    Some call it the “City of 1001 Churches” and some know it as the “City of 40 Gates:” the now-abandoned medieval city stands on a lonely plateau in Armenia, 45km away from Kars, Turkey.

    Founded more than 1,600 years ago, Ani stood on various trade routes and its many religious buildings, palaces, and fortifications were amongst the most technically and artistically advanced structures in the world. The blame for its ruin lies in the hands of many: vandals, looters, Turks, Mother Nature herself, poor restorations and inept archaeologists.

    Long ago renowned for its splendor and magnificence, Ani was sacked by the Mongols in 1236 and devastated in a 1319 earthquake, after which it was reduced to a village and gradually abandoned and largely forgotten by the seventeenth century.

    Rediscovered and romanticized in the 19th century, the city had a brief moment of fame, only to be closed off by World War I and the later events of the Armenian Genocide that left the region an empty, militarized no man’s land.

    Ani is a widely recognized cultural, religious, and national heritage symbol for Armenians. According to Razmik Panossian, Ani is one of the most visible and ‘tangible’ symbols of past Armenian greatness and hence a source of pride. All the structures at Ani are constructed using the local volcanic basalt, a sort of tufa stone. It is easily carved and comes in a variety of vibrant colors, from creamy yellow to rose-red, to jet black.

  • Meet the Nazca Runways: Flat Mountaintops that defy explanation | Ancient Code

    Fonte: Meet the Nazca Runways: Flat Mountaintops that defy explanation | Ancient Code

     

    The giant flat Mountaintops at Nazca have remained a profound mystery for decades. Even today, archaeologists are unable to explain how and why ‘ancient man’ created massive, flat ‘runway-like’ marks thousands of years ago.

    Giant Ancient Alien Runways at Nazca
    One of the World’s Greatest Mysteries. What happened to the mountain tops in Nazca, Peru?

    We have all been fascinated by the Nazca and Palpa lines for decades. These incredible pieces of ancient ‘art’ are located in the arid Peruvian coastal plain approximately 400 kilometers south of modern-day Lima. The staggering geoglyphs cover around 450 kilometers and were created on the arid floor sometime between 500 BC and 500 AD.

    The Nazca and Palpa lines are considered one of archaeology’s greatest mystery, mostly because of their size, quantity, and nature. Some of the lines depict living creatures, stylized plants, and imaginary beings, as well as geometric figures several kilometers long.

    According to studies, the largest of the Nazca figures is approximately 1000 feet, and the longest geoglyph goes on for around 9 miles.

    However, the most mysterious discoveries at Nazca are the enigmatic mountain tops that eerily resemble modern-day runways. The mountaintops of some of the surrounding mountains at Nazca look as if something literally pressed down —with incredible force— the top of the mountain. Many researchers have said that the mysterious mountaintops look as if something managed to ‘perfectly’ cut through the mountaintop, creating incredible flat surfaces.

    So how is it possible that these giant ‘runway-like’ mountains even exist? And if the Nazca are known for having created the incredible desert-art, intricate figures of animals, plants and geometric shapes, why would they even bother and create these huge flat surfaces?

    Nazca Airport

    There are numerous questions that remain unanswered at Nazca. Were these giant figures meant to be seen from above? Do they mimic constellations in the sky? What were the ancient’s trying to say to future generations? Were the Nazca lines mere ancient art? If so… why would ancient mankind create art that cannot be fully appreciated from the ground?

    Is it possible that –as Ancient Astronaut theorists suggest– the ancient ‘runways’ seen at Nazca are in fact navigational markers used by advanced extraterrestrials that visited the area thousands of years ago? And is it possible that some of the giant, flat triangles were created by massive spacecraft that touched down in the distant past? What if the ‘gods’ used these paths in the distant past to visit the people in Peru? And what if, ancient people created figurines such as the Nazca Astronaut in honor of those “gods” who came from above?

    Nazca Airport 2

    Interestingly, according to some local legends, the mysterious Incan creator god Viracocha commissioned the Nazca Lines and glyphs in the past. These lines are said to be created by the Viracocha himself. He was the great teacher God of the Andes.

