A well-known episode in the Second Seminole War occurred in or near Shark Valley. In the late 1830s, groups of Spanish Indians successively raided a guarded trading post on the Caloosahatchee River in 1839 and committed a massacre on Indian Key in 1840.[5] The Spanish Indians, who resided in Southwest Florida, were a mix of Creek refugees and people of mixed Native American and Spanish, possibly even Calusa, descent.[6] On December 4, 1840, responding to attacks by the Spanish Indians, 90 men under the command of Lieutenant ColonelW. S. Harney targeted one of their key leaders, Chakaika (sometimes spelled Chekika).[7] The men departed from Fort Dallas at the mouth of the Miami River, now Downtown Miami, and reached Chakaika's hideout in the Everglades. They found Chakaika with some of his rebels, shot him, and had him hanged on "Chakaika's island," a tree island in the Everglades.[7] This tree island is believed to be present-day Chekika Island, located at the beginning of Shark Valley.[1]
The observation tower at Shark Valley was designed by the prominent South Florida architect Edward M. Ghezzi. It was built in 1964 as part of the Mission 66 projects throughout the national parks. The tower design is similar to that of the tower on Kuwohi in Smoky Mountain National Park[8]
