Bovbjerg cliffs in the Vestjylland UNESCO Global Geopark (Photo: UNESCO) Due to the impact of the COVID-19 pandemic, countries that did not apply for new geopark recognition, the UNESCO Global Geopark Council decided to consider this year’s candidates from Old application form (period 2017-2019). In fact, evaluations of these geopark have been carried out since before the start of the pandemic. The management boards of these parks have also submitted additional information reports as requested by the Council. The new UNESCO Global Geopark is: 1. Vestjylland Global Geopark, Denmark About a third of the Geopark’s surface area is on the mainland, with the rest comprising marine areas in the Limfjord and the North Sea. The terrestrial part of the Geopark’s icy landscape are flat plains, lagoons and lakes formed by successive ice ages, especially the most recent ice age, Main Advance, took place 23,000 to 21,000 years ago. Wind and water are continuing to affect the landscape in very conspicuous ways. Geopark includes 13 areas Naruta 2000, 5 nature reserves and wildlife and more than 90 natural geological sites. Natura 2000 is the European Union’s ecological network, which includes important bird habitats and protected habitats that are important to other wildlife species of interest to the European Union. 2. Global Geopark Saimaa, Finland Geopark takes its name from Lake Saimaa, the largest lake in Finland and the 4th largest lake in Europe. Located in southeastern Finland, south of the Vuoksi water system, the Geopark stretches about 20 to 180 meters above sea level. One-third of the park’s 6,063 km² of surface area is water, dotted with thousands of islands, and a coastline of more than 8,000 km. The rocks of Saimaa point to the area’s as far back as 1,900 million years ago when it was part of the seabed. The rocky bedrock is formed over time when the sea water recedes, mountain folds take place, the rocks crystallize into gneisses and granite. The ancient foundation was further affected by the ice age, and land accretion continues to this day. The land of this area was formed in the past 20,000 years due to erosion of ice sheets. Since then, several unique and endangered species, including seal Saimaa and salmon, have been “isolated” in the area. Impressive stone paintings on the shores of the lake show human presence from the Stone Age. The location and features of the Geopark allow visitors to observe the patterns of ice lobe formation in Finland’s Lake District.

Thuringia Inselsberg Global Geopark – Drei Gleichen, Germany Located in Thuringia, central Germany, the Geopark covers an area of ​​about 988 km² at an altitude of 250 to 900 meters above sea level. The park’s geology records more than 150 million years of Earth’s history, from the merger of the Pangea supercontinent to the dissolution of the continent during the Late Triassic. Geopark’s distinctive fossil profile has been a subject of study for over 300 years, leading to the accumulation of great geological expertise. The fossilized reef here, among the first recognized in the 19th century, is a remnant of the formation of a small island surrounded by coral reefs in the Zechstein Sea. You can explore three of the Geopark’s hundreds of natural caves. The park’s Geo & Pleasure geo-tourism trail highlights the link between soil and local geology and traditional indigenous cuisine in the low mountains and loess regions.

Grevena Global Geopark – Kozani, Greece In the North of Greece, in the Western Macedonia region (within 40-70 km of the border of Albania and North Macedonia), this geopark covers an area of ​​2,486 km², with an altitude of 380 to 3,800 meters above water level. sea. Greece’s longest river, Aliakamon, flows through Grevana – Kozani. The park’s geology includes rock formations dating back to about a billion years ago, to date records a number of tectonic plate events, including the birth of the Tethyan Ocean and the emergence of Europe. as a separate continental block. Orliakas Mountain, a reef in the midst of an ancient African-European contiguous area, inside the Geopark. Studies of these geological features have significantly contributed to the development of popular theories about the origin of tectonic plates. The geopark also houses some of the world’s most important tornado fossils, The Land of Elephants and Mammoths with the longest known tusks in the world (over 5 m).