    THE VISIT

    Timor-Leste is perhaps best known recently for conflict, dry savannas, and increasingly hyper-diverse coral reefs. However, one of the most different, most diverse but least known habitats is the Cloud Forests that occurs on some of the mountains. Approximately 100 km2, and definitely <200 km2 of Timor-Leste (area 15,007 km2) is Cloud Forest, so c.0.67% or 1.3% of the land-cover of the nation. Although highly distinctive and rich and endemic plants, birds and land-snails, Cloud Forests in Timor-Leste have not had a high conservation profile.

    Timor Island was broadly created as a result of a collision between continental Asia and continental Australia, and is thought to have been above sea (popped out of the sea) approximately 4.5 million years. The oldest part of the island are the high mountains, being pushed up at a more or less equal rate. These high mountains were once the only parts of Timor above sea.

    During 12-17 June 2015 Mario Soares de Carvalho, Zemally Dejesus and I visited the Mt Taroman area with the aim of documenting natural values, particularly birds. Mt Taroman is a c. 20 km2 area of montane Cloud Forest within the elevation range of 1,000-1,730 m. It is in Suai Municipal (District) across several villages including Fatululik and lies only a few km from the Indonesian international border.

    We observed birds and made sound-recordings, made acoustic recordings of micro-bats, actively searched for reptiles and landsnails and took photographs of Cloud forest habitats and some plant species.

    WILDLIFE SIGNIFICANCE AND THREATS

    A total of 53 bird species (40 “forest-specialized” bird species; 23 globally restricted-range species; one globally endangered species; 11 hill-montane bird species); one native land mammal; six insectivorous microbats including Canut’s Horseshoe-bat Rhinolophus canuti, one species of Eremiascincus “Montane” skink, an invasive Black-spined Toad (Duttaphrynus melanostictus), and a likely undescribed landsnail similar in appearance to Parachloritis manuelmendesi.

    We recorded 25 bird species in Fatululik village (c.1,000 m elevation), 43 bird species around our camp (1,530 m), 16 bird species between 1,600-1,700 m, and 21 bird species above 1,700 m near the summit. The reduced richness in the number of bird (and many other species) is a well-known global pattern. Mt Taroman is relatively large area (c. 20 km2) – perhaps 20% or more of the remaining Cloud Forest in Timor-Leste – though many forest areas are fragmented and occur in small patches. It is one of the most biologically rich montane areas in Timor-Leste, similar to the better known Mt Mundo Perdido near Ossu.

    The Key Threat to biodiversity in the Taroman area is relatively intensive free-range grazing by livestock, especially cattle – 100s of animals are present on the mount. This results in soil erosion, slumping (hill slope erosion), likely reduced water quality, obvious damage to tree roots in forest, and greatly reduced or absent forest regeneration as palatable plants within reach are eaten. Mitigating this impact is not impossible, because studies in Timor-Leste have already shown the economic benefits of penned-livestock. Higher quality feed to penned livestock creates larger and healthier stock with greater sale value.

    A clear Win-Win for nature and for rural livestock graziers.

    CLOUD FOREST HABITAT

    We did not survey the flora of Mt Taroman but estimate that there may be 300-500 plant species. We did see Dacrycarpus imbricatus (Family Podocarpaceae – the Southern Hemisphere Conifers) – generally the largest tree in montane forest, growing up to 30 m tall in Cloud Forest; perhaps around 50 ferns including King Fern Angiopteris evecta (Family Marattiaceae), tree-ferns, filmy-ferns and numerous ground and epiphytic ferns. The moss and lichen flora is also probably quite species-rich, but have been very poorly-sampled on Timor Island in general.

    CAMP AND PEOPLE SHOTS

    We visited in mid-June towards the end of the wet season, but there was still some rain, and cloud and mist for several days. It was also quite windy, with weather rapidly closing in from clear sunshine to misty rain in a matter of moment. We camped at the edge of forest at 1,530 m, a few hundred meters from a massive limestone outcrop, and about 500 m from “Game of Thrones” rock, a stunningly eroded set of limestone knives on another outcrop.
