The glacial till makes it harder to place. It could have come from anywhere!

more info on rock
by: Mike

Thanks for posting Douglas!

Some more info on the geology of the area - the rock was found in a limestone plain (just outside of Napanee, in south-eastern Ontario), and the soils here consist of glacial till.
