A pedestal or plinth is the support of a statue or a vase. Although in Syria, Asia Minor and Tunisia the Romans raised the columns of their temples or propylaea on square pedestals, in Rome itself they were employed only to give greater importance to isolated columns, such as those of Trajan and Antoninus, or as a podium to the columns employed decoratively in the Roman triumphal arches; the architects of the Italian revival, conceived the idea that no order was complete without a pedestal, as the orders were by them employed to divide up and decorate a building in several stories, the cornice of the pedestal was carried through and formed the sills of their windows, or, in open arcades, round a court, the balustrade of the arcade. They would seem to have considered that the height of the pedestal should correspond in its proportion with that of the column or pilaster it supported. In the imperial China, a stone tortoise called bixi was traditionally used as the pedestal for important stele those associated with emperors.
According to the 1396 version of the regulations issued by the Ming Dynasty founder, the Hongwu Emperor, the highest nobility and the officials of the top 3 ranks were eligible for bixi-based funerary tablets, while lower-level mandarins' steles were to stand on simple rectangular pedestals. An elevated pedestal or plinth which bears a statue and, raised from the substructure supporting it is sometimes called an acropodium; the term is from the Greek akros or "topmost" and pous or "foot".

Colorado Springs, Colorado
Colorado Springs is a home rule municipality, the largest city by area in Colorado as well as the county seat and the most populous municipality of El Paso County, United States. Colorado Springs is located in the east central portion of the state, it is situated on Fountain Creek and is located 60 miles south of the Colorado State Capitol in Denver. At 6,035 feet the city stands over 1 mile above sea level, though some areas of the city are higher and lower. Colorado Springs is situated near the base of Pikes Peak, which rises 14,115 feet above sea level on the eastern edge of the Southern Rocky Mountains; the city is home to 24 national governing bodies of sport, including the United States Olympic Committee, the United States Olympic Training Center, USA Hockey. The city had an estimated population of 465,101 in 2016, a metro population of 712,000, ranking as the second most populous city in the state of Colorado, behind Denver, the 42nd most populous city in the United States; the Colorado Springs, CO Metropolitan Statistical Area had an estimated population of 712,327 in 2016.
The city is included in the Front Range Urban Corridor, an oblong region of urban population along the Front Range of the Rocky Mountains in Colorado and Wyoming following the path of Interstate 25 in both states. The city covers 194.9 square miles. In 2018, Colorado Springs received several accolades: U. S. News named Colorado Springs the number one most desirable place to live in the United States, number two on their list of the 125 Best Places to Live in the USA; the Metropolitan Policy Program at Brookings found that Colorado Springs was the fastest growing city for Millennials. Thumbtack's annual Small Business Friendliness Survey found Colorado Springs to be the number four most business friendly city in the country; the Ute and Cheyenne peoples were the first recorded inhabiting the area which would become Colorado Springs. Part of the territory included in the United States' 1803 Louisiana Purchase, the current city area was designated part of the 1854 Kansas Territory. In 1859, after the first local settlement was established, it became part of the Jefferson Territory on October 24 and of El Paso County on November 28.
Colorado City at the Front Range confluence of Fountain and Camp creeks was "formally organized on August 13, 1859" during the Pike's Peak Gold Rush. It served as the capital of the Colorado Territory from November 5, 1861, until August 14, 1862, when the capital was moved to Denver. In 1871 the Colorado Springs Company laid out the towns of La Font and Fountain Colony and downstream of Colorado City. Within a year, Fountain Colony would be renamed "Colorado Springs", was incorporated; the El Paso County seat shifted from Colorado City in 1873 to the Town of Colorado Springs. On December 1, 1880, Colorado Springs expanded northward with two annexations; the second period of annexations was during 1889–90, included Seavey's Addition, West Colorado Springs, East End, another North End addition. In 1891 the Broadmoor Land Company built the Broadmoor suburb, which included the Broadmoor Casino, by December 12, 1895, the city had "four Mining Exchanges and 275 mining brokers." By 1898, the city was designated into quadrants by the north-south Cascade Avenue and the east-west Washington/Pike's Peak avenues.
