44-768: Black Bayou Lake is studded with cypress and tupelo trees, and surrounded by swamps that graduate into bottomland hardwoods and then into upland mixed pine/hardwoods. Cherrybark oak , cedar elm , ash , hickories and willow oak dominate the lower areas while shortleaf pine , loblolly pine , mockernut hickory and post oak dominate the upland sites. Common wildlife seen include alligators , wood ducks , bird-voiced treefrogs , banded water snakes , red-eared sliders , green herons , coyotes , skunks , and white-tailed deer . The refuge supports an excellent fisheries resource and provides valuable habitat for migratory waterfowl, neotropical migratory songbirds, and many resident wildlife species. Biology professors and students from

88-664: A pyramidal form, particularly in their youth. Many are characterised by their needle-like, evergreen foliage and acorn -like seed cones. Some species develop flattened, spreading heads at maturity, while certain variants may manifest as shrubs, standing at less than 6 metres (20 ft). The bark of cypress trees varies, with some species having smooth surfaces, while most exhibit bark that separates into thin plates or strips, often shedding over time. Leaves of young cypress trees are spreading and awl-shaped, and are typically small, scale-like formations that tightly adhere to older branches. They are usually aromatic , with glandular pits on

132-751: A central role in the mound-building peoples' religious life. Documented uses include semi-public chief 's house platforms, public temple platforms, mortuary platforms, charnel house platforms, earth lodge /town house platforms, residence platforms, square ground and rotunda platforms, and dance platforms. Cultures that built substructure mounds include the Troyville culture , Coles Creek culture , Plaquemine culture and Mississippian cultures . Many square flat-topped mound tombs in China . The first emperor Qin Shi Huang ( c.  221 BC , who unified

Several circular stepped pyramids called Guachimontones survive in Teuchitlán, Jalisco . Pyramids in Mexico were often used for human sacrifice . Harner stated that for the dedication of the Great Pyramid of Tenochtitlan in 1487, "one source states 20,000, another 72,344, and several give 80,400" as

220-481: A large nest box program for prothonotary warblers and wood ducks. Wood ducks are banded on the refuge each year. An area of 800 acres (3.2 km) of former agricultural fields has been reforested with eleven bottomland hardwood tree species. Existing forested wetlands are managed for forest health and wildlife habitat. The small upland area on the east side of the refuge is home to a remnant red-cockaded woodpecker (RCW) cluster. Some hardwoods have been removed to create

264-469: A preferred habitat for this endangered species. Establishing the arboretum and prairie demonstration areas required repeated plantings and waterings. Annual mowing or burning maintains the prairie area. Some of the young arboretum trees must be protected from deer and rabbits with wire cages. Control of exotic species (those not occurring naturally in this area) is a major activity on this refuge. Herbicide spraying helps to prevent water hyacinths from covering

308-487: A pyramid can be of any polygon shape, such as triangular or quadrilateral , and its lines either filled or stepped. A pyramid has the majority of its mass closer to the ground with less mass towards the pyramidion at the apex . This is due to the gradual decrease in the cross-sectional area along the vertical axis with increasing elevation. This offers a weight distribution that allowed early civilizations to create monumental structures. Civilizations in many parts of

Neither survives and no evidence indicates that they resembled Egyptian pyramids. At least two surviving pyramid-like structures are available to study, one at Hellenikon and the other at Ligourio/Ligurio,

440-420: A tomb alleged to be the tomb of Amphion and Zethus near Thebes , a structure at Stylidha ( Thessaly ) which is a long wall, etc. She pushed the possibility that the stones that were dated might have been recycled from earlier constructions. She claimed that earlier research from the 1930s, confirmed in the 1980s by Fracchia, was ignored. Liritzis responded that Lefkowitz failed to understand and misinterpreted

484-460: A village near the ancient theatre Epidaurus . These buildings have inwardly sloping walls, but bear no other resemblance to Egyptian pyramids. They had large central rooms (unlike Egyptian pyramids) and the Hellenikon structure is rectangular rather than square, 12.5 by 14 metres (41 by 46 ft) which means that the sides could not have met at a point. The stone used to build these structures

At least nine Buddhist step pyramids survive, 4 from former Gyeongsang Province of Korea, 3 from Japan, 1 from Indonesia (Borobudur) and 1 from Tajikistan . Several pyramids were erected throughout the Pacific islands, such as Puʻukoholā Heiau in Hawaii ,

660-687: Is the largest pre- colonial architectural monument in Gao. It is a notable example of the Sudano-Sahelian architectural style that later spread throughout the region. One of the unique structures of Igbo culture was the Nsude pyramids, in the Nigerian town of Nsude, northern Igboland . Ten pyramidal structures were built of clay/mud. The first base section was 60 ft (18 m) in circumference and 3 ft (0.9 m) in height. The next stack

704-1176: The Airavatesvara Temple at Darasuram . However, the largest temple (area) is the Ranganathaswamy Temple in Srirangam, Tamil Nadu . The Thanjavur temple was built by Raja Raja Chola in the 11th century. The Brihadisvara Temple was declared a World Heritage Site by UNESCO in 1987; the Temple of Gangaikondacholapuram and the Airavatesvara Temple at Darasuram were added in 2004. Austronesian megalithic culture in Indonesia featured earth and stone step pyramid structures called punden berundak. These were discovered in Pangguyangan near Cisolok and in Cipari near Kuningan. The stone pyramids were based on beliefs that mountains and high places were

748-469: The Black Athena controversy. Lefkowitz criticised this research, suggesting that some of the research was done not to determine the reliability of the dating method, as was suggested, but to back up a claim and to make points about pyramids and Greek civilization. She claimed that not only were the results imprecise, but that other structures mentioned in the research are not in fact pyramids, e.g.