Global Geopark Belitong, Indonesia Belitong Geopark is located about 400 km north of Jakarta, including Belitung Island and more than 200 small islands in 13,000 km² of waters. The marine area accounts for about 2/3 of the total surface area of ​​this park. Belitong is known for its spectacular Tor granite landscape, and large rock outcrops, created by weathering and erosion. The park also features a rare meteorite tektite called Satam or Billitonite, along with unique mineral deposits such as the Nam Salu primary tin mine, the richest single tin mine in the region. Southeast Asia. Located on historic maritime trade and migration routes, Belitong is home to more than 288,000 people from diverse cultures, including the Sawang Tribes. The main sources of income are agriculture, fishing and mining. (Photo: Belitong Geopark / UNESCO) 6. Aspromonte Global Geopark, Italy Located in Calabria, southern Italy, with an altitude of nearly 2,000 meters above sea level, Aspromonte Geopark is home to more than 273,000 people. The site’s exceptional geology is the result of the evolution of geodynamics and seismics that began more than 500 million years ago and are still ongoing. This geopark is located on a peninsula along the Apennine Mountains, corresponding to a piece of the Alpine range separating Spain, northwest Italy, Sardinia and Corsica. A complex of mountains, ridges and plateaus interspersed with deep valleys created by unique natural water currents, has “sculpted” the hard rocks of the foundation, leading to metamorphism to crystallize over time. and create spectacular waterfalls. The Geopark’s unique geomorphology gives visitors a stunning 360-degree view of the Strait of Messina, Mount Etna, the Aeolian Islands, Calabrian Greek territory, Locri territory and Gioia Tauro Plains.

Majella Global Geopark, Italy Located in the Center of Apennines, the Geopark has a surface area of ​​740 km² with an altitude of 130 to 2,800 meters above sea level, along with more than 60 peaks in the Majella Mountains, half of which are over 2,000 meters high, like Mount Amaro. The geopark is made up of a series of gorges, many rivers and a number of perennial lakes that are essential to wildlife. This area is made up mainly of fossilized limestone. With ruins associated with the human presence some 600,000 years ago, the Geopark has 95 geological sites, including one of the oldest archaeological sites in Europe. Most have considerable educational and tourism value. Thanks to the special landscape of high-altitude reliefs near the sea and the heterogeneity of geomorphology, the Geopark is characterized by a variety of microclimate, ecosystems and ecological niches, which has increased the level of special and valuable biodiversity.

Public mountain geology Holy Cross, Poland Located in the southeastern part of Poland, the western part of the Świętokrzyskie mountain range, the Holy Cross Mountain Geopark is 200 to 400 meters above sea level, and is home to more than 252,000 people. The Geopark located in the Trans-European Garment Region (TESZ), a major tectonic boundary between the Variscan Western Foundation, the Pre-Cambrian Eastern Foundation and the reproductive belt of Alpine structures, is the key to Learn the geological structure of Europe. More importantly, this is the only site in the TESZ where sedimentary rocks representing the sequence of all geological periods from the Cambrian to the Quaternary are raised on the surface. The geology of the park, combined with human intervention over the centuries has resulted in a rich diversity of landscapes, flora and fauna. Traces of human activity in the Geopark date back 60,000 years, including Neanderthal camps and a beautiful cave system. Many ancient quarries are testament to the importance of mineral deposits, metal ores, limestone and other natural resources to local people over time.

