Washington's Weirdest Rock

About the Item:  Each of these unique specimens is millions of years old and a wonderful item to give or enjoy yourself.  This may be the weirdest rock in the State of Washington.  For nearly a hundred years, recreational rock collectors as well as professional scientists from around the world have collected and debated the precise nature of these unusual rocks.  Many believe they are prehistoric coprolites (petrified dung).  Not to worry.  The organic matter has been replaced with siderite and limonite, both iron minerals.