From 1899 to 1901 Tesla Experimental Station operated on Knob Hill, aircraft flights to the Broadmoor's neighboring fields began in 1919. Alexander Airport north of the city opened in 1925, in 1927 the original Colorado Springs Municipal Airport land was purchased east of the city. In World War II the United States Army Air Forces leased land adjacent to the municipal airfield, naming it "Peterson Field" in December 1942; this was only one of several military presences around Colorado Springs during the war. In November 1950, Ent Air Force Base was selected as the Cold War headquarters for Air Defense Command; the former WWII Army Air Base, Peterson Field, inactivated at the end of the war, was re-opened in 1951 as a U. S. Air Force base; the 1950s through 1970s saw a continued expansion of the military presence in the area, with the establishment of NORAD's headquarters in the city, as well as the ADCOM headquarters. Between 1965 and 1968, the University of Colorado Colorado Springs, Pikes Peak Community College and Colorado Technical University were established in or near the city.
In 1977 most of the former Ent AFB became a US Olympic training center. The Libertarian Party was founded within the city in the 1970s. On October 1, 1981, the Broadmoor Addition, Cheyenne Canon, Ivywild and Stratton Meadows were annexed after the Colorado Supreme Court "overturned a district court decision that voided the annexation". Further annexations expanding the city include the Nielson Addition and Vineyard Commerce Park Annexation in September 2008; the city lies in a high desert with the Southern Rocky Mountains to the west, the Palmer Divide to the north, high plains further east, high desert lands to the south when leaving Fountain and approaching Pueblo. According to the United States Census Bureau, the city has a total area of 194.6 square miles, of which 194.6 square miles is land and 0.35 square miles, or 0.19%, is water. Colorado Springs has many features of a modern urban area, such as parks, bike trails, urban open-area spaces. However, it is not exempt from problems that plague cities that experience tremendous growth, such as overcrowded roads and highways, crime and government budget issues.
Many of the problems are indirec
Road debris, a form of road hazard, is debris on or off a road. Road debris includes substances and objects that are foreign to the normal roadway environment. Debris may be produced by vehicular or nonvehicular sources, but in all cases it is considered litter, a form of solid waste. Debris may tend to collect in areas where vehicles do not drive, such as on the edges, around traffic islands, junctions. Road spray or tire kickup is road debris, kicked up, pushed out, or sprayed out from a tire. In 2004, a AAA Foundation for Traffic Safety study revealed that vehicle-related road debris caused 25,000 accidents and nearly 100 deaths a year. Road debris can be caused by various factors, including objects falling off vehicles or natural disasters and weather wind, tornadoes, etc. Examples of road debris include: Particulates, dirt and mud Asphalt, pebbles, rocks/stones/boulders, etc. Particles of road salt and other de-icers Litter, furniture and other garbage/trash/waste Glass, nails and other sharp objects Auto parts, tire tread, etc.
Bicycles, roof racks, lumber, construction supplies, pallets and other items dropped from moving vehicles deliberately or accidentally Animal corpses Broken glass and other materials that fall off vehicles during traffic collisions Ice, snow and other liquids like grease and engine oil Plants and their parts: branches, sticks, seeds etc. Road debris is a hazard that can cause loss of vehicle control with damages ranging from a flat tire, vehicular rollover, penetration of the passenger compartment by the debris, or collision, with accompanying injuries or deaths. In the year 2011, the National Highway Traffic Safety Administration's Traffic Safety Facts found that more than 800 persons were killed across America by "non-fixed objects". California had the highest number of total deaths for any state, while New Mexico had the greatest probability for death from a vehicle-debris crash in that year. In 2004, a AAA Foundation for Traffic Safety study revealed that vehicle-related road debris caused 25,000 accidents—and nearly 100 deaths—each year.
