Kaali Lake, Estonia

Ive written about Saaremaa before, but this Estonian island doesnt cease to amaze me,

This time im presenting you Kaali, which is a group of 9 meteorite craters. Formed in the 7th century BCE, it is one of the most recent craters created by an impact event and the only known major impact event that has occurred in a populated area.
The crater on the card is referred to as the main and the biggest one.

And to my liking, some mythology interfering too!

One day a young man stepped up to the God of Sun and claimed that he was Phaeton, the son of the God of Sun himself and an earthborn woman Klymene. The young man had doubted his high parentage and demanded affirmation. The God of Sun admitted it, and, as an affirmation, promised to carry out his fondest wish. The boy, who had often admired sun disc's journey across the firmament, uttered an unexpected wish: he wanted to drive the sun chariot across the sky.

Hearing that, the God of Sun regretted his easily given promise. He tried to persuade the youngster to wish for something else, but without success. The boy, taking no heed of the menaces he was told about, had his will. At first the drive came off quite well and Phaeton felt himself almost the lord of the sky. But then the things took a tragic turn: the spirited horses, feeling that the reins were in weak hands, became frisky and sheered from the right direction. The youngster lost power over the horses, who now dashed up to the skies, now turned right down to the Earth so that forests and fields there caught fire, rivers and fountains evaporated and dried out.

When the cries and lamentations from the Earth reached Jupiter's ears, the latter, in this emergency, seized his lightning bolts and punished the irresponsible charioteer. The blazing Phaeton shot through the air and fell on the Earth into the mysterious river of Eridanos, which no mortal eye has seen. Phaeton's sisters Heliads, daughters of the God of Sun, Helios, sought out their brother's grave to bemoan him there. The mourning sisters were turned into poplar trees on the banks of Eridanos
