River Blackwater Puzzle

    When I was a geography student in college 20 years ago, our Geomorphology lecturer pointed out to us that the course of the River Blackwater was an enduring puzzle.

    For most of its length, it runs from west to east, but then at Cappoquin in Waterford it turns abruptly south to enter the sea at Youghal. Our lecturer said that this didn't make geologic sense as the river had to cut through harder sandstone rock units in its southwards course.

    I'm intrigued by this puzzle. In the past two decades, has it been solved? Or does it remain a mystery?
