For millennia, gray whales have made an annual pilgrimage from the cold, rich marine waters in the Gulf of Alaska to the warm, protected waters of San Ignacio Lagoon. The calm bay sits on the west coast of Baja California. There the mother whales feel safe from predators and givebirth to their calves. They also urge the newborn giants to make contact with humans, who await them in boats, hoping for an opportunity to pet them. In this vast shelter, both the Mexican government and the boatmen, fishermen the rest of the year, guard the whales and nurture the friendship between people and the gentle leviathans.
