…Fones Cliffs sits on the north side of the #Rappahannock River & is geologically unique because of its distinctive white diatomaceous earth—formed from fossilized remains of aquatic organisms from 5 million years ago when a shallow sea covered much of the area, acc/to Julia King, chair of the anthropology department at St. Mary’s College. #Wildlife experts said it’s a rare spot because its #wetlands are largely untouched & serve as an ideal habitat for bald eagles, fish & other animals.
