|Historic map of the three major|
watersheds of the Big Cypress Basin,
as defined by Klein (1970).
It wasn't until Jack Meeder clued me in to its tie in to (as Jack calls it) "Immokalee Mountain" (i.e. max elevation 42 ft above sea level) and the Caloosahatchee's Fort Thomson Falls (no longer in existence), that the pivotal role the Big Cypress Swamp played in the pre-drainage Everglades finally snapped into place.
|Ft Thompson Falls were located|
about 2 miles east of LaBelle and formed
the headwater source of the Caloosahatchee
River, with a 4-10 ft drop.
