The approximate time of Kaali meteorite fall is 7500-7600 years ago.
Meteorite fall caused big damages on already inhabited Saaremaa, it could be compared to explosion of atomic bomb. At the height of 5-10 km meteorite fell apart and came down to the ground in pieces the biggest of which created a big crater with diameter of 110 m and depth of 22 m and 8 smaller craters. Interesting to know: Among the world's giant craters Kaali crater is on 8th place. Kaali field of meteorite craters on Saaremaa is the rarest nature wonder in Estonia, being at the same time the most spectacular in Eurasia.
Although it's interesting to know that this small crater was caused by a meteorite, the drive to get there wasn't worthwhile.
Estonia has several meteorite collision sites, apparently, and this is one. It clearly came from a meteorite strike if you understand what you're looking at, a perfectly round lake with heaped-up...
The place is peaceful and very green. Don't miss the art/handicraft shop in the white building. Or the other shops. Worth a visit all of them.
