66-841: The Okefenokee Swamp is a shallow, 438,000-acre (177,000 ha), peat -filled wetland straddling the Georgia – Florida line in the United States. A majority of the swamp is protected by the Okefenokee National Wildlife Refuge and the Okefenokee Wilderness . The Okefenokee Swamp is considered to be one of the Seven Natural Wonders of Georgia and is the largest " blackwater " swamp in North America. The swamp

132-477: A 1920s logging town of 600 residents. Most of the Okefenokee Swamp is included in the 403,000-acre (163,000 ha) Okefenokee National Wildlife Refuge . The largest wildfire in the swamp's history began with a lightning strike near the center of the refuge on May 5, 2007, eventually merging with another wildfire that began near Waycross, Georgia , on April 16 when a tree fell on a power line. Named

198-506: A form of erosion that occur at the sides of gullies that cut into the peat; they sometimes also occur in isolation. Hags may result when flowing water cuts downwards into the peat and when fire or overgrazing exposes the peat surface. Once the peat is exposed in these ways, it is prone to further erosion by wind, water and livestock. The result is overhanging vegetation and peat. Hags are too steep and unstable for vegetation to establish itself, so they continue to erode unless restorative action

264-496: A result of peat drainage, the organic carbon—which built over thousands of years and is normally underwater—is suddenly exposed to the air. It decomposes and turns into carbon dioxide (CO 2 ), which is released into the atmosphere. The global CO 2 emissions from drained peatlands have increased from 1,058 Mton in 1990 to 1,298 Mton in 2008 (a 20% increase). This increase has particularly taken place in developing countries, of which Indonesia , Malaysia and Papua New Guinea are

330-490: A small increase in carbon dioxide uptake, meaning that it contributes to the permafrost carbon feedback . Under 2 °C global warming , 0.7 million km of peatland permafrost could thaw, and with warming of +1.5 to 6 °C a cumulative 0.7 to 3 PgC of methane could be released as a result of permafrost peatland thaw by 2100. The forcing from these potential emissions would be approximately equivalent to 1% of projected anthropogenic emissions. One characteristic of peat

396-539: A tenth of the total permafrost area, and also a tenth (185 ± 66 Gt) of all permafrost carbon, equivalent to around half of the carbon stored in the atmosphere. Dry peat is a good insulator (with a thermal conductivity of around 0.25 Wm K ) and therefore plays an important role in protecting permafrost from thaw. The insulating effect of dry peat also makes it integral to unique permafrost landforms such as palsas and permafrost peat plateaus. Peatland permafrost thaw tends to result in an increase in methane emissions and

462-516: Is a common practice to forest used peat bogs instead of giving them a chance to renew. This leads to lower levels of CO 2 storage than the original peat bog. Council, Georgia Council is an unincorporated community in Clinch County , in the U.S. state of Georgia . A post office called Council was established in 1909, and remained in operation until 1958. The community was named after C. C. and John M. Council, proprietors of

528-487: Is also reported that peat regrowth takes place only in 30–40% of peatlands. Centuries of burning and draining of peat by humans has released a significant amount of CO 2 into the atmosphere, and much peatland restoration is needed to help limit climate change . Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses , sedges and shrubs. As it accumulates,

594-477: Is available in considerable quantities. It is burned to produce heat and electricity . Peat provides around 4% of Finland's annual energy production. Also, agricultural and forestry-drained peat bogs actively release more CO 2 annually than is released in peat energy production in Finland. The average regrowth rate of a single peat bog, however, is indeed slow, from 1,000 up to 5,000 years. Furthermore, it

660-551: Is cut by hand and left to dry in the sun. In many countries, including Ireland and Scotland , peat was traditionally stacked to dry in rural areas and used for cooking and domestic heating. This tradition can be traced back to the Roman period. For industrial uses, companies may use pressure to extract water from the peat, which is soft and easily compressed. In Sweden, farmers use dried peat to absorb excrement from cattle that are wintered indoors. The most essential property of peat

726-423: Is either fibric, hemic, or sapric. Fibric peats are the least decomposed and consist of intact fibre. Hemic peats are partially decomposed and sapric are the most decomposed. Phragmites peat are composed of reed grass, Phragmites australis , and other grasses. It is denser than many other types of peat. Engineers may describe a soil as peat which has a relatively high percentage of organic material. This soil

