Jezero

Jezero is a crater on Mars in the Syrtis Major quadrangle, about 45.0 km (28.0 mi) in diameter. Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. The lake in the crater was present when valley networks were forming on Mars. Besides having a delta, the crater shows point bars and inverted channels. From a study of the delta and channels, it was concluded that the lake inside the crater probably formed during a period in which there was continual surface runoff.
In 2007, following the discovery of its ancient lake, the crater was named after Jezero, Bosnia and Herzegovina, one of several eponymous towns in the country. In most Slavic languages, the word jezero means ‘lake’.
