At the point where the Saint Johns River emerges from nearby Lake Harney stands a shell mound complex important to the history and prehistory of Seminole County. Examined by anthropologists Daniel Britton in the 1850s, Jeffries Wyman in the 1860s, and Clarence B. Moore in the 1890s, it remains a significant archaeological and anthropological site. Archaeological evidence shows its use by the prehistoric Orange culture from 2000-500 BC and the Saint Johns culture from 500 BC-1500 AD, and later by the historic Seminole. By the time of American settlement of the area, King Philip, also called Emaltha, and his son Wildcat, also called Coacoochee, with about 200 Seminoles had established a settlement here known as King Philipstown. At the start of the Second Seminole Indian War, the Indians, feeling threatened by the army camp established at Lake Monroe in 1836-37, attacked the camp on February 8, 1837. They were repulsed, and by the early 1840s the army had driven them from the area. About 1850, a man named Cook operated a ferry here, and the place became known as Cook's Ferry. After the Florida East Coast Railroad crossed the river in 1911, the area became known as Bridge End. From 1916-1940, the self-sufficient cypress mill town of 200 people known as Osceola flourished here under the Osceola Cypress Co., with daily lumber cutting of about 60,000 board feet. In 1926 it was called the principal commercial industrial community of Seminole County. After the timber was gone, the remaining visible relics were timber pilings along the riverbank and, on land, the square concrete block former company vault. The area is now known as Osceola Fish Camp.
