Kaali crater, Saaremaa island, Estonia

Kaali is a group of 9 meteorite craters located in the village of Kaali on the Estonian island of Saaremaa.
At an altitude of 3 to 6 miles, a meteor broke into pieces and fell to the Earth in fragments, the greatest of which produced a crater with a diameter of 360.9 feet and a depth of 72.2 feet. The explosion removed huge amounts of dolomite and other rocks and formed a very tall and extremely hot gas flow. Vegetation was incinerated up to 3.5 miles from the impact site.
The impact is thought to have happened in the Holocene period around 3,500 years ago. The estimates of the age of the Kaali impact structure provided by different authors vary by as much as 6000 years, ranging from 6400 years to 400 years BCE.
Kaali järv (Kaali Lake) is on the bottom of this crater. A further 8 smaller craters are also associated with the meteorite impact. Their diameters range from 39 to 131 feet and their respective depths vary from 3.3 to 13.1 feet. They are all within 0.6 miles of the main crater.
