Lumps of bog iron found in farm field adjacent to wetland area. Irregular masses of "limonite" (up to 6 inches diameter) were found on the ground surface of plowed field. Verified as goethite via XRD. Surficial geology of the area is a thick sequence of glacial outwash, predominantly sand and gravel. No active spring is currently precipitating bog iron at this location, so bog iron formed at some time after glacial retreat approximately 10,000 years BP. Prather farm refers to previous owner of property at the time of discovery of the nodules in 1978, when the field was rented and farmed by my father.