At highway speeds small debris can be deadly. On June 16, 1925, in the United States, a passenger train carrying German and American tourists from Chicago, Illinois to Hoboken, New Jersey struck debris washed into a road crossing and derailed during a heavy thunderstorm. Collision with road debris resulted in a solar vehicle accident at the World Solar Challenge 2007 in Australia. Road debris, for the most part, tends to collect in areas where two-track vehicles such as cars and buses do not drive. In urban areas, this tends to be on the edges and on the crown of the road, debris collects around traffic islands and junctions. In rural areas, debris collects on the outside of corners and bends. Road debris can be dangerous to bicyclists, who may have to travel outside the cycle lane and into traffic to avoid debris. Flooding can occur if storm drains and street gutters are not kept clear of road debris and litter. Large quantities of water are sometimes thrown up from the road by large vehicles, creating visibility problems for the drivers of oncoming, nearby, or following vehicles.
Following vehicles may reduce the problem by slowing and increasing the following/separation distance. Headlights improve vehicle visibility for all drivers, including those dealing with the spray. Driving manuals advise against following vehicles too in these hazardous conditions. Road spray can cause reduced visibility and reduce the safety of motorists. Over time, road spray and gunk from brake pads coat the rim of the wheel, interfering with braking power. In motorsport racing, road debris can cause loss of subsequent crashes; the yellow caution flag is used to indicate a track hazard, the pace/safety car will come out. Road debris can cause other more specific problems and damage to vehicles. Rocks striking the catalytic converter can cause the internal mat to clog the converter. Several recalls have occurred due to road debris; the 2005 Scion TC's wind deflector was recalled because of potential shatter from road debris impact. The 2004 Mitsubishi Endeavor was recalled in February 2010 when it was determined that a mixture of road salt and road debris might be trapped between a reinforcing bracket and the fuel filler pipe, causing corrosion.
The 2001 Chevrolet C/K chassis cab truck was recalled on discovery that road debris could strike and damage its pressure relief valves. Small debris particles and dust constitute a significant problem when they are washed into the soil and leak into groundwater reservoirs through surface runoff urban runoff. Roadside soil and water contamination can result when the concentration of harmful constituents is high enough; the greater the surface area of synthetic rubber waste fragments, the greater the potential for breakdown into harmful constituents. For leached tire debris, the potential environmental impact of the ingredients zinc and organic toxicants has been demonstrated. A car bra can help reduce damage from minor road debris. Road spray is lessened on stone mastic asphalt and open-graded asphalt and can be further reduced with fenders and/or mud flaps. Street sweepers and winter service vehicles remove most solid road debris and the Adopt a Highway program helps. Road si
Australia the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area; the neighbouring countries are Papua New Guinea and East Timor to the north. The population of 25 million is urbanised and concentrated on the eastern seaboard. Australia's capital is Canberra, its largest city is Sydney; the country's other major metropolitan areas are Melbourne, Brisbane and Adelaide. Australia was inhabited by indigenous Australians for about 60,000 years before the first British settlement in the late 18th century, it is documented. After the European exploration of the continent by Dutch explorers in 1606, who named it New Holland, Australia's eastern half was claimed by Great Britain in 1770 and settled through penal transportation to the colony of New South Wales from 26 January 1788, a date which became Australia's national day; the population grew in subsequent decades, by the 1850s most of the continent had been explored and an additional five self-governing crown colonies established.
On 1 January 1901, the six colonies federated. Australia has since maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy, comprising six states and ten territories. Being the oldest and driest inhabited continent, with the least fertile soils, Australia has a landmass of 7,617,930 square kilometres. A megadiverse country, its size gives it a wide variety of landscapes, with deserts in the centre, tropical rainforests in the north-east and mountain ranges in the south-east. A gold rush began in Australia in the early 1850s, its population density, 2.8 inhabitants per square kilometre, remains among the lowest in the world. Australia generates its income from various sources including mining-related exports, telecommunications and manufacturing. Indigenous Australian rock art is the oldest and richest in the world, dating as far back as 60,000 years and spread across hundreds of thousands of sites. Australia is a developed country, with the world's 14th-largest economy.
