The city of Campeche is south of the reserve. The reserve includes coastal beaches and dunes, which enclose lagoons and wetlands. There are low uplands in the eastern portion of the reserve. The reserve protects extensive mangrove wetlands, part of

244-481: A famous world map was produced. In 1506 Hernán Cortés took part in the conquest of Hispaniola and Cuba, receiving a large estate of land and indigenous slaves for his effort. In 1510 he accompanied Diego Velázquez de Cuéllar , an aide of the governor of Hispaniola, in his expedition to conquer Cuba. In 1518 Velázquez put him in command of an expedition to explore and secure the interior of Mexico for colonization. In 1517 Francisco Hernández de Córdoba discovered

366-578: A hypoxic dead zone that runs east–west along the Texas–Louisiana coastline. In July 2008, researchers reported that between 1985 and 2008, the area roughly doubled in size. It was 8,776 square miles (22,730 km ) in 2017, the largest ever recorded. Poor agricultural practices in the northern portion of the Gulf of Mexico have led to a tremendous increase of nitrogen and phosphorus in neighboring marine ecosystems, which has resulted in algae blooms and

There were no reports of damage or injuries. Items were knocked from shelves and seiches were observed in swimming pools in parts of Florida. The earthquake was described by the USGS as an intraplate earthquake , the largest and most widely felt recorded in

610-486: A poll tax and literacy test . The 1901 constitution required racial segregation of public schools. By 1903 only 2,980 African Americans were registered in Alabama, although at least 74,000 were literate . This compared to more than 181,000 African Americans eligible to vote in 1900. The numbers dropped even more in later decades. The state legislature passed additional racial segregation laws related to public facilities into

1464-561: A lawsuit and court order. Beginning in the 1940s, when the courts started taking the first steps to recognize the voting rights of black voters, the Alabama legislature took several counter-steps designed to disfranchise black voters. The legislature passed, and the voters ratified [as these were mostly white voters], a state constitutional amendment that gave local registrars greater latitude to disqualify voter registration applicants. Black citizens in Mobile successfully challenged this amendment as

Coast Guard Rear Admiral Sally Brice O'Hare stated that the U.S. government will be "employing booms, skimmers, chemical dispersants and controlled burns" to combat the oil spill. By May 1 the oil spill cleanup efforts were underway but hampered by rough seas and the "tea like" consistency of

1830-584: A significant minority in the state, they had been unable to elect any representatives in most of the at-large jurisdictions. As part of settlement of this case, five Alabama cities and counties, including Chilton County , adopted a system of cumulative voting for election of representatives in multi-seat jurisdictions. This has resulted in more proportional representation for voters. In another form of proportional representation, 23 jurisdictions use limited voting , as in Conecuh County . In 1982, limited voting

1952-582: A slight majority of those disenfranchised by these laws: 600,000 whites vs. 520,000 African Americans. Nearly all blacks had lost the ability to vote. Despite numerous legal challenges which succeeded in overturning certain provisions, the state legislature would create new ones to maintain disenfranchisement. The exclusion of blacks from the political system persisted until after passage of federal civil rights legislation in 1965 to enforce their constitutional rights as citizens. The rural-dominated Alabama legislature consistently underfunded schools and services for

2074-585: A violation of the Fifteenth Amendment . The legislature also changed the boundaries of Tuskegee to a 28-sided figure designed to fence out blacks from the city limits. The Supreme Court unanimously held that this racial " gerrymandering " violated the Constitution. In 1961,   ... the Alabama legislature also intentionally diluted the effect of the black vote by instituting numbered place requirements for local elections. Industrial development related to

2440-623: Is an excellent example of a passive margin . The continental shelf is quite wide at most points along the coast, most notably at the Florida and Yucatán Peninsulas. The shelf is exploited for its oil by means of offshore drilling rigs, most of which are situated in the western gulf and in the Bay of Campeche. Another important commercial activity is fishing; major catches include red snapper , amberjack , tilefish , swordfish , and various grouper , as well as shrimp and crabs. Oysters are also harvested on

2562-572: Is common in the U.S. An estimated 26 states have names of Native American origin. Sources disagree on the word's meaning. Some scholars suggest the word comes from the Choctaw alba (meaning 'plants' or 'weeds') and amo (meaning 'to cut', 'to trim', or 'to gather'). The meaning may have been 'clearers of the thicket' or 'herb gatherers', referring to clearing land for cultivation or collecting medicinal plants. The state has numerous place names of Native American origin . An 1842 article in

