Johnathon Larson was exploring Sashabaw Creek behind his house off Clintonville Road when something caught his eye.
‘It’s a rock, but it had a pattern in it,? Larson said. ‘I thought, ‘what’s this???
The pieces seem to fit together and are engraved with the letters ‘M? and ‘N.?
‘Our neighbor who grew up here thought it could be part of an old road sign,? said Maria Larson, his mother. ‘Why it would be way over here, we don’t know.?
Johnathon also found some old dutch dishes and old bottles in the creek. They plan on contacting Clarkston Area Historical Society for their insights.
Wherever they’re from, it’s a good lesson in Michigan history, said Maria, a former teacher.
