Zeisberger wrote Fachsdjcck in the Minsi dialect. The valley gave name to the stream. In Rockland County it has been corrupted to Paskack, Pasqueck, etc.

Paquapick is entered on Pownal's map as the name of Passaic Falls. It is from Poqiii, "Divided, broken," and -apuchk, "Rock."

It is this rock and chasm to which the name refers -- "Divided rock," or an open place in a rock.