792-712: Is estimated that in 1997, peat and forest fires in Indonesia released between 0.81 and 2.57 gigatonnes (0.89 and 2.83 billion short tons; 0.80 and 2.53 billion long tons) of carbon; equivalent to 13–40 percent of the amount released by global fossil fuel burning, and greater than the carbon uptake of the world's biosphere. These fires may be responsible for the acceleration in the increase in carbon dioxide levels since 1998. More than 100 peat fires in Kalimantan and East Sumatra have continued to burn since 1997; each year, these peat fires ignite new forest fires above

858-520: Is famous for its amphibians and reptiles such as toads , frogs , turtles , lizards , snakes , and an abundance of American alligators . The oldest known alligator, named "Okefenokee Joe" after environmentalist Okefenokee Joe , died in September 2021, at almost 80 years of age. The Okefenokee Swamp is also a critical habitat for the Florida black bear . More than 600,000 acres (240,000 ha) of

924-483: Is problematic because it exhibits poor consolidation properties—it cannot be easily compacted to serve as a stable foundation to support loads, such as roads or buildings. In a widely cited article, Joosten and Clarke (2002) described peatlands or mires (which they say are the same) as the most widespread of all wetland types in the world, representing 50 to 70% of global wetlands. They cover over 4 million square kilometres [1.5 million square miles] or 3% of

990-506: Is retaining moisture in container soil when it is dry while preventing the excess water from killing roots when it is wet. Peat can store nutrients although it is not fertile itself—it is polyelectrolytic with a high ion-exchange capacity due to its oxidized lignin. Peat is discouraged as a soil amendment by the Royal Botanic Gardens, Kew , England, since 2003. While bark or coir -based peat-free potting soil mixes are on

1056-635: Is sometimes used in freshwater aquaria . It is seen most commonly in soft water or blackwater river systems such as those mimicking the Amazon River basin. In addition to being soft and therefore suitable for demersal (bottom-dwelling) species such as Corydoras catfish, peat is reported to have many other beneficial functions in freshwater aquaria. It softens water by acting as an ion exchanger ; it also contains substances that are beneficial for plants and fishes' reproductive health. Peat can prevent algae growth and kill microorganisms. Peat often stains

1122-769: Is taken. In June 2002, the United Nations Development Programme launched the Wetlands Ecosystem and Tropical Peat Swamp Forest Rehabilitation Project. This project was targeted to last for five years, and brings together the efforts of various non-government organisations. In November 2002, the International Peatland (formerly Peat) Society (IPS) and the International Mire Conservation Group (IMCG) published guidelines on

1188-565: Is the average depth of the boreal [northern] peatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO 2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon , which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. Peat is not a renewable source of energy , due to its extraction rate in industrialized countries far exceeding its slow regrowth rate of 1 mm (0.04 in) per year, and as it

1254-401: Is the bioaccumulation of metals concentrated in the peat. Accumulated mercury is of significant environmental concern. Large areas of organic wetland (peat) soils are currently drained for agriculture, forestry and peat extraction (i.e. through canals ). This process is taking place all over the world. This not only destroys the habitat of many species but also heavily fuels climate change. As

1320-407: Is the most efficient carbon sink on the planet , because peatland plants capture carbon dioxide (CO 2 ) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [4.9 to 7.5 ft], which

1452-537: The Bugaboo Scrub Fire , by May 31, it had burned more than 600,000 acres (240,000 ha), or more than 935 square miles, and remains the largest wildfire in both Georgia and Florida history. In 2011, the Honey Prairie Fire consumed 309,200 acres (125,100 ha) of land in the swamp. There are four public entrances: In addition, a 501(c)(3) non-profit, Okefenokee Swamp Park , provides

1518-819: The Falkland Islands and Indonesia ( Kalimantan [Sungai Putri, Danau Siawan, Sungai Tolak], Rasau Jaya ( West Kalimantan ) and Sumatra ). Indonesia has more tropical peatlands and mangrove forests than any other nation on earth, but Indonesia is losing wetlands by 100,000 hectares (250,000 acres) per year. A catalog of the peat research collection at the University of Minnesota Duluth provides references to research on worldwide peat and peatlands. About 7% of all peatlands have been exploited for agriculture and forestry . Under certain conditions, peat will turn into lignite coal over geologic periods of time. Peat can be used as fuel once dried. Traditionally, peat

