1947 Map of El Yunque SO
USGS Topo · Published 1947About this map
The Sierra de Luquillo range dominates this 1940s topographic study, illustrating the complex watershed of eastern Puerto Rico within the Caribbean National Forest. The map detail follows the steep descent of several major river systems, including the headwaters of the Río Grande de Loíza and the Río Espíritu Santo. Significant high points like El Toro Southwest Peak and El Cacique define the ridgelines that separate the municipal boundaries of Municipio de Rio Grande, Municipio de Naguabo, and Municipio de Juncos. This preliminary survey focuses heavily on the natural hydrology and elevation of the forest reserve before extensive modern development, tracing the paths of the Río Gurabo and Río Cubuy as they flow from the peaks toward the surrounding coastal valleys.
