FLÄSCH, GRAUSPITZ, 7306 TRIESEN, LIECHTENSTEIN
Unexploded non-detonated live 20yr mortar.
Later found out after showing this picture to the guy that just happened to be the man that's job is to TNT any found; which he had to do only 3wks ago. 20 years ago the Swiss Army would use this as training ground for firing mortars from other mountains in winter when people, cattle & life stock would move out after the summer
