     In 1988 a map was prepared for Cayo Santiago Island to provide a locational reference for scientific projects, and for use by the Caribbean Primate Research Center to orient new scientists to the island. When the map was created, prints of aerial photographs from the Puerto Rico Department of Transportation and field measurements were the only geographic information available. The 1988 map has been used for many research activities and incorporated into publications and theses. Although other storms since 1988 had affected Cayo Santiago, none have had the physical impact of Maria; rendering the existing map no longer valid. Using the old map, we measured the island and ground verified the physical changes. High quality digital satellite imagery was made available through NOAA and USGS. These images, taken prior to and shortly after the hurricane, facilitated improved plotting of all aspects of the island. Prior to Hurricane Maria, Cayo Santiago was an island that included two rocky outcrops of approximately 30 meters in elevation connected by a lowland area that makes up approximately half the total area of the island. The hurricane flooded the lower areas of the island and breached one location, effectively creating two islands. Using the same format and map scale, a new map of the island has been produced that reflects these changes.
