Unusual Ground Marking - Definition

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 burned grass. At some Unusual Grund Markings it 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 sceptism most of them are fakes.
