In result of searching in the Morasko preserve for the documentary series Meteorite Men two irons were found below ground. A 544-g shrapnel-like with weak shock deformations, mildly weathered, at low depth, and 34-kg individual, with its upper surface 156 cm deep, with a thick shell of clay and weathering minerals. Of particular interest is presence of chukanovite, a mineral discovered in the Dronino iron meteorite. Morasko is the second meteorite, where chukanovite could be found. The recovery of a new specimen so much deeper than the previous depth record, suggests that further, more detailed surveys should be conducted in the future with improved metal detecting equipment. Moreover, the larger specimen was found embedded in a Miocene clay, which demonstrates that it fell from the sky at that exact spot and was not deposited in glacial terminal moraine.
