Río Culebrinas winds through this interior landscape of western Puerto Rico, defining a region characterized by intricate topography and dispersed rural settlements. This 1950 edition, produced by the U.S. Geological Survey in cooperation with the Gobierno de Puerto Rico, reveals the dense network of hillside farms and trails across the barrios of Cerro Gordo, Mariani, and Naranjo. The terrain is deeply incised by numerous waterways, including Quebrada Grande, Quebrada Casimba, and Quebrada Palmarinas, which shape the agricultural life of the district. The mapping reflects a period when the inland economy relied heavily on local hydrology and a complex web of footpaths and secondary roads connecting mountain communities like Humatas and Voladoras. This survey provides a precise record of rural life and land use just before more modern infrastructure began to alter these highland corridors.
