'^This vast expanse extends from Tiburon Island across the Canal de Infiemillo (Channel of little Hell) that separates from the mainland, and on northward up the coastline. Astronomical terms would be necessary to describe the abundance and numbers of living creatures that inhabit these waters"^ 'R. S. Felger and M. B. Moser. 1985. People of the Desert and Sea.
