Did You Know?

A mussel or clam on the sand.  It is dark and bumpy.

Winged maple leaf mussels were thought to be extinct until some were rediscovered in the St. Croix River in 1987. Today scientists are helping to raise young mussels and re-introducing them into their former range including St. Croix National Scenic Riverway to help prevent future extinction.