In the Alabama language , the word for a person of Alabama lineage is Albaamo (or variously Albaama or Albàamo in different dialects; the plural form is Albaamaha ). The word's spelling varies significantly among historical sources. The first usage appears in three accounts of

3660-503: The American Revolutionary War . Spain held Mobile as part of Spanish West Florida until 1813. In December 1819, Alabama was recognized as a state. During the antebellum period, Alabama was a major producer of cotton , and widely used African American slave labor . In 1861, the state seceded from the United States to become part of the Confederate States of America , with Montgomery acting as its first capital, and rejoined

3782-621: The Blaine Amendment , prohibiting public money from being used to finance religious-affiliated schools. The same year, legislation was approved that called for racially segregated schools. Railroad passenger cars were segregated in 1891. The new 1901 constitution of Alabama included provisions for voter registration that effectively disenfranchised large portions of the population, including nearly all African Americans and Native Americans, and tens of thousands of poor European Americans, through making voter registration difficult, requiring

Particularly during the Cenozoic, a time of relative stability for the coastal zones, thick clastic wedges built out the continental shelf along the northwestern and northern margins of the basin. To the east, the stable Florida Platform

4636-644: The Montgomery bus boycott (1955–1956), Freedom Rides in 1961, and 1965 Selma to Montgomery marches. These contributed to Congressional passage and enactment of the Civil Rights Act of 1964 and Voting Rights Act of 1965 by the U.S. Congress. Legal segregation ended in the states in 1964, but Jim Crow customs often continued until specifically challenged in court. According to The New York Times , by 2017, many of Alabama's African Americans were living in Alabama's cities such as Birmingham and Montgomery. Also,

The agrarian Mississippian culture covered most of the state from 1000 to 1600 CE, with one of its major centers built at what is now the Moundville Archaeological Site in Moundville, Alabama . This is the second-largest complex of the classic Middle Mississippian era, after Cahokia in present-day Illinois , which

5246-589: The Upper South brought slaves with them as the cotton plantations in Alabama expanded. The economy of the central Black Belt (named for its dark, productive soil) was built around large cotton plantations whose owners' wealth grew mainly from slave labor. The area also drew many poor, disenfranchised people who became subsistence farmers . Alabama had an estimated population of under 10,000 people in 1810, but it increased to more than 300,000 people by 1830. Most Native American tribes were completely removed from

Areas in Alabama administered by the National Park Service include Horseshoe Bend National Military Park near Alexander City ; Little River Canyon National Preserve near Fort Payne ; Russell Cave National Monument in Bridgeport ; Tuskegee Airmen National Historic Site in Tuskegee; and Tuskegee Institute National Historic Site near Tuskegee. Additionally, Alabama has four National Forests : Conecuh , Talladega , Tuskegee , and William B. Bankhead . Alabama also contains

5490-405: The "Magic City". By 1920, Birmingham was the 36th-largest city in the United States. Heavy industry and mining were the basis of its economy. Its residents were under-represented for decades in the state legislature, which refused to redistrict after each decennial census according to population changes, as it was required by the state constitution. This did not change until the late 1960s following

5612-404: The 1950s: jails were segregated in 1911; hospitals in 1915; toilets, hotels, and restaurants in 1928; and bus stop waiting rooms in 1945. While the planter class had persuaded poor whites to vote for this legislative effort to suppress black voting, the new restrictions resulted in their disenfranchisement as well, due mostly to the imposition of a cumulative poll tax. By 1941, whites constituted

Alabama was admitted as the 22nd state on December 14, 1819, with Congress selecting Huntsville as the site for the first Constitutional Convention . From July   5 to August 2, 1819, delegates met to prepare the new state constitution. Huntsville served as temporary capital from 1819 to 1820, when

5856-519: The Alabama legislature." In the United States Supreme Court cases of Baker v. Carr (1962) and Reynolds v. Sims (1964), the court ruled that the principle of " one man, one vote " needed to be the basis of both houses of state legislatures, and that their districts had to be based on population rather than geographic counties. African Americans continued to press in the 1950s and 1960s to end disenfranchisement and segregation in

5978-468: The Atlantic Ocean was established that the deposition of Louann Salt ceased. Seafloor spreading stopped at the end of the Jurassic, about 145–150 million years ago. During the late Jurassic through early Cretaceous, the basin experienced a period of cooling and subsidence of the crust underlying it. The subsidence was the result of a combination of crustal stretching, cooling, and loading. Initially,

