Rock erosion

Visitors pause to take in the view at Haystack Rock last Friday.

CANNON BEACH — A boy picked up a chunk of stone and started methodically smashing barnacles in the protected marine garden at Haystack Rock.

As he hit the small creatures and pummeled the rocks they lived on last Friday before he was told to leave the garden, he was unwittingly mimicking the natural forces that are slowly reshaping and could eventually erase the massive landmark behind him.
