Calusa and their ancestors
Marco Island has about 6,000 years of human habitation. The rare wooden and fiber artifacts found at Key Marco are most often attributed to the late precontact Calusa (1300-1513 CE) or the earlier Glades culture, and the Calusa dominated Florida's southwest coast for centuries.
