December 6, 2003 The Florida Keys are a chain of islands,
islets, and reefs extending from Virginia Key to the Dry
Tortugas for about 309 kilometers. Stretched out into the waters
of the Strait of Florida between the Gulf of Mexico to the west
and the Atlantic Ocean to the east, the keys are chiefly
limestone and coral formations. In this image from the Advanced
Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on
the Terra satellite, the keys form a mosaic of green and white
against the blues of the sea. The white areas clearly show where
the islands have been developed with both communities and roads.
Among the roads is the causeway that connects the Keys to the
mainland and to one another. Topics: Environment, Monroe County,
