Sailboat used to travel to Isla Caja de Muertos to complete topographic mapping. Puerto Rico. 1942.

Album caption: This sailboat was used to travel to Isla Caja de Muertos to complete topographic mapping of the small island southeast of Ponce. The high mountains in the background are in the Cordillera Central. The highest point in Puerto Rico is Cerro de Punta, 4389 feet above sea level, and which can be seen in this photograph. Columbus followed the south coast of the island and in these waters on his second voyage in 1493. (Photos 24 and 25 were taken by me in December 1942 with a Rolleiflex camera.) No index card.
