Hier habe ich noch einen Artikel gefunden, der auf die globale Existenz der Cart Ruts hinweist und die menschliche Entstehung vorschlägt. Es ist doch verwunderlich warum man nicht einmal in Erwägung gezogen zu haben scheint, dass hier einfach Regenwasser am Werk war.http://www.azer.com/aiweb/categories/magazine/ai103_folder/103_articles/103_cart_ruts.html
Some of the most mysterious and puzzling ancient monuments found in Azerbaijan are cart ruts - that is, parallel grooves or channels carved directly into the rock, looking much like an ancient roadway. They're such an enigma. One can't help but wonder what purpose they served. How were they cut out of the surface of the rock? When? Why? No one knows for sure, and there seems to be very little evidence available to make any sort of judgment.
In Azerbaijan, these cart ruts vary in depth from about 5 to 50 cm. The depth of each rut depends on the relief of the rocky surface. Two or three ruts (or, in one case, as many as five) run in parallel to each other, generally about 1.5 meters apart. The ruts are clearly manmade. Sometimes they extend for up to 100 meters; however, we don't know which portion of the cart ruts we're looking at, whether it's the beginning, middle or end. Perhaps these tracks even continue down into the Caspian Sea.
Surprisingly, similar cart ruts have been found in the Mediterranean region, in places like Malta, Greece, Italy and southern France. They are particularly well developed at Pompeii and in Malta, where they have become tourist attractions. Archeologists hypothesize that the cart ruts date back to the Neolithic Age (10,0008,000 B.C.) or Early Bronze Age (50004000 B.C.) and reflect a high level of human activity in those regions. These ruts may even predate the invention of the wheel. Some archeologists suspect that by the time of the Roman Empire, these cart ruts had already fallen out of use. One popular hypothesis is that the cart ruts were used specifically to transport limestone blocks. The base of the rut may have been lubricated, enabling a sledge to be dragged from a quarry to a building site.
In comparison with the European cart ruts, the cart ruts found on Azerbaijan's Absheron Peninsula seem to be much better preserved - at least, up until now. Due to the peninsula's geography and climactic conditions, such as the perpetual sea breeze, they have been protected by a thin layer of soil.
In order to learn more about the Absheron cart ruts, we contacted Dr. Joseph Magro Conti, who confirmed that they are basically unknown outside of the Mediterranean region. Finding them here in Azerbaijan is highly significant and clearly begs an explanation. While the importance of the cart rut site in Absheron has yet to be realized, we would not be surprised if it eventually becomes a national treasure and tourist attraction and perhaps even becomes registered with UNESCO as a World Heritage Site.
For that to happen, however, the cart ruts must remain intact. A nearby surface quarry has been steadily encroaching on this area, cutting out limestone blocks for building construction at an alarming rate. Fortunately, after becoming aware of the impending danger to these ancient monuments, Husein Baghirov, Azerbaijan's Minister of the Environment and Resources, intervened and directed the Ministry's department responsible for Nature Use Regulation to stop the quarry's activity near the ancient site. Otherwise, within a very short period of time, uncontrolled quarrying would have destroyed the last few remaining cart ruts in this part of the world."