In 1972, for the first time since 1901, the legislature completed the congressional redistricting based on the decennial census. This benefited the urban areas that had developed, as well as all in the population who had been underrepresented for more than sixty years. Other changes were made to implement representative state house and senate districts. Alabama has made some changes since

Vespucci is purported to have followed the coastal land mass of Central America before returning to the Atlantic Ocean via the Straits of Florida between Florida and Cuba. However, this first voyage of 1497 is widely disputed, and many historians doubt that it took place as described. In his letters, Vespucci described this trip, and once Juan de la Cosa returned to Spain,

Black residents effectively taxed themselves twice, by raising additional monies to supply matching funds for such schools, which were built in many rural areas. They often donated land and labor as well. Beginning in 1913, the first 80 Rosenwald Schools were built in Alabama for African American children. A total of 387 schools, seven teachers' houses, and several vocational buildings were completed by 1937 in

8784-702: The delimitation of the continental shelf in the western Gulf of Mexico beyond 200 nautical miles (370 km; 230 mi), of June 9, 2000. On December 13, 2007, Mexico submitted information to the Commission on the Limits of the Continental Shelf (CLCS) regarding the extension of Mexico's continental shelf beyond 200 nautical miles. Mexico sought an extension of its continental shelf in the Western Polygon based on international law, UNCLOS, and bilateral treaties with

8906-438: The demands of World War II brought a level of prosperity to the state not seen since before the civil war. Rural workers poured into the largest cities in the state for better jobs and a higher standard of living. One example of this massive influx of workers occurred in Mobile. Between 1940 and 1943, more than 89,000 people moved into the city to work for war-related industries. Cotton and other cash crops faded in importance as

9028-401: The depths and making it less likely that further hurricanes will follow in its wake (warm water being one of the preconditions necessary for their formation). However, the gulf is shallower; when a hurricane passes over the water temperature may drop but it soon rebounds and becomes capable of supporting another tropical storm. From 1970 to 2020, surface temperatures warmed at approximately twice

9150-513: The disenfranchised African Americans, but it did not relieve them of paying taxes. Partially as a response to chronic underfunding of education for African Americans in the South, the Rosenwald Fund began funding the construction of what came to be known as Rosenwald Schools . In Alabama, these schools were designed, and the construction partially financed with Rosenwald funds, which paid one-third of

9272-459: The early decades of the 20th century as part of the Great Migration out of the South. Reflecting this emigration, the population growth rate in Alabama (see "historical populations" table below) dropped by nearly half from 1910 to 1920. At the same time, many rural people migrated to the city of Birmingham to work in new industrial jobs. Birmingham experienced such rapid growth it was called

There are frequent " red tide " algae blooms that kill fish and marine mammals and cause respiratory problems in humans and some domestic animals when the blooms reach close to shore. This has especially been plaguing the southwest and southern Florida coast, from the Florida Keys to north of Pasco County, Florida . The gulf contains

10004-553: The gulf's shoreline is fringed by numerous bays and smaller inlets. Stream that empty into the gulf include the Mississippi River and the Rio Grande in the northern gulf, and the Grijalva and Usumacinta rivers in the southern gulf. The land that forms the gulf's coast, including many long, narrow barrier islands, is almost uniformly low-lying and is characterized by marshes and swamps as well as stretches of sandy beach. The Gulf of Mexico

10126-506: The gulf. These have generally not been checked for potential environmental problems. In 1973 the United States Environmental Protection Agency prohibited the dumping of undiluted chemical waste by manufacturing interests into the gulf, and the military confessed to similar behavior in waters off Horn Island . Microplastics within semi-enclosed seas like the gulf have been reported in high concentrations, and

10248-480: The impact of the Deepwater Horizon oil spill . In Congressional testimony, Dr. Jonathan Coddington, associate director of Research and Collections at the Smithsonian's National Museum of Natural History , provides a detailed overview of the Gulf collections and their sources which Museum staff have made available on an online map. The samples were collected for years by the former Minerals Management Service (renamed

