Unusual Ground Marking
Unusual Ground Markings or UGMs are named ground features that appear to be hard to explain. The best-known UGMS are crop circles.
Other forms of UGMs are ice circles , footprints of unknown origin and burnt grass. At some Unusual Ground Markings there is said to be a higher level of radioactivity.
Unusual ground markings are sometimes interpreted as landing traces of UFOs or as footprints from cryptozoological animals or aliens; while for sceptics most of them are fakes.
