Lough Tay, Ireland

The Lough Tay, located in the Wicklow Mountains, about 50 km south from Dublin, is also known as the Guinness Lake due to its shape and colours.

The white sandy beach on the northern coast makes the Guinness foam. The brown colour of the water close to the beach (due to the water coming from the streams that rise on peat covered uplands) complete the incredible visual similarity to the famous Irish pint.

You can see the lake from the R759 scenic route, or if you want a better view from the top, take the walking trail towards the Luggala mountain (accessible from the R115 — the best scenic drive in the Wicklow mountains) or the Djouce mountain, one of the most spectacular walks in the Wicklow Mountains, from which you can see the whole Dublin bay and, on a clear sky day, also the Welsh coastline.

The Lough Tay beach was chosen in 2013 as the set for the village of Kattegat in the Vikings tv series.

Impact Craters on Earth

Impact craters on earth are difficult to preserve due to the continuous remodelling of the earth’s crust by orogenesis, plate tectonics and atmospheric agents.

There are around 180 recognizable impact craters on earth, of which about 60 are now buried under sediments, a considerably lower number, for example, compared to the 360.000 craters on Mars or the 7.000 on the moon.
This thanks to the shield made by the earth’s dense atmosphere.
 
Some of them have caused catastrophes, such as the meteorite that carved the Chicxulub crater in Mexico: according to the theory currently accepted by the scientific community postulated by the physicist Luis Álvarez and his son geologist Walter Álvarez, is widely thought to have caused 65 million years ago the end of the dinosaurs due to a tsunami and dust emissions which totally covered the earth’s surface a cloud of dust for many years.


Others have instead brought wealth as the
Popigai crater in Russia, whose impact transformed graphite into diamonds within about 13 km radius.

List of the biggest impact craters on earth:

1. Vredefort Dome, South Africa: 160 km diameter, 2.02 billion years old.
2. Chicxulub crater, Mexico: 150 km diameter, 65 million years old. 
3. Sudbury crater, Canada: 130 km diameter, 1.85 billion years old.
4. Popigai crater, Russia: 100 km diameter, 35 million years old. 
5. Manicouagan crater, Canada: 100 km diameter, 214 million years old.
6. Acraman crater, Australia: 90 km diameter, 580 million years old.
7. Chesapeake Bay crater, USA: 85 km diameter, 35 million years old.
8. Morokweng crater, South Africa: 70 km diameter, 145 million years old.
9. Kara crater, Russia: 65 km diameter, 70 million years old.
10. Beaverhead crater, USA: 60 km diameter, 600 million years old.

Loktak Lake, India

 

Also known as the Floating Lake, the Loktak Lake, located in Bishnupur district of Manipur, about 50 km south of the city of Imphal, is the largest freshwater lake in North-Eastern India.

With a surface of 290 square kilometres, it is famous and unique for its floating islands named phumdis: masses of soil, organic matter and vegetation that hosts several species of animals and aquatic plants including the Sangai, a brow-antlered deer, state animal of Manipur.

Part of the lake houses the Keibul Lamjao National Park, the world’s only floating national park.

Barrancos de Gebas, Spain

Located in the southeast of Spain, between the city of Murcia and the Sierra Espuña Regional Park, the Barrancos de Gebas is one of the most fascinating landscapes in Spain.

The semi-desert area, reminiscent of the American badlands, has a lunar landscape characterized by spectacular gullies, canyons and the turquoise waters of the Embalse de la Rambla of Algeciras.

Russian Seven Wonders

As written by the historian Herodotus (450 b.C.), the ancient list of the Seven Wonders of the World was formed by:

Colossus of Rhodes
Great Pyramid of Giza
Hanging Gardens of Babylon
Lighthouse of Alexandria
Mausoleum at Halicarnassus
Statue of Zeus at Olympia
Temple of Artemis at Ephesus

The only still existing wonder is the Great Pyramid of Giza, the other wonders were destroyed by the time and the human’s hand.

In 2007, the New Seven Wonders of the World list was declared after an initiative by the Swiss corporation New7Wonders Foundation:

Great Wall of China
Petra, Jordan
Christ the Redeemer, Brazil
Machu Picchu, Perù
Chichen Itza, Mexico
Taj Mahal, India
Colosseum, Italy
Great Pyramid of Giza, Egypt

In 2008, a curious initiative by the Russian newspaper Izvestia, Radio Mayak and a Russian television channel, determined The Seven Wonders of Russia:

Mount Elbrus


Mount Elbrus 

Volcano located in the western area of Russia, it’s the tenth most prominent mountain in the world and the highest Caucasian (5.643 m) mountain.
Mount Elbrus has two twin summits, whose ascent is accessible to all climbers, though,  according to many experts, it is considered dangerous because of its potential volcanic activity.

Cathedral
The Cathedral of Vasily the Blessed
Church located in the Red Square, Moscow, it’s now a museum, built from 1555 on orders from Ivan IV Vasilyevich “the Terrible” in commemoration of the capture of Astrakhan and Kazan.
The cathedral, since 1990 in the UNESCO World Heritage Site’s list, is one of the most famous Russians symbols.

Peterhof
The Peterhof Palace
Recognized as a UNESCO World Heritage Site and referred as the “Russian Versailles”, it is a series of outstanding palaces and gardens located in Saint Petersburg, built in 1714 on the orders of Peter the Great.

Mother Russia
Mamayev Kurgan
A memorial complex in the city of Volgograd commemorating the Battle of Stalingrad (World War II, 1942- 1943), built between 1959 and 1967. 

The complex is dominated by the Mother Russia statue (85 m high).

Geysers
The Valley of Geysers
Located in the Kronotskij Natural Reserve, Kamchatka Peninsula, this spectacular valley has one of the largest concentration of geysers in the world with hundreds of living geysers and hot springs.

Discovered in the 1950’s it is now a UNESCO World Heritage site; the valley, due to its instability, is often subject to geological disasters like the events in 2007 and 2014 that had hardly damaged the landscape.

Baikal
Lake Baikal
Formed more than 20 million years ago and located in the southern area of Siberia, it is the largest by freshwater, the deepest (1.642 m depth) and maybe the oldest an clearest lake in the world.

In 1996 the lake was declared a UNESCO World Heritage Site.

Manpupuner
The Manpupuner rock formations 

Also known as the Seven Strong Men Rock Formations, these seven gigantic (30-45 m high) stone pillars are located in the Pechoro-Ilychski Reserve, western Ural mountains.
The pillars have bizarre shapes formed through the effects of wind, rain, ice and snow.