1584-486: The Okefenokee National Wildlife Refuge each year. The swamp provides an important economic resource to southeast Georgia and northeast Florida. More than 600,000 visitors from as many as 46 countries travel to the Okefenokee refuge each year to enjoy its unmatched wilderness. This tourism supports over 750 local jobs and contributes over $ 64 million to local economies. A 50-year titanium mining operation by DuPont

1650-593: The Timucua -speaking Oconi , who dwelt in or on the margin of the swamp. The Spanish friars built the mission of Santiago de Oconi in order to convert them to Christianity. The Oconi's boating skills, developed in the hazardous swamps, likely contributed to their later employment by the Spanish as ferrymen across the St. Johns River , near the riverside terminus of North Florida's camino real. Modern-day longtime residents of

1716-996: The West Siberian Lowland , the Hudson Bay Lowlands and the Mackenzie River Valley. There is less peat in the Southern Hemisphere, in part because there is less land. The world's largest tropical peatland is located in Africa (the Democratic Republic of Congo). In addition, the vast Magellanic Moorland in South America (Southern Patagonia / Tierra del Fuego ) is an extensive peat-dominated landscape. Peat can be found in New Zealand , Kerguelen ,

1782-597: The tanning properties of the acidic water, as well as by the antibiotic properties of the organic component sphagnan. A famous example is the Tollund Man in Denmark. Having been discovered in 1950 after being mistaken for a recent murder victim, he was exhumed for scientific purposes and dated to have lived during the 4th century BC. Before that, another bog body, the Elling Woman , had been discovered in 1938 in

1848-474: The 438,000-acre (177,000 ha) Okefenokee, sending volumes of smoke across the southern Atlantic seaboard and with an unknown impact on wildlife. With the drought still continuing, the massive Honey Prairie fire continued to burn at only 75% containment. On April 17, 2012, the Honey Prairie Fire was finally declared out. Thousands of firefighters, refuge neighbors, and businesses contributed to

1914-559: The Okefenokee Refuge. However, in 2022, U.S. Senator Jon Ossoff blocked the proposed titanium mine after the U.S. Fish and Wildlife Service warned of severe potential damage to the wildlife refuge. The Okefenokee Swamp was listed as one of America's Most Endangered Rivers in 2020 and again in 2023 on account of the mining threats. The Okefenokee Swamp is part of the Southeastern conifer forests ecoregion . Much of

1980-475: The Okefenokee Swamp, referred to as "Swampers", are of overwhelmingly English ancestry . Due to relative isolation, the inhabitants of the Okefenokee used Elizabethan phrases and syntax, preserved since the early colonial period when such speech was common in England, well into the 20th century. The Suwannee Canal was dug across the swamp in the late 19th century in a failed attempt to drain the Okefenokee. After

2046-538: The Okefenokee is a southern coastal plain nonriverine basin swamp , forested by bald cypress ( Taxodium distichum ) and swamp tupelo ( Nyssa biflora ) trees. Upland areas support southern coastal plain oak domes and hammocks , thick stands of evergreen oaks . Drier and more frequently burned areas support Atlantic coastal plain upland longleaf pine woodlands of longleaf pine ( Pinus palustris ). The swamp has many species of carnivorous plants , including many species of Utricularia , Sarracenia psittacina , and

2112-572: The Okefenokee region burned from April to July 2007. Essentially the entire swamp burned, but the degrees of impact are widely varied. Smoke from the fires was reported as far away as Atlanta and Orlando . Four years later, in April 2011, the Honey Prairie wildfire began when the swamp was left much drier than usual by an extreme drought . As of January 2012, the Honey Prairie fire had already scorched more than 315,000 acres (127,000 ha) of

2178-539: The Suwannee Canal Company's bankruptcy, most of the swamp was purchased by the Hebard family of Philadelphia, who conducted extensive cypress logging operations from 1909 to 1927. Several other logging companies ran railroad lines into the swamp until 1942; some remnants remain visible crossing swamp waterways. On the west side of the swamp, at Billy's Island, logging equipment and other artifacts remain of

