On the Seabed of Tethys Ocean

Eye of Tethys: Crystal salt rock.

A story that a rock salt crystal told me and wise old sea shell agreed:

Long, long time ago, long before the ancient times, even before the first human being on earth, even before the first primat on earth, even before the jurassic, in the times when there were no Mount Everest, no Mount Ararat, even before the continents were separated into their current configuration, Pangaea was the supercontinent that existed during the Paleozoic and Mesozoic eras about 250 million years ago.

During the Triassic, a new ocean began forming in the southern end of the Paleo-Tethys Ocean. A rift formed along the northern continental shelf of Southern Pangaea (Gondwana). Over the next 60 million years, that piece of shelf, known as Cimmeria, traveled north, pushing the floor of the Paleo-Tethys Ocean under the eastern end of Northern Pangaea (Laurasia). The Tethys Ocean formed between Cimmeria and Gondwana, directly over where the Paleo-Tethys used to be.

Today, India, Indonesia and the Indian Ocean cover the area once occupied by the Tethys Ocean, and Turkey, Iraq, and Tibet sit on Cimmeria. What was once the Tethys Sea has become the Mediterranean Sea. Other remnants are the Black, Caspian and Aral Seas via a former inland branch known as the Paratethys Sea.

Most of the floor of the Tethys Ocean disappeared under Cimmeria and Laurasia. Geologists like Suess have found fossils of ocean creatures in rocks in the Himalayas, indicating that those rocks were once underwater, before the Indian continental shelf began pushing upward as it smashed into Cimmeria. We can see similar geologic evidence in the Alpine orogeny of Europe, where the movement of the African plate raised the Alps. And I found this fossil shell on the hills of Central Anatolia near Ankara:

The three largest salt lakes in the world are the Caspian Sea, Aral Sea, and Lake Balkhash. Tuz Gölü, Salt Lake is the second largest lake in Turkey and is located in the Central Anatolia Region, between Konya and Ankara. Other remnants are the salt caves in Central Anatolia. Türkçe

Gümüsler Monastery at Cappadocia

The monastery is located in Gümüşler town, an important historical source with relation to the middle ages. Despite not knowing the precise foundation of the Gümüşler Monastery, it is supposed to have been built between 8th and 12th centuries. The monastery is carved out of a large rock church and is one of the best preserved and largest of its kind in the Cappadocia region.

Life inside Turkish nomad tent home: Yurt

A yurt is a portable, bent wood-framed dwelling structure traditionally used by Turkic nomads in the steppes of Central Asia. The structure comprises a crown or compression wheel (tüýnük) usually steam bent, supported by roof ribs which are bent down at the end where they meet the lattice wall (again steam bent). The top of the wall is prevented from spreading by means of a tension band which opposes the force of the roof ribs. The structure is usually covered by layers of fabric and sheeps-wool felt for insulation and weatherproofing.

The word "yurt" comes originally from a Turkic word referring to the imprint left in the ground by a moved yurt, and by extension, sometimes a person's homeland, kinsmen, or feudal appanage. The term came to be used in reference to the physical tent-like dwellings only in other languages. In modern Turkish the word "yurt" is used as the synonym of homeland.

Autumn Forest at Seven Lakes

The nature begins to change in Autumn, always in perfection. While quietly preparing to winter, the chirping of the spring, merry laughter of the birds, and sounds of streams full of enthusiasm are reduced gradually; leaving the place to the sound of the wind and rain, again. Green trees take on different colors according to their types in every fall. Each color has a thousand and one tones and shades. Millions of trees are preparing for winter in Seven Lakes region, in another poetry, in another autumn.
