present-day southern Alabama to trade, so the peoples were part of a broader regional and even continental network of relations. The best-known Pensacola culture site in terms of archeology is the Bottle Creek site, a large site located west of Pensacola north of Mobile, Alabama. This site has at least 18 large earthwork mounds, five of which are arranged around a central plaza. Its main occupation was from 1250 CE to 1550. It was a ceremonial center for the Pensacola people and a gateway to their society. This site would have had easy access by a dugout canoe, the main mode of transportation used by the Pensacola. Spanish The area's written recorded history begins in the 16th century, with documentation by Spanish explorers who were the first Europeans to reach the area. The expeditions of Pánfilo de Narváez in 1528 and Hernando de Soto in 1539 both visited Pensacola Bay, the latter of which documented the name "Bay of Ochuse". In the age of sailing ships Pensacola was the busiest port on the Gulf of Mexico, having the deepest harbor on the Gulf. In 1559, Tristán de Luna y Arellano landed with some 1,500 people on 11 ships from Veracruz, Mexico. The expedition was to establish an outpost, ultimately called Santa María de Ochuse by Luna, as a base for Spanish efforts to colonize Santa Elena (present-day Parris Island, South Carolina.) But the colony was decimated by a hurricane on September 19, 1559, which killed an unknown number of sailors and colonists, sank six ships, grounded a seventh, and ruined supplies. The survivors struggled to survive, most moving inland to what is now central Alabama for several months in 1560 before returning to the coast; but in 1561, the effort was abandoned. Some of the survivors eventually sailed to Santa Elena, but another storm struck there. Survivors made their way to Cuba and finally returned to Pensacola, where the remaining fifty at Pensacola were taken back to Veracruz. The Viceroy's advisers later concluded that northwest Florida was too dangerous to settle. They ignored it for 137 years. In the late 17th century, the French began exploring the lower Mississippi River with the intention of colonizing the region as part of La Louisiane or New France in North America. Fearful that Spanish territory would be threatened, the Spanish founded a new settlement in western Florida. In 1698 they established a fortified