10370-1238: The lagoons, and tropical dry forests in the uplands. The reserve is home to large and diverse populations of migratory and resident birds, with over 300 species identified. 56% of species are year-round residents, 43% are seasonal, and 1% are occasional visitors. Bird species present include the American flamingo ( Phoenicopterus ruber ), jabiru ( Jabiru mycteria ), wood stork ( Mycteria americana ), Muscovy duck ( Cairina moschata ), snail kite ( Rostrhamus sociabilis ), orange oriole ( Icterus auratus ), hooded oriole ( Icterus cucullatus ), least tern ( Sternula antillarum ), crane hawk ( Geranospiza caerulescens ), common black hawk ( Buteogallus anthracinus ), black hawk-eagle ( Spizaetus tyrannus ), Yucatan amazon ( Amazona xantholora ), bat falcon ( Falco rufigularis ), ferruginous pygmy owl ( Glaucidium brasilianum ), least bittern ( Ixobrychus exilis ), reddish egret ( Egretta rufescens ), blue-winged teal ( Spatula discors ), northern pintail ( Anas acuta ), American wigeon ( Mareca americana ), lesser scaup ( Aythya affinis ), king vulture ( Sarcoramphus papa ), and hen harrier ( Circus cyaneus ).

10614-430: The late 20th century and has used new types of voting to increase representation. In the 1980s, an omnibus redistricting case, Dillard v. Crenshaw County , challenged the at-large voting for representative seats of 180 Alabama jurisdictions, including counties and school boards. At-large voting had diluted the votes of any minority in a county, as the majority tended to take all seats. Despite African Americans making up

10736-488: The mainland being considered to be within the Gulf. The consensus among geologists is that before the late Triassic , the Gulf of Mexico did not exist. Before the Late Triassic, the area consisted of dry land, which included continental crust that now underlies Yucatán , within the middle of the supercontinent Pangaea . This land lay south of a continuous mountain range that extended from north-central Mexico, through

On January 25, 1699, d'Iberville reached Santa Rosa Island near Pensacola founded by the Spanish; he sailed from there to Mobile Bay and explored Massacre Island, later renamed Dauphin Island . He cast anchor between Cat Island and Ship Island ; and on February 13 he went to

11102-458: The oil. Cleanup operations were resumed after conditions became favorable. On May 27 the USGS had revised the estimate of the leak from 5,000 barrels per day (790 m /d) to 12,000–19,000 barrels per day (3,000 m /d) an increase from earlier estimates. On July 15 BP announced that the leak had stopped for the first time in 88 days. In July BP reached an $ 18.7bn settlement with the U.S. government,

11224-603: The past three decades in the region. According to the September 11, 2006 issue of The Tampa Tribune , earthquake tremors were last felt in Florida in 1952, recorded in Quincy , 20 miles (32 km) northwest of Tallahassee . Cuba and Mexico: Exchange of notes constituting an agreement on the delimitation of the exclusive economic zone of Mexico in the sector adjacent to Cuban maritime areas (with map), of July 26, 1976. Cuba and United States: Maritime boundary agreement between

11346-469: The rate observed for the global ocean surface. The gulf is considered aseismic ; however, mild tremors have been recorded throughout history (usually 5.0 or less on the Richter magnitude scale ). Earthquakes may be caused by interactions between sediment loading on the sea floor and adjustment by the crust. On September 10, 2006, the U.S. Geological Survey National Earthquake Information Center reported that

11468-468: The salvage operation, when Alvarado arrived by sea on July 22, 1554. The team labored until September 12 to salvage the Padre Island treasure. This loss, in combination with other ship disasters around the Gulf of Mexico, gave rise to a plan for establishing a settlement on the northern Gulf Coast to protect shipping and more quickly rescue castaways. As a result, the expedition of Tristán de Luna y Arellano

It borders Tennessee to the north, Georgia to the east, Florida and the Gulf of Mexico to

11712-617: The seat of government moved to Cahaba in Dallas County . Cahaba , now a ghost town , was the first permanent state capital from 1820 to 1825. The Alabama Fever land rush was underway when the state was admitted to the Union, with settlers and land speculators pouring into the state to take advantage of fertile land suitable for cotton cultivation. Part of the frontier in the 1820s and 1830s, its constitution provided for universal suffrage for white men. Southeastern planters and traders from

11834-520: The second in 1519 under the command of Hernán Cortés , which led to the Spanish exploration, military invasion, and ultimately settlement and colonization known as the Conquest of Mexico . Hernández did not live to see the continuation of his work: he died in 1517, the year of his expedition, as the result of the injuries and the extreme thirst suffered during the voyage, and disappointed in the knowledge that Diego Velázquez had given precedence to Grijalva as

