Topic: Meteorites Posted: 31-Jan-2007 at 12:30 |
What have been the most well known meteorites that have fallen (and created remarkable craters), and more exactly, how have they affected peoples' lives?
I can tell you for example, of Kaali crater on Saaremaa, Estonia; which is around 10,000 years old (plus, minus, a few thousand years). The crater was thought as a place where gods lived at and where people made sacrifices. (Although, I am not 100% sure in it all, but it was approximately like this).

Australia has many meteor craters, over 20 in fact. There are a couple well-known ones which are truly monumental in size. Wolf Creek: 900m across and the 'second most perfectly formed crater on earth'. Wolf Creek crater has a rim of about 25m, while the original deepest point is believed to be 150m. Used as a NASA training ground for getting a feel for moon craters. Located 130km south of Halls Creek, Northern Territory. Gosse's Bluff: Penetrating almost 600m into the ground origninally, the meteorite that created Goose's Bluff has now completely disappeared and its remnants are a huge 22km diameter crater, and at first, a giant mushroom cloud extending 20km upwards!

Yes it is Ikki, to be precise, 175km west of Alice Springs, Northern Territory. Pretty massive isn't it - just imagine the impact!