2244-548: The West Siberian peatland. Palsa mires have a rich bird life and are an EU-red listed habitat, and in Canada riparian peat banks are used as maternity sites for polar bears. Natural peatlands also have many species of wild orchids and carnivorous plants. For more on biological communities, see wetland , bog or fen . Around half of the area of northern peatlands is permafrost -affected, and this area represents around

2310-522: The bogland remains constantly wet which helps promote peat production. Most modern peat bogs formed 12,000 years ago in high latitudes after the glaciers retreated at the end of the last ice age . Peat usually accumulates slowly at the rate of about a millimetre per year. The estimated carbon content is 415 gigatonnes (457 billion short tons) (northern peatlands), 50 Gt (55 billion short tons) ( tropical peatlands ) and 15 Gt (17 billion short tons) (South America). Peat material

2376-820: The boundaries of the 402,000 acre Okefenokee National Wildlife Refuge, with only 18,206 acres (7,368 ha) burned outside the refuge. On April 6, 2017, a lightning strike started the West Mims Fire, which burned about 152,000 acres (62,000 ha). Peat Peatlands, particularly bogs , are the primary source of peat; although less common, other wetlands, including fens , pocosins and peat swamp forests , also deposit peat. Landscapes covered in peat are home to specific kinds of plants, including Sphagnum moss, ericaceous shrubs and sedges . Because organic matter accumulates over thousands of years, peat deposits provide records of past vegetation and climate by preserving plant remains, such as pollen. This allows

2442-550: The capital of Moscow with a toxic smoke blanket . The situation remained critical until the end of August 2010. In June 2019, despite some forest fire prevention methods being put in place, peat fires in the Arctic emitted 50 megatonnes (55 million short tons; 49 million long tons) of CO 2 , which is equal to Sweden's total annual emissions. The peat fires are linked to climate change, as they are much more likely to occur nowadays due to this effect. Peat "hags" are

2508-428: The concept of peat archives, a phrase coined by influential peatland scientist Harry Godwin in 1981. In a peat profile there is a fossilized record of changes over time in the vegetation, pollen, spores, animals (from microscopic to the giant elk), and archaeological remains that have been deposited in place, as well as pollen, spores and particles brought in by wind and weather. These remains are collectively termed

2574-489: The edge of an ancient Atlantic coastal terrace, the geological relic of a Pleistocene estuary. The swamp is bordered by Trail Ridge, a strip of elevated land believed to have formed as coastal dunes or an offshore barrier island. The St. Marys River and the Suwannee River both originate in the swamp. The Suwannee River originates as stream channels in the heart of the Okefenokee Swamp and drains at least 90 percent of

2640-455: The fastest-growing top emitters. This estimate excludes emissions from peat fires (conservative estimates amount to at least 4,000 Mton/CO 2 -eq./yr for south-east Asia). With 174 Mton/CO 2 -eq./yr, the EU is after Indonesia (500 Mton) and before Russia (161 Mton), the world's second-largest emitter of drainage-related peatland CO 2 (excl. extracted peat and fires). Total CO 2 emissions from

2772-603: The ground. In North America, peat fires can occur during severe droughts throughout their occurrence, from boreal forests in Canada to swamps and fens in the subtropical southern Florida Everglades . Once a fire has burnt through the area, hollows in the peat are burnt out, and hummocks are desiccated but can contribute to Sphagnum recolonization. In the summer of 2010, an unusually high heat wave of up to 40 °C (104 °F) ignited large deposits of peat in Central Russia, burning thousands of houses and covering

2838-604: The land and freshwater surface of the planet. In these ecosystems are found one third of the world's soil carbon and 10% of global freshwater resources. These ecosystems are characterized by the unique ability to accumulate and store dead organic matter from Sphagnum and many other non-moss species, as peat, under conditions of almost permanent water saturation. Peatlands are adapted to the extreme conditions of high water and low oxygen content, of toxic elements and low availability of plant nutrients. Their water chemistry varies from alkaline to acidic. Peatlands occur on all continents, from

