GEOGRAPHICAL SETTING As this report is concerned with the archaeological resources of the island of St. John in the United States Virgin Islands, it is well that we should initially place this group geographically and geologically in the general West Indian area. The West Indies or Antilles constitute as a whole the northern and eastern limits of the Caribbean Sea from the Yucatan Channel to Venezuela in South America. Generally the island chain is divided into two major divisions, the Greater and Lesser Antilles. The Greater Antilles are represented by such major island groups as Cuba, Jamaica, Hispaniola (Haiti and Dominican Republic), and Puerto Rico. As is pointed out below, geologists include the Virgin Islands in the Greater Antilles. On the other hand, all of the island arc from the Virgin Islands southward through Grenada and Trini- dad is recognized as the Lesser Antilles. Some would define Trini- dad as a detached land mass of Venezuela and therefore not a true portion of the Lesser Antilles. Those familiar with sailing in the Lesser Antilles will recognize a further division of the arc into the Windward and Leeward groups. The Windwards are identified as those islands from Grenada to and including Martin- ique, while the grouping northward through the Virgin Islands delineates the Leeward Islands.
