The Everglades are a natural region of tropical wetlands in the southern portion of the U.S. state of Florida, comprising the southern half of a large watershed. The Everglades are shaped by water and fire, experiencing frequent flooding in the wet season and drought in the dry season. Like most regions with this climate type, there are two basic seasons - a "dry season " (winter) which runs from November through April, and a "wet season" (summer) which runs from May through October. The landscapes we see today in Everglades National Park, and in all of south Florida, are the direct result of geologic events of the past and ongoing environmental processes. Although the activities of humans have altered the south Florida landscape, the geologic record is still intact.
The geologic secrets of the earth are visible to all who learn to recognize them. It is impossible to consider the geology of the Everglades without also considering the hydrology.
Primarily consisting of limestone, the bedrock geology of Everglades National Park has responded over time to the ongoing processes of weathering, erosion, compaction of organic sediments, unique hydrologic conditions, and episodes of sea-level rise and fall to produce the landscapes we see today.
The first criterion listed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in its designation of Everglades National Park as a World Heritage Site in 1979 is: The Everglades is a vast, nearly flat seabed that was submerged at the end of the last Ice Age.
Its limestone substrate is one of the most active areas of modern carbonate sedimentation. UNESCO recognized that the subtropical wetlands, coastal and marine...
