi.) is located. The land within this watershed is predominantly agricultural and has experienced significant recent residential growth from the city of Huntsville. The U.S. Geological Survey National Water-Quality Assessment Program is currently investigating water quality in the lower Tennessee River basin with several monitoring activities targeted in the Flint River Basin. Geology The Flint River rises on the southwestern fringe of the Cumberland Escarpment and primarily drains the plains that have been created by the erosion of this fringe of the Appalachians. Due to the sedimentary nature of this escarpment, which consists primarily of sandstone, star blue quartz can be found in small quantities in the stream bed because it easily survives weatheri ...
