This area was entirely covered by ocean. As the ocean shoreline advanced inland, waves slowly wore away hills and other land formations in their path. As time passed, billions of seashells and other remains of ocean life sank to the sea floor. Tightly packed, they eventually became beds of a soft rock called limestone. Over time, rivers and streams deposited into the ocean large amounts of soil, clay, and rock that had erodedfrom the hills and mountains to the north. As a result, thousands of feet
of sediment —or settled deposits— covered the ocean floor.
called tidal rivers—spill over their banks and flood low-lying areas, thus creating saltwater marshes. These marshes are one of the most important features of the coast.
