General information

The Terby crater is located on the northern edge of the Hellas impact basin. It is named after the Belgian astronomer François J. Terby. In the northern part of the crater Terby there are a number of layered mesas, the valleys have significant gullies. These channels and the clearly recognizable stratification of the rocks suggest that water could have played a major role in the genesis of these landforms.

Crater overview

The crater has a diameter of 174 km. Its center is located at 28° South and 73° East.

Structure anomalies

Not only geological features indicate the importance of water in development of the landscape structure. Right here there is a system whose function is the delivery of ground water Through a duct system, the water was led in large basins. Noteworthy is not only the fact to find such a plant here, but that the whole architecture was designed, that figures (geoglyphs) can be seen from a great distance in the sky. Bemerkenswert ist allerdings nicht nur der Umstand, hier eine solche Anlage zu finden, sondern dass die Anlagenarchitektur so ausgelegt wurde, dass Figuren (Geoglyphen) aus großer Entfernung aus der Luft erkennbar sind.

Geoglyph at the water plant in Terby

With much effort, a technical solution has been devised, which also includes artistic, and aesthetic aspects.
