Ruins were visited at Isla del Sol and Isla de la Luna, Then dives were made in the area visiting minor underwater ruins. The expected rich schools of fish are not found. For the next four weeks dives were made in the area. During these dives many dead fish were found and collected. Large toads were found and noted.[33] Samples of the dead fish and the toads were sent to The Oceanographic Museum (Musée océanographique) in Monaco for study. To help map the bottom of the lake Dr Harold Edgerton arrived from MIT with depth mapping, equipment.[34] [35] After mapping the lake a area is selected for the subs to dive in. Floats are added to the subs. The two mini subs were launched with Jacques Cousteau and Albert Falco[36] at the controls. Dives dived with the subs to a depth of 100 feet. The subs continued down to a depth of 400 feet. The toads were found at 400 feet below water. After the sub dive the results for the test on the dead fish arrived from Monico. When trout were introduced into the lake in 1940 parasites were introduced with them.[37
