Upper Matecumbe Key
Upper Matecumbe Key is an island in the upper Florida Keys.
U.S. 1 crosses the key at approximately mile markers 79–83.5, between Windley Key and Lower Matecumbe Key.
All of the key is within the Village of Islamorada as of November 4, 1997, when it was incorporated.
The island lies to the southwest of Windley Key, and to the northeast of Lower Matecumbe Key.
The history of the names of both this key and Lower Matecumbe Key are very confusing, as identical names have been used at different times to designate both keys. Upper Matecumbe Key is the location of the original settlement site of Islamorada. There are a number of Indian mounds and habitation sites located here.