Inside Krizna jama, a place for tourists traveling by boat. Photo: National Geographic Where the rivers mysteriously disappeared With 20,271 square kilometers and 2 million inhabitants, Slovenia provides the world to more than 20 famous caves out of more than 8,000 karstic formations called jamas. Here, it is easy to see with the naked eye the majestic rivers suddenly mysteriously disappearing into the ground, then forming the system of underground paths through the limestone mountains forming caves. There are also traces of cave dwellers of nearly 5,000 years ago, autographs of an expedition in 1557 left on the cliffs of Krizna cave, and since then cave tourism in Slovenia has flourished. from the seventeenth century. Krizna jama, birthplace of cave exploration. Exploration of karstic limestone caves is very dangerous, even with taking pictures in a world completely different from space under the sun. Robbie Shone, British photographer and cave researcher, spent 10 years taking pictures of Kacna caves. The window entry was 250 feet (250 feet) higher than the ceiling, and an additional 250 feet was added to the underground river, the common pillar with up to 500 free-fall, up and down thanks to ropes and lifters. The key to the Slovenian cave system lies in the rivers, when hidden when present, the most famous of which are the rivers Reka, Rak, and Pivka. River caves are not uncommon, however, there are only some karst landscapes where river caves reach as vast as in Slovenia. The karst plateau forms a special geographical area here, it extends from the Adriatic coast in the south to the Vipava Valley, forming a corridor connecting the limestone regions of northeast Italy. Beneath the village of Škocjan are caves of the same name, a UNESCO heritage site, in which an entire river – the river Reka – seems to be swallowed up by the earth. From the ground, the river suddenly plunged into a straw (siphon) in the rock, continuing to winding along underground currents, then emerged 24 miles away near Italy’s Monfalcone before joining the Timavo River into the sea. Adriatic. Where people live with caves More than anywhere, Slovenia is not only the birthplace of the cave tourism industry, but also a place of symbiosis between people and a special geological structure. The Italians and Slovenes living along the limestone corridors have created a unique Teran grape for the famous iron-rich red wine. Caves have played many roles throughout history. They used them as a source of water, a refrigerator, and even an ammunition storage room during the war. During the Ice Age, Krizna jama was an important bear sanctuary – some 2,000 bear skeletons remain. Today, river caves are important habitats for many species of animals, some of which are endangered. Postojna jama is Slovenia’s largest and most touristy cave, complete with trains that take you through tunnels and fossil-filled labyrinth halls and pristine caves. pretty. Nearby Postojna and Planinska jama are home to the proteus anguinus, an endangered species of underwater cave salamander affectionately known as the “human fish”. During Christmas, a scene of the Child God was erected in Postojna and more than 500 people gathered in a stone hermitage to witness a festival performance staged between stalactites and stalagmites. Postojna jama is completely designed with trains taking tourists through the tunnels … Photo: postojnska-jama.eu Here you can choose the right level of cave travel for you. The Postojna Cave is considered the largest jade, where the cave train will take visitors to magnificent sculptures, stalactites, stalagmites and halls. The beautiful Škocjan Cave is on the UNESCO World Heritage List. Here you can see the deepest and largest underground gorges in the world. And more than that, behind the cave doors is a place for travelers who have a lot of courage to explore. Krizna Cave impresses with a series of emerald green underground lakes, on which visitors can sail to magnificent limestone halls under the safety guidance of experienced explorers. The birthplace of cave exploration The history of cave exploration is associated with Krizna jama located in the Cerknica Polje limestone belt near the Loz settlement. The length of the cave is up to 8,273m, of which about 600m is arranged for regular tours of tourists, the rest is for explorers. In fact, Krizna is considered one of the most attractive tourist caves in Slovenia, due to the large underground lakes with clear water formed after dams of quartz stone and decorated in various styles. way by rolling rocks. One of the tourist attractions is the bear cave. Currently, Krizna jama is under the management of the Krizna Cave Caving Society, and is here by guided boat travel. The first inscription of the Krizna expedition engraved on a cliff, in 1557. Krizna’s original name was Loz Cold Cave (Mrzla jama pri Lozu), changed to Cold Cave under Mount Krizna (Mrzla jama pod Krizno goro), and now takes the name of the Cross Church located on the hill given to the cave system. , called Cerkev Svetega kriza. The first inhabitants of Krizna cave were in the metallic era with many relics including pottery, but their ancestors lived in caves belonging to the Paleolithic period, around 2,800 BC. Perhaps this was the reason why the Krizna expeditions were so intriguing, and the expedition’s first autograph inscribed on the cliff 1557. The expeditions continued through the centuries as a kind of discovery tourism. , but it was not until 1832 that an official report was produced by JJ Tobin, and in 1838 J. Cerar provided the first descriptive sketch. The discoveries weren’t really easy, and it wasn’t until 1962 that a group of high school students from Ljubljana Šiška crossed the first lake under the guidance of Professor Prezelj. Explorers from Slovenian and foreign clubs spent decades, from 1970 to 1990 searching, discovering new cave passages and halls, and especially diving to survey pipes. suction of the Kittlow well. Measurements, surveys and expeditions were promoted between the 1990s and 2003 through the Speleological society of Karlovec and the Assotiation of Krizna cave lovers. They began cleaning the caves, photographing it, and discovering new tunnels with deep diving, searching for new straws. And today, cave tourism has become a unique economic activity in Slovenia.
