Friday, September 13 at 8:30 PM -- Metal Detecting: Joe Jorgensen and Peter Schichtel at Denny’s, 752 NJ-18, East Brunswick, NJ

Our two speakers will discuss their hobby of metal detecting and share some of their best finds. They will also share two of their most memorable sites searched, a paper mill "pulp dump," and a Civil War picket post near Gettysburg PA.There will be displays from both sites among other finds.

Joe Jorgensen: A 58-year-old resident of Pompton Plains, N.J.,Joe started in the hobby of Metal Detecting in 1973 ( 46 years ).He is the presi-dent of the East Coast Research and Discovery Association for 19 years, and he is a self-employed contractor. He's a past mayor of Pequannock Township, 2009.He collects coins, stamps, tools, bottles, etc.

Peter Schichtel: Peter was born and raised in North Jersey and spent his child-hood exploring the fields, streams, and woodlands in search of treasures and rarities. Metal detecting, bottle hunting, hunting for Indian Artifacts and gems were a few of his passions. He studied Archaeology and US history in CCM, Montclair State, and Uppsala College. His emphasis and point of study was the Archaeology of the Passaic River Basin in which, as an independent study, he located and mapped Indigenous sites that were originally listed by Dorothy Cross in the 1930s. He participated in the dig at the Parsippany Petroglyph Site, and the Passaic Basin digs in Essex Co. He’s an avid collector of Relics and historical items and, along with Joe Jorgensen, participate n lectures and displays at venues such as the NJ / NY Fossil and Gem Shop. As a frequent contributor of articles to American Digger Magazine, he was given the opportunity four years ago to write the American Indian Artifact column.