2904-509: The main source of water for large cities, including Dublin. Peat wetlands also used to have a degree of metallurgical importance in the Early Middle Ages , being the primary source of bog iron used to create swords and armour. Many peat swamps along the coast of Malaysia serve as a natural means of flood mitigation, with any overflow being absorbed by the peat, provided forests are still present to prevent peat fires. Peat

2970-552: The northernmost access into the Okefenokee Swamp near Waycross, Georgia . State Road 2 passes through the Florida portion between the Georgia cities of Council and Moniac . The graded Swamp Perimeter Road encircles Okefenokee National Wildlife Refuge. Gated and closed to public use, it provides access for fire management of the interface between the federal refuge and the surrounding industrial tree farms. Many visitors enter

3036-540: The peat archives. In Quaternary Palaeoecology , first published in 1980, Birks and Birks described how paleoecological studies "of peat can be used to reveal what plant communities were present (locally and regionally), what period each community occupied, how environmental conditions changed, and how the environment affected the ecosystem in that time and place." Scientists continue to compare modern mercury (Hg) accumulation rates in bogs with historical natural archives records in peat bogs and lake sediments to estimate

3102-433: The peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand. Peatland features can include ponds, ridges and raised bogs . The characteristics of some bog plants actively promote bog formation. For example, sphagnum mosses actively secrete tannins , which preserve organic material. Sphagnum also have special water-retaining cells, known as hyaline cells, which can release water ensuring

3168-683: The potential human impacts on the biogeochemical cycle of mercury, for example. Over the years, different dating models and technologies for measuring date sediments and peat profiles accumulated over the last 100–150 years, have been used, including the widely used vertical distribution of 210Pb, the inductively coupled plasma mass spectrometry (ICP-SMS), and more recently the initial penetration (IP). Naturally mummified human bodies, often called " bog bodies " have been found in various places in Scotland, England, Ireland, and especially northern Germany and Denmark. They are almost perfectly preserved by

3234-441: The presence of a heat source (e.g., a wildfire penetrating the subsurface), it smoulders. These smouldering fires can burn undetected for very long periods of time (months, years, and even centuries) propagating in a creeping fashion through the underground peat layer. Despite the damage that the burning of raw peat can cause, bogs are naturally subject to wildfires and depend on the wildfires to keep woody competition from lowering

3300-545: The reconstruction of past environments and the study of land-use changes. Peat is used by gardeners and for horticulture in certain parts of the world, but this is being banned in some places. By volume, there are about 4 trillion cubic metres of peat in the world. Over time, the formation of peat is often the first step in the geological formation of fossil fuels such as coal , particularly low-grade coal such as lignite . The peatland ecosystem covers 3.7 million square kilometres (1.4 million square miles) and

3366-614: The rewetting of peatlands and revegetation of native species. This acts to mitigate carbon release in the short term before the new growth of vegetation provides a new source of organic litter to fuel the peat formation in the long term. UNEP is supporting peatland restoration in Indonesia. Latvia has been the biggest exporter of peat in the world by volume, providing more than 19.9% of the world's volume, followed only by Canada with 13% in 2022. In 2020, Latvia exported 1.97 million tons of peat, followed by Germany with 1.5 and Canada with 1.42 million tons. Nevertheless, although first in

Peatland can also be an essential source of drinking water , providing nearly 4% of all potable water stored in reservoirs . In the UK, 43% of the population receives drinking water sourced from peatlands, with the number climbing to 68% in Ireland. Catchments containing peatlands are

3498-479: The safe suppression of this fire. At the peak of fire activity on June 27, 2011, the Honey Prairie Complex had grown to 283,673 acres (114,798 ha) and had 202 engines, 112 dozers, 20 water tenders, 12 helicopters, and 6 crews with a total of 1,458 personnel assigned. Over the duration of the fire, there were no fatalities or serious injuries. Firefighters managed to contain most of the fire within

3564-628: The same bog about 60 metres (200 ft) from the Tollund Man. She is believed to have lived during the late 3rd century BC and was a ritual sacrifice. In the Bronze and Iron Ages, people used peat bogs for rituals to nature gods and spirits. The distinctive ecological conditions of peat wetlands provide a habitat for distinctive fauna and flora. For example, whooping cranes nest in North American peatlands, whilst Siberian cranes nest in

