Impact Craters
The largest of the seven craters on the reserve has a diameter of about 100 metres, and is about 11 metres deep. Five of the craters, including the largest, contain lakes. The date of formation is estimated to be about 5,000 years ago (Holocene).
The first meteorite found at Morasko was uncovered in 1914 by German soldiers working on the construction of a military fortification. Since then, many further fragments have been found, including one weighing 78 kg in 1956.
In September 2006, Krzysztof Socha, a meteorite-hunter from Kielce, working for the Geology department of the city's Adam Mickiewicz University, uncovered with the aid of a metal detector a meteorite which, after the removal of the dirt which covered it, was found to weigh 164 kg. This was the largest meteorite discovered in Poland. Analysis showed that the meteorite contained, apart from iron-nickel alloy, a small quantity of silicates (pyroxenes) not occurring on Earth.
In October 2012, a meteorite weighing about 300 kg was recovered from a depth of 2.1 m.
Currently, Adam Mickiewicz University is considering founding an educational centre, in order to draw attention to the reserve and the subject of meteorite discovery.

Famous quotes containing the words impact and/or craters:
“One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
—Joshua Meyrowitz, U.S. educator, media critic. “The Blurring of Public and Private Behaviors,” No Sense of Place: The Impact of Electronic Media on Social Behavior, Oxford University Press (1985)
“Listen.
We must all stop dying in the little ways,
in the craters of hate,
in the potholes of indifference....”
—Anne Sexton (1928–1974)
