In 2006 a crew member of a mining exploration team working in the vicinity of Points North Landing, Saskatchewan, found a small carbonate rich glacial erratic that had been chewed by rodents. The erratic likely came from Precambrian bedrock exposures of similar material in the Many Islands Lake area of northeast Saskatchewan. The rodents were mainly consuming the rock for its high calcium content.