11956-610: The sleeves, collar and coattails. This led to them being greeted with "Yellowhammer", and the name later was applied to all Alabama troops in the Confederate Army. Alabama's slaves were freed by the 13th Amendment in 1865. Alabama was under military rule from the end of the war in May 1865 until its official restoration to the Union in 1868. From 1867 to 1874, with most white citizens barred temporarily from voting and freedmen enfranchised, many African Americans emerged as political leaders in

12078-469: The south, and Mississippi to the west. Alabama is the 30th largest by area , and the 24th-most populous of the 50 U.S. states . Alabama is nicknamed the Yellowhammer State , after the state bird . Alabama is also known as the "Heart of Dixie " and the "Cotton State". The state has diverse geography, with the north dominated by the mountainous Tennessee Valley and the south by Mobile Bay ,

12200-598: The state a major focal point of the civil rights movement in the 1950s and 1960s. During and after World War II , Alabama grew as the state's economy diversified with new industries. In 1960, the establishment of NASA 's Marshall Space Flight Center in Huntsville helped boost Alabama's economic growth by developing a local aerospace industry. Alabama's economy in the 21st century is based on automotive, finance, tourism, manufacturing, aerospace, mineral extraction, healthcare, education, retail, and technology. The name of

12322-414: The state developed a manufacturing and service base. Despite massive population changes in the state from 1901 to 1961, the rural-dominated legislature refused to reapportion House and Senate seats based on population, as required by the state constitution to follow the results of decennial censuses. They held on to old representation to maintain political and economic power in agricultural areas. One result

12444-454: The state in the twenty-first century. In 2004, Hurricane Ivan , a category 3 storm upon landfall, struck the state and caused over $ 18 billion of damage. It was among the most destructive storms to strike the state in its modern history. A super outbreak of 62 tornadoes hit the state in April 2011 and killed 238 people, devastating many communities. Alabama is the thirtieth-largest state in

12566-457: The state through the civil rights movement, including legal challenges. In 1954, the U.S. Supreme Court ruled in Brown v. Board of Education that public schools had to be desegregated , but Alabama was slow to comply. During the 1960s, under Governor George Wallace , Alabama resisted compliance with federal demands for desegregation. The civil rights movement had notable events in Alabama, including

12688-610: The state within a few years of the passage of the Indian Removal Act by Congress in 1830. From 1826 to 1846, Tuscaloosa served as Alabama's capital. On January 30, 1846, the Alabama legislature announced it had voted to move the capital city from Tuscaloosa to Montgomery. The first legislative session in the new capital met in December 1847. A new capitol building was erected under the direction of Stephen Decatur Button of Philadelphia . The first structure burned down in 1849, but

12810-513: The state, particularly Huntsville, benefited from the opening of the George C. Marshall Space Flight Center in 1960, a major facility in the development of the Saturn rocket program and the space shuttle. Technology and manufacturing industries, such as automobile assembly, replaced some the state's older industries in the late twentieth century, but the state's economy and growth lagged behind other states in

12932-749: The state. Alabama was represented in Congress during this period by three African-American congressmen: Jeremiah Haralson , Benjamin S. Turner , and James T. Rapier . Following the war, the state remained chiefly agricultural, with an economy tied to cotton. During the Reconstruction era, state legislators ratified a new state constitution in 1868 which created the state's first public school system and expanded women's rights. Legislators funded numerous public road and railroad projects, although these were plagued with allegations of fraud and misappropriation . Organized insurgent , resistance groups tried to suppress

13054-476: The state. Several of the surviving school buildings in the state are now listed on the National Register of Historic Places . Continued racial discrimination and lynchings , agricultural depression, and the failure of the cotton crops due to boll weevil infestation led tens of thousands of African Americans from rural Alabama and other states to seek opportunities in northern and midwestern cities during

13176-409: The states of Alabama, Florida, Louisiana, Mississippi and Texas, as well as 400 local authorities. As of 2015 BP's cost for the clean-up, environmental and economic damages and penalties has reached $ 54bn. On May 12, 2016, a release of oil from subsea infrastructure on Shell's Brutus oil rig released 2,100 barrels of oil. This leak created a visible 2 by 13 miles (3.2 by 20.9 km) oil slick in

13298-546: The strongest ocean currents known, originates in the gulf as a continuation of the Caribbean Current –Yucatán Current– Loop Current system. Other circulation features include a permanent cyclonic gyre in the Bay of Campeche, as well as anticyclonic gyres which are shed by the Loop Current and travel westward where they eventually dissipate. The Bay of Campeche constitutes a major arm of the Gulf of Mexico. Additionally,

13420-657: The surrender of the Spanish garrison at Mobile to U.S. forces on April 13, 1813. Thomas Bassett, a loyalist to the British monarchy during the Revolutionary era, was one of the earliest white settlers in the state outside Mobile.

