Dan Rodricks: A beautifully restored river more Marylanders need to see | COMMENTARY

I call it the “rock of ages” because, when I first came upon it during a float trip on the North Branch of the Potomac River 30 years ago, it resounded silently with the mighty power of time. The massive rock, millions of years old, rose 70 feet above us, just downstream of a bend in the river and upstream of a place called Black Oak, in Western Maryland’s Allegany County.
