    How do I identify a possible Lake Ontario glacial erratic?

    The bolder in the attached iphone image was located just offshore in Chaumont Bay on the eastern shore of Point Peninsula. It was sitting in about 5 feet of water and was interfering with the boat dock, so it was hauled ashore. It is roughly 1 meter long, appears to be metamorphic, and has a reddish color. It doesn’t look anything like the surrounding flat greyish lake bottom rock. Does this look like a glacial erratic? Are there any simple tests to determine the makeup and possible origin of this rock if it is in fact a ‘visitor’ from Canada?