It has a high-income economy, with the world's tenth-highest per capita income. It is a regional power, has the world's 13th-highest military expenditure. Australia has the world's ninth-largest immigrant population, with immigrants accounting for 26% of the population. Having the third-highest human development index and the eighth-highest ranked democracy globally, the country ranks in quality of life, education, economic freedom, civil liberties and political rights, with all its major cities faring well in global comparative livability surveys. Australia is a member of the United Nations, G20, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development, World Trade Organization, Asia-Pacific Economic Cooperation, Pacific Islands Forum and the ASEAN Plus Six mechanism; the name Australia is derived from the Latin Terra Australis, a name used for a hypothetical continent in the Southern Hemisphere since ancient times. When Europeans first began visiting and mapping Australia in the 17th century, the name Terra Australis was applied to the new territories.
Until the early 19th century, Australia was best known as "New Holland", a name first applied by the Dutch explorer Abel Tasman in 1644 and subsequently anglicised. Terra Australis still saw occasional usage, such as in scientific texts; the name Australia was popularised by the explorer Matthew Flinders, who said it was "more agreeable to the ear, an assimilation to the names of the other great portions of the earth". The first time that Australia appears to have been used was in April 1817, when Governor Lachlan Macquarie acknowledged the receipt of Flinders' charts of Australia from Lord Bathurst. In December 1817, Macquarie recommended to the Colonial Office. In 1824, the Admiralty agreed that the continent should be known by that name; the first official published use of the new name came with the publication in 1830 of The Australia Directory by the Hydrographic Office. Colloquial names for Australia include "Oz" and "the Land Down Under". Other epithets include "the Great Southern Land", "the Lucky Country", "the Sunburnt Country", "the Wide Brown Land".
The latter two both derive from Dorothea Mackellar's 1908 poem "My Country". Human habitation of the Australian continent is estimated to have begun around 65,000 to 70,000 years ago, with the migration of people by land bridges and short sea-crossings from what is now Southeast Asia; these first inhabitants were the ancestors of modern Indigenous Australians. Aboriginal Australian culture is one of the oldest continual civilisations on earth. At the time of first European contact, most Indigenous Australians were hunter-gatherers with complex economies and societies. Recent archaeological finds suggest. Indigenous Australians have an oral culture with spiritual values based on reverence for the land and a belief in the Dreamtime; the Torres Strait Islanders, ethnically Melanesian, obtained their livelihood from seasonal horticulture and the resources of their reefs and seas. The northern coasts and waters of Australia were visited s
The Horeke basalts is a disused formation that contained Miocene-Pliocene basalt lava flows that covered a large area in central Northland Region of New Zealand, in places forms a high plateau around Okaihau. Wairere Boulders is a nature park providing walkways through boulders of basalt, derived by erosion of one of these older basalt flows that used to be included in the Horeke Basalt and are now included in the Kerikeri Volcanic Group; the boulders in the Wairere valley are the erosional remnants of a lava flow out of a volcano near Lake Omapere, dated as 2.8 million years old. There are the other at 2.67 million years. There is a slight difference in chemistry in the two rocks that have been dated suggesting that the eruption took the form of several flows that once blanketed the high ground to the east of Horeke. Erosion of the clay underlay of the basalt plateau started to create a v-valley; the edges of the cap broke off. These blocks travelled downwards along the hill sides towards the bottom of the valley, where they accumulated.
They fill now a portion of the valley, about 1.4 km long and up to 350 m wide. Some of the channels discovered in the basalt are 1000 mm deep and up to 300 mm wide, unusual for basalts, it is the result of chemical leaching by acidic seepage from the humus on top of the boulders
New Zealand is a sovereign island country in the southwestern Pacific Ocean. The country geographically comprises two main landmasses—the North Island, the South Island —and around 600 smaller islands. New Zealand is situated some 2,000 kilometres east of Australia across the Tasman Sea and 1,000 kilometres south of the Pacific island areas of New Caledonia and Tonga; because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal and plant life; the country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington. Sometime between 1250 and 1300, Polynesians settled in the islands that were named New Zealand and developed a distinctive Māori culture. In 1642, Dutch explorer Abel Tasman became the first European to sight New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs signed the Treaty of Waitangi, which declared British sovereignty over the islands.
