1947 Map of El Yunque NO

About this map

Caribbean National Forest dominates the Southern landscape of this mid-century topographic survey, where the steep, densely contoured ridges of the Luquillo Mountains begin their descent toward the coast. Published by the Department of the Interior under Comisionado Orlando R. Mendez, this preliminary map captures the rural character of the region during the late 1940s. The dense network of small dwellings and footpaths clustered near Escuela Casiano Cepeda reflects the traditional settlement patterns of the Municipio de Rio Grande before modern infrastructure arrived. Hydrological detail is prominent, tracing the headwaters and winding paths of the Rio Espiritu Santo and Rio Herrera as they cut through the tropical terrain. The map also delineates the administrative boundary with the Municipio de Loiza, providing a precise look at local land divisions and the placement of the Quebrada El Verde.