3630-511: The state whilst 23% belong to the municipalities Bogs in Latvia are considered important habitats due to their ecological values, and up to 128,000 hectares, or 40% of the areas in the territory, are protected by environmental laws. The most famous national parks and reserves are the Ķemeri National Park , Cenas tīrelis and Teiči Nature Reserve . The climate, geography and environment of Finland favours bog and peat bog formation. Thus, peat

The St. Marys River , which drains only 5 to 10 percent of the swamp's southeastern corner, flows south along the western side of Trail Ridge, through the ridge at St. Marys River Shoals, and north again along the eastern side of Trail Ridge before turning east to the Atlantic. The earliest known inhabitants of the Okefenokee Swamp were

3762-450: The topic. In 2010, IPS presented a " Strategy for Responsible Peatland Management ", which can be applied worldwide for decision-making. Peat extraction is forbidden in Chile since April 2024. Often, restoration is done by blocking drainage channels in the peatland, and allowing natural vegetation to recover. Rehabilitation projects undertaken in North America and Europe usually focus on

3828-410: The tropical to boreal and Arctic zones from sea level to high alpine conditions. A more recent estimate from an improved global peatland map, PEATMAP, based on a meta-analysis of geospatial information at global, regional and national levels puts global coverage slightly higher than earlier peatland inventories at 4.23 million square kilometres (1.63 million square miles) approximately 2.84% of

3894-812: The water table and shading out many bog plants. Several families of plants including the carnivorous Sarracenia (trumpet pitcher), Dionaea (Venus flytrap), Utricularia (bladderworts) and non-carnivorous plants such as the sandhills lily , toothache grass and many species of orchid are now threatened and in some cases endangered from the combined forces of human drainage, negligence and absence of fire. The recent burning of peat bogs in Indonesia, with their large and deep growths containing more than 50 billion tonnes (55 billion short tons; 49 billion long tons) of carbon, has contributed to increases in world carbon dioxide levels. Peat deposits in Southeast Asia could be destroyed by 2040. It

Many traditional spa treatments include peat as part of peloids . Such health treatments have an enduring tradition in European countries, including Poland, the Czech Republic, Germany and Austria. Some of these old spas date back to the 18th century and are still active today. The most common types of peat application in balneotherapy are peat muds , poultices and suspension baths . Authors Rydin and Jeglum in Biology of Habitats described

4026-436: The world by volume, in monetary terms, Latvian comes second in the world behind Canada . As an example, Latvia's income from exports was US$ 237 million. Latvia's peat deposits have been estimated to equal 1.7 billion tons. Latvia, as Finland due its climate has several peat bogs, which account for 9.9% of the country's territory. More than two thirds of the licensed areas for peat extraction are state-owned; 55% belong to

4092-479: The world land area. In Europe, peatlands extend to about 515,000 km (199,000 sq mi). About 60% of the world's wetlands are made of peat. Peat deposits are found in many places around the world, including northern Europe and North America. The North American peat deposits are principally found in Canada and the Northern United States. Some of the world's largest peatlands include

4158-466: The worldwide 500,000 km of degraded peatland may exceed 2.0 Gtons (including emissions from peat fires), which is almost 6% of all global carbon emissions. Peat can be a major fire hazard and is not extinguished by light rain. Peat fires may burn for great lengths of time, or smoulder underground and reignite after winter if an oxygen source is present. Peat has a high carbon content and can burn under low moisture conditions. Once ignited by

4224-399: Was designated a National Natural Landmark in 1974. The name Okefenokee is attested with more than a dozen variant spellings of the word in historical literature. Though often translated as "land of trembling earth", the name is likely derived from Hitchiti oki fanôːki "bubbling water". The Okefenokee was formed over the past 6,500 years by the accumulation of peat in a shallow basin on

Over 60,000 people sent comments opposing the operation. Later, in 2020, a new rule by the first Trump administration reduced what was protected under the Clean Water Act , removing about 400 acres (160 ha) in the proposed mining site from federal protections. The updated plan would include mining 577.4 acres (233.7 ha) for titanium and zirconium, 2.9 miles (4.7 km) southeast of