792-711: The Nubians who ruled Egypt in the Late Period. The Great Pyramid of Giza is the largest in Egypt and one of the largest in the world. At 146.6 metres (481 ft) it was the tallest structure in the world until the Lincoln Cathedral was finished in 1311 AD. Its base covers an area of around 53,000 square metres (570,000 sq ft). The Great Pyramid is the only extant one of the Seven Wonders of

836-932: The Pulemelei Mound in Samoa , and Nan Madol in Pohnpei . With the Egyptian Revival movement in the nineteenth and early twentieth century, pyramids became more common in funerary architecture. The tomb of Quintino Sella , outside the monumental cemetery of Oropa , is pyramid-shaped. This style was popular with tycoons in the US. The Schoenhofen Pyramid Mausoleum (1889) in Chicago and Hunt's Tomb (1930) in Phoenix, Arizona are notable examples. Some people build pyramid tombs for themselves. Nicolas Cage bought

The alligator snapping turtle , a species that has declined drastically across most of the south, nests along the shores of the lake. Nest surveys are conducted annually. Reducing the raccoon population helps to prevent destruction of all the alligator snapping turtle nests and many of other turtles species. The refuge has

1012-480: The feudal era, e.g. as the tower of Oviedo 's Gothic Cathedral of San Salvador . Andean cultures used pyramids in various architectural structures such as the ones in Caral , Túcume and Chavín de Huantar , constructed around the same time as early Egyptian pyramids. Several Mesoamerican cultures built pyramid-shaped structures. Mesoamerican pyramids were usually stepped, with temples on top, more similar to

1056-422: The sap that typically drips down the tree's trunk represents Cyparissus' tears. Consequently, the cypress emerged as a symbol of mourning, sadness, and loss in classical mythology, thereby serving an aetiological purpose in explaining its cultural significance. Due to its connection to grief, the cypress became one of the symbols of Hades and has been planted in cemeteries since the classical era . During

1100-481: The Ancient World . Ancient Egyptian pyramids were, in most cases, placed west of the river Nile because the divine pharaoh's soul was meant to join with the sun during its descent before continuing with the sun in its eternal round. As of 2008, some 135 pyramids had been discovered in Egypt, most located near Cairo. While African pyramids are commonly associated with Egypt, Sudan has 220 extant pyramids,

Constructed from the 3rd century BC to the 9th century AD, this pyramid is the world's largest monument, and is still not fully excavated. The third largest pyramid in the world, the Pyramid of the Sun , at Teotihuacan , is also located in Mexico . An unusual pyramid with

1188-705: The abode for the spirit of the ancestors . The step pyramid is the basic design of the 8th century Borobudur Buddhist monument in Central Java . However later Java temples were influenced by Indian Hindu architecture , as exemplified by the spires of Prambanan temple. In the 15th century, during late Majapahit period, Java saw the revival of indigenous Austronesian elements as displayed by Sukuh temple that somewhat resemble Mesoamerican pyramids, and also stepped pyramids of Mount Penanggungan. In east Asia, Buddhist stupas were usually represented as tall pagodas . However, some pyramidal stupas survive. One theory

1232-416: The core of the ziggurat with facings of fired bricks on the outside. The facings were often glazed in different colors and may have had astrological significance. Kings sometimes had their names engraved on them. The number of tiers ranged from two to seven. It is assumed that they had shrines at the top, but no archaeological evidence supports this and the only textual evidence is from Herodotus . Access to

1276-487: The earliest pyramidal structures, called ziggurats . In ancient times, these were brightly painted in gold / bronze . They were constructed of sun-dried mud-brick, and little remains of them. Ziggurats were built by the Sumerians , Babylonians , Elamites , Akkadians , and Assyrians . Each ziggurat was part of a temple complex that included other buildings. The ziggurat's precursors were raised platforms that date from

The Mesopotamians built

1804-583: Was 45 ft (14 m) in circumference. Circular stacks continued to the top. The structures were temples for the god Ala , who was believed to reside there. A stick was placed at the top to represent the god's residence. The structures were laid in groups of five parallel to each other. Because it was built of clay/mud like the Deffufa of Nubia, over time periodic reconstruction has been required. Pausanias (2nd century AD) mentions two buildings resembling pyramids, one, 19 kilometres (12 mi) southwest of

In the most prevalent version of the story, Cyparissus receives a stag as a gift from Apollo, which he accidentally kills with a spear while hunting in the forest. Cyparissus is overwhelmed by pain and sorrow, and asks Apollo to allow his tears to flow for eternity. Apollo transforms Cyparissus into a cypress tree, and

1892-487: Was limestone quarried locally and was cut to fit, not into freestanding blocks like the Great Pyramid of Giza. These structures were dated from pot shards excavated from the floor and grounds. The latest estimates are around the 5th and 4th centuries. Normally this technique is used for dating pottery , but researchers used it to try to date stone flakes from the structure walls. This launched debate about whether or not these structures are actually older than Egypt , part of

1936-529: Was usually made of limestone, granite or basalt and some were plated with electrum . Ancient Egyptians built pyramids from 2700 BC until around 1700 BC.
