On April 12, 1528, the expedition spotted land north of what is now Tampa Bay. They turned south and traveled for two days looking for what the pilot Miruelo described as a great harbor. During these two days, one of the five remaining ships was lost. Finally, after spotting a shallow bay, Narváez ordered entry. They passed into Boca Ciega Bay north of the entrance to Tampa Bay. They spotted buildings set upon earthen mounds, encouraging signs of culture (and wealth), food, and water. The natives have since been identified as members of the Safety Harbor Culture. The Spaniards dropped anchors and prepared to go ashore. Narváez landed with 300 men in Boca Ciega Bay at what is known as the Jungle Prada Site in present-day St. Petersburg.
