I had to do some field work this summer to find out whether I should classify the section 

 of the coast between the Mississippi and Apalachicola deltas as deltaic [1.2], but I believe I 

 should. 



There is a 200-mile delta [1.11] on the Isthmus of Tehuantepac in the rain forest area. 



The two limestone peninsulas [2] of Florida and Yucatan are shown, and imposed on their 

 shelves is what has been called a biogenous type of coast. I do not consider this a basic coastal 

 type as far as the land is concerned, but it is a marine overlay on other basic geological units 

 such as the drowned limestone peninsulas. We could consider the limestone itself as a product
