These special rocks are Omarolluk or "Omar" stones that were formed on the Belcher islands in Canada's Hudson Bay and were later transported southwards by a glacier. Because scientists know precisely where they came from they are very valuable in documenting the movement of glaciers.
Their distinctive pits form because the rock that was in the pit (a carbonate concretion) dissolved.
These glacier erratics have been tumbled smooth and rounded in Lake Superior over millions of years until eventually washing up along the Michigan shoreline.
These rocks are absolutely cool. Each one is unique with dissolved out pits or hemispherical voids.
Unpolished and Natural, smoothed by the Michigan Great Lakes.
Dry pictures of both sides are shown.