Spain kept a claim on its former Spanish West Florida territory in what would become the coastal counties until the Adams–Onís Treaty officially ceded it to the U.S. in 1819. Before Mississippi's admission to statehood on December 10, 1817, the more sparsely settled eastern half of the territory was separated and named the Alabama Territory . The United States Congress created

13664-414: The wide continental shelves of Yucatán and Florida receive cooler, nutrient-enriched waters from the deep by a process known as upwelling , which stimulates plankton growth in the euphotic zone . This attracts fish, shrimp, and squid. River drainage and atmospheric fallout from industrial coastal cities also provide nutrients to the coastal zone. The Gulf Stream , a warm Atlantic Ocean current and one of

13786-462: Was claimed by BP that approximately 1,000 barrels (160 m ) of oil per day were issuing from the wellhead , about 1-mile (1.6 km) below the surface on the ocean floor. On April 29, the U.S. government revealed that approximately 5,000 barrels (790 m ) per day, five times the original estimate, were pouring into the gulf from the wellhead. The resulting oil slick quickly expanded to cover hundreds of square miles of ocean surface, posing

13908-528: Was first tested in Conecuh County. Together use of these systems has increased the number of African Americans and women being elected to local offices, resulting in governments that are more representative of their citizens. Beginning in the 1960s, the state's economy shifted away from its traditional lumber, steel, and textile industries because of increased foreign competition. Steel jobs, for instance, declined from 46,314 in 1950 to 14,185 in 2011. However,

14030-538: Was involved during the latest Cretaceous and early Paleogene periods in a compressive deformation episode, the Laramide Orogeny , which created the Sierra Madre Oriental of eastern Mexico. In 2014, Erik Cordes of Temple University and others discovered a brine pool 3,300 feet (1,000 m) below the gulf's surface, with a circumference of 100 feet (30 m) and 12 feet (3.7 m) feet deep, which

14152-502: Was moved to the current site of Mobile in 1711. This area was claimed by the French from 1702 to 1763 as part of La Louisiane . After the French lost to the British in the Seven Years' War , it became part of British West Florida from 1763 to 1783. After the U.S. victory in the American Revolutionary War , the territory was divided between the United States and Spain. The latter retained control of this western territory from 1783 until

14274-402: Was not covered by the sea until the latest Jurassic or the beginning of Cretaceous time. The Yucatán Platform was emergent until the mid-Cretaceous. After both platforms were submerged, the formation of carbonates and evaporites has characterized the geologic history of these two stable areas. Most of the basin was rimmed during the early Cretaceous by carbonate platforms, and its western flank

14396-543: Was rebuilt on the same site in 1851. This second capitol building in Montgomery remains to the present day. It was designed by Barachias Holt of Exeter, Maine . By 1860, the population had increased to 964,201 people, of which nearly half, 435,080, were enslaved African Americans, and 2,690 were free people of color . On January 11, 1861, Alabama declared its secession from the Union . After remaining an independent republic for

On December 11, 1526, Charles V granted Pánfilo de Narváez a license to claim what is now the Gulf Coast of the United States, known as the Narváez expedition . The contract gave him one year to gather an army, leave Spain, be large enough to found at least two towns of 100 people each, and garrison two more fortresses anywhere along

14640-475: Was stretched and thinned. This thinning created a broad zone of transitional crust, which displays modest and uneven thinning with block faulting and a broad zone of uniformly thinned transitional crust, which is half the typical 40- kilometer (25  mi ) thickness of continental crust. It was at this time that rifting first created a connection to the Pacific Ocean across central Mexico and later eastward to

14762-413: Was that Jefferson County , containing Birmingham's industrial and economic powerhouse, contributed more than one-third of all tax revenue to the state, but did not receive a proportional amount in services. Urban interests were consistently underrepresented in the legislature. A 1960 study noted that because of rural domination, "a minority of about 25% of the total state population is in majority control of

14884-527: Was the center of the culture. Analysis of artifacts from archaeological excavations at Moundville were the basis of scholars' formulating the characteristics of the Southeastern Ceremonial Complex (SECC). Contrary to popular belief, the SECC appears to have no direct links to Mesoamerican culture but developed independently. The Ceremonial Complex represents a major component of the religion of