In 1841, New Zealand became a colony within the British Empire and in 1907 it became a dominion. Today, the majority of New Zealand's population of 4.9 million is of European descent. Reflecting this, New Zealand's culture is derived from Māori and early British settlers, with recent broadening arising from increased immigration; the official languages are English, Māori, NZ Sign Language, with English being dominant. A developed country, New Zealand ranks in international comparisons of national performance, such as quality of life, education, protection of civil liberties, economic freedom. New Zealand underwent major economic changes during the 1980s, which transformed it from a protectionist to a liberalised free-trade economy; the service sector dominates the national economy, followed by the industrial sector, agriculture. Nationally, legislative authority is vested in an elected, unicameral Parliament, while executive political power is exercised by the Cabinet, led by the prime minister Jacinda Ardern.
Queen Elizabeth II is the country's monarch and is represented by a governor-general Dame Patsy Reddy. In addition, New Zealand is organised into 11 regional councils and 67 territorial authorities for local government purposes; the Realm of New Zealand includes Tokelau. New Zealand is a member of the United Nations, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development, ASEAN Plus Six, Asia-Pacific Economic Cooperation, the Pacific Community and the Pacific Islands Forum. Dutch explorer Abel Tasman sighted New Zealand in 1642 and named it Staten Land "in honour of the States General", he wrote, "it is possible that this land joins to the Staten Land but it is uncertain", referring to a landmass of the same name at the southern tip of South America, discovered by Jacob Le Maire in 1616. In 1645, Dutch cartographers renamed the land Nova Zeelandia after the Dutch province of Zeeland. British explorer James Cook subsequently anglicised the name to New Zealand. Aotearoa is the current Māori name for New Zealand.
It is unknown whether Māori had a name for the whole country before the arrival of Europeans, with Aotearoa referring to just the North Island. Māori had several traditional names for the two main islands, including Te Ika-a-Māui for the North Island and Te Waipounamu or Te Waka o Aoraki for the South Island. Early European maps labelled the islands North and South. In 1830, maps began to use North and South to distinguish the two largest islands and by 1907 this was the accepted norm; the New Zealand Geographic Board discovered in 2009 that the names of the North Island and South Island had never been formalised, names and alternative names were formalised in 2013. This set the names as North Island or Te Ika-a-Māui, South Island or Te Waipounamu. For each island, either its English or Māori name can be used. New Zealand was one of the last major landmasses settled by humans. Radiocarbon dating, evidence of deforestation and mitochondrial DNA variability within Māori populations suggest New Zealand was first settled by Eastern Polynesians between 1250 and 1300, concluding a long series of voyages through the southern Pacific islands.
Over the centuries that followed, these settlers developed a distinct culture now known as Māori. The population was divided into iwi and hapū who would sometimes cooperate, sometimes compete and sometimes fight against each other. At some point a group of Māori migrated to Rēkohu, now known as the Chatham Islands, where they developed their distinct Moriori culture; the Moriori population was all but wiped out between 1835 and 1862 because of Taranaki Māori invasion and enslavement in the 1830s, although European diseases contributed. In 1862 only 101 survived, the last known full-blooded Moriori died in 1933; the first Europeans known to have reached New Zeala
The Devonian is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, 419.2 million years ago, to the beginning of the Carboniferous, 358.9 Mya. It is named after Devon, where rocks from this period were first studied; the first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, by the end of the period the first seed-bearing plants appeared. Various terrestrial arthropods became well-established. Fish reached substantial diversity during this time, leading the Devonian to be dubbed the "Age of Fishes." The first ray-finned and lobe-finned bony fish appeared, while the placoderms began dominating every known aquatic environment. The ancestors of all four-limbed vertebrates began adapting to walking on land, as their strong pectoral and pelvic fins evolved into legs.
