1947 Map of Cayey NO

About this map

The Cordillera Central dominates this 1943 topographic survey, illustrating the complex ridgelines and deep valleys where the municipal boundaries of Aibonito, Cayey, Coamo, and Salinas converge. The landscape is defined by significant elevations such as Cerro Planada, Peña Dominga, and Cerro Avispa, which rise above the headwaters of the Rio Lapa and Rio Cuyon. Settlement patterns in this era are concentrated in areas like Las Tetas and Proyecto Vazquez, with the map detailing the winding road networks and small structures that supported local agricultural life before mid-century modernization. The meticulous contouring reveals the steep descent from high peaks like La Piedra toward the southern coastal plains, providing a clear view of the drainage systems including the Maton and various unnamed quebradas that shaped the region's hydrology and land use during the 1940s.
