The formation of Everglades National Park is the result of complex geological and hydrological processes that have shaped South Florida over millions of years. Its distinctive wetlands developed through the interaction of limestone geology, changing sea levels, freshwater flow, and the accumulation of organic material.

Limestone Foundation: The Everglades rests on a broad, shallow limestone platform that formed from sediments and the remains of marine organisms deposited in ancient seas. This porous limestone provides the foundation for the region's wetlands and strongly influences how water moves through the landscape.

Sea Level Changes: Repeated changes in sea level during glacial and interglacial periods exposed and submerged portions of the Florida Platform. These fluctuations helped shape the low-lying landscape and influenced the development of freshwater wetlands and coastal environments.

Peat Formation: As freshwater plants grew and died in the wetlands, their organic remains accumulated faster than they could completely decompose. Over thousands of years, this material formed layers of peat that helped create the characteristic shallow wetlands of the Everglades.

River of Grass: The Everglades is often described as a "River of Grass" because freshwater moves slowly southward across the broad, nearly level landscape as a shallow sheet of water. Sawgrass and other wetland plants thrive in this environment, creating the ecosystem's distinctive appearance.

Hydrological Processes: Seasonal rainfall is the primary source of water for the Everglades. Water flows south from the greater Everglades watershed through wetlands, marshes, sloughs, and mangrove ecosystems before eventually reaching Florida Bay and the Gulf of Mexico.

Coastal and Marine Influences: At the southern end of the Everglades, freshwater wetlands transition into mangrove forests, estuaries, and shallow coastal waters. The interaction between freshwater and saltwater has helped create one of the most diverse wetland and coastal ecosystems in North America.

Human Alteration: Beginning in the late 19th and especially the 20th century, drainage canals, levees, flood-control structures, and water diversions substantially altered the natural flow of water through the Everglades. These changes contributed to habitat loss, altered salinity patterns, and other ecological problems that modern restoration efforts seek to address.

Overall, the geological and hydrological history of Everglades National Park reflects the long-term interaction of limestone geology, sea-level fluctuations, freshwater flow, vegetation, and coastal processes. These forces created the unique wetland landscape that makes the Everglades one of the world's most distinctive ecosystems.

The Everglades has a rich Native American history, with Indigenous peoples maintaining deep cultural, spiritual, and economic connections to the region for thousands of years. The Miccosukee and Seminole peoples are particularly closely associated with the Everglades and continue to maintain strong ties to the landscape today.

Miccosukee Tribe: The Miccosukee people have longstanding cultural and historical connections to the Everglades. They traditionally lived in elevated chickees, which were well suited to the region's wet environment, and relied on hunting, fishing, gathering, and other natural resources for their livelihoods. Materials such as palmetto, cypress, and other native plants were used to make tools, shelters, clothing, and crafts.

Seminole Tribe: The Seminole people developed strong connections to the Everglades, particularly during the 19th century as they sought refuge from U.S. military campaigns and forced removal. They adapted their traditional practices to the wetland environment and relied on hunting, fishing, farming, and gathering. Today, the Seminole Tribe of Florida continues to preserve its cultural traditions and history.

Traditional Land Use: Indigenous communities developed extensive knowledge of the Everglades' seasonal cycles, waterways, plants, and wildlife. Dugout canoes provided an important means of transportation through the wetlands, while hunting, fishing, and gathering allowed communities to make use of the region's diverse resources.

Chickee Architecture: Chickees, traditionally built on raised platforms with open sides and thatched roofs, were well adapted to the hot, wet conditions of the Everglades. This distinctive architectural tradition remains an important symbol of Seminole and Miccosukee culture.

Cultural Significance: The Everglades holds profound cultural and spiritual importance for Indigenous communities. Traditional knowledge emphasizes relationships among people, wildlife, water, plants, and the broader landscape, reflecting a longstanding understanding of the interconnectedness of the ecosystem.

European and American Expansion: European colonization and later U.S. expansion brought warfare, disease, displacement, and changes in land use that profoundly affected Indigenous communities. Despite these pressures, Seminole and Miccosukee people maintained their presence and cultural traditions in South Florida.

Contemporary Presence: The Miccosukee Tribe and Seminole Tribe of Florida continue to maintain strong cultural connections to the Everglades. Their traditional knowledge, cultural practices, and perspectives contribute to contemporary efforts to understand and protect the region's natural and cultural heritage.

The Native American history of the Everglades demonstrates that the region is not simply a wilderness landscape but also a cultural homeland shaped by generations of Indigenous knowledge, traditions, and relationships with the environment.