In the oceans, primitive sharks became more numerous than in the Late Ordovician. The first ammonites, species of molluscs, appeared. Trilobites, the mollusc-like brachiopods and the great coral reefs, were still common; the Late Devonian extinction which started about 375 million years ago affected marine life, killing off all placodermi, all trilobites, save for a few species of the order Proetida. The palaeogeography was dominated by the supercontinent of Gondwana to the south, the continent of Siberia to the north, the early formation of the small continent of Euramerica in between; the period is named after Devon, a county in southwestern England, where a controversial argument in the 1830s over the age and structure of the rocks found distributed throughout the county was resolved by the definition of the Devonian period in the geological timescale. The Great Devonian Controversy was a long period of vigorous argument and counter-argument between the main protagonists of Roderick Murchison with Adam Sedgwick against Henry De la Beche supported by George Bellas Greenough.
Murchison and Sedgwick named the period they proposed as the Devonian System. While the rock beds that define the start and end of the Devonian period are well identified, the exact dates are uncertain. According to the International Commission on Stratigraphy, the Devonian extends from the end of the Silurian 419.2 Mya, to the beginning of the Carboniferous 358.9 Mya. In nineteenth-century texts the Devonian has been called the "Old Red Age", after the red and brown terrestrial deposits known in the United Kingdom as the Old Red Sandstone in which early fossil discoveries were found. Another common term is "Age of the Fishes", referring to the evolution of several major groups of fish that took place during the period. Older literature on the Anglo-Welsh basin divides it into the Downtonian, Dittonian and Farlovian stages, the latter three of which are placed in the Devonian; the Devonian has erroneously been characterised as a "greenhouse age", due to sampling bias: most of the early Devonian-age discoveries came from the strata of western Europe and eastern North America, which at the time straddled the Equator as part of the supercontinent of Euramerica where fossil signatures of widespread reefs indicate tropical climates that were warm and moderately humid but in fact the climate in the Devonian differed during its epochs and between geographic regions.
For example, during the Early Devonian, arid conditions were prevalent through much of the world including Siberia, North America, China, but Africa and South America had a warm temperate climate. In the Late Devonian, by contrast, arid conditions were less prevalent across the world and temperate climates were more common; the Devonian Period is formally broken into Early and Late subdivisions. The rocks corresponding to those epochs are referred to as belonging to the Lower and Upper parts of the Devonian System. Early DevonianThe Early Devonian lasted from 419.2 ± 2.8 to 393.3 ± 2.5 and began with the Lochkovian stage, which lasted until the Pragian. It spanned from 410.8 ± 2.8 to 407.6 ± 2.5, was followed by the Emsian, which lasted until the Middle Devonian began, 393.3± 2.7 million years ago. During this time, the first ammonoids appeared. Ammonoids during this time period differed little from their nautiloid counterparts; these ammonoids belong to the order Agoniatitida, which in epochs evolved to new ammonoid orders, for example Goniatitida and Clymeniida.
This class of cephalopod molluscs would dominate the marine fauna until the beginning of the Mesozoic era. Middle DevonianThe Middle Devonian comprised two subdivisions: first the Eifelian, which gave way to the Givetian 387.7± 2.7 million years ago. During this time the jawless agnathan fishes began to decline in diversity in freshwater and marine environments due to drastic environmental changes and due to the increasing competition and diversity of jawed fishes; the shallow, oxygen-depleted waters of Devonian inland lakes, surrounded by primitive plants, provided the environment necessary for certain early fish to develop such essential characteristics as well developed lungs, the ability to crawl out of the water and onto the land for short periods of time. Late DevonianFinally, the Late Devonian started with the Frasnian, 382.7 ± 2.8 to 372.2 ± 2.5, during which the first forests took shape on land. The first tetrapods appeared in the fossil record in the ensuing Famennian subdivisi
