1940 John Steinbeck and Ed Ricketts visited Puerto Escondido, inspiring Steinbeck’s classic novel, The Log From the Sea of Cortez. Steinbeck wrote: "After noon we arrived at Puerto Escondido, the Hidden Harbor, a place of magic. If one wished to design a secret personal bay, one would probably build something like this little harbor...we went on a sheep hunt with Leopoldo Perpuly in the mountains in the back of the port...where a tiny stream of water fell hundreds of feet from pool to pool. There were palm trees and wild grapes and ferns, and the water was cool and sweet."
1976 The Mexican Federal government agency, Fonatur (National Fund for the Promotion of Tourism) began to implement a 3 Step Development Plan approved by Semarnat in Loreto:
1977-1982 Fonatur dredged the Marina Puerto Escondido entrance channel, increasing the width and depth to support a marina; dredged and created two of the three planned artificial islands in the bay; constructed an ellipse with seawall and jetty; installed well; water treatment plant and roads; built marina, launching ramp and dry storage.
1987 Jacques Cousteau and Jean Cousteau explored the Sea of Cortez, which he then coined "The Aquarium of the World." Jacques Cousteau’s tireless efforts fighting to protect the Sea of Cortez led to one of the islands at the southern end of the gulf being named Isla Jacques Cousteau in his honor.
