Puerto Rico is the eastern most island of the Greater

Antilles and is located in the northwest section of the

Caribbean Sea. Puerto Rico is about 160 kilometers south of

the Puerto Rico Trench which has a depth of 8.36 kilometers

making it the deepest part of the Atlantic Ocean.

Puerto Rico (Fig. 1.A) can be divided into three main

geographic divisions:

1. Mountain Core

2. Karst Topography Belt
3. Flat Coastal Plain

The mountainous core consists predominantly of the

lower Cretaceous to middle Eocene volcanic formations. Most

of the lower Cretaceous rocks are submarine, deep-water,

volcanic-ash deposits interspursed with pillow lavas. In

the south-central and northwest parts of the island, the

central core extends to the Caribbean Coast and includes

rock of middle Tertiary age. These younger rocks consist

of conglomerates, sands, clays, chalks, and limestones which

combine to form the Juana Diaz formation and Ponce

limestone.

The karst topography belt occupies the north-central

and northwest part of Puerto Rico. The relief in this area

varies from extremely rugged terrain to rather gently

rolling hills. Most of the drainage in this region is
underground with the exception of several rivers that flow

across the belt from the central mountainous area to the

Atlantic Ocean. Portions of these rivers also flow under-
