About this map

The coastal lowlands and inland foothills of northeast Puerto Rico are defined here by a network of waterways and agricultural barriers during the early 1960s. The Río Grande settlement serves as a central hub, connected to outlying barrios like Hato Caudal and Korea through a transitioning infrastructure of light-duty roads and the Via del Ferrocarril. Along the northern shore, the Atlantic coastline is punctuated by Punta Miquillo and the sheltered Ensenada Comezón, where the Río Espíritu Santo meets the sea.

Inland, the landscape is marked by community landmarks such as the Escuela Luis Calderón and Escuela Juan González, reflecting the local focus on education during this period. The map reveals the intricate drainage of the Ciénaga Baja and the presence of specialized facilities like the Facilidad de Radio and a Pista de Aterrizaje, indicating the area's development beyond its traditional sugar or agricultural roots.
