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 weighing 164 kg. At the time 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
The largest two fragments, the 30.8-ton Gancedo and 28.8-ton El Chaco, are among the heaviest single-piece meteorite masses recovered on Earth, along with the 60-ton Hoba and a 31-ton fragment of the Cape York meteorite.
