The interior highlands of Guayanilla and Yauco are defined here by steep ridges and a complex network of waterways, surveyed just as Puerto Rico’s agricultural landscape was undergoing post-war transition. Agricultural history is anchored by the presence of Hacienda Mogote and Hacienda Catalina, reflecting the importance of coffee and sugar production in these mountain corridors. The Río Guayanilla and Río Macaná drain the rugged terrain, while the northeastern corner of the map touches the protected Bosque Insular de Guilarte. In the southern portion of the survey, the Escuela Segunda Unidad de Santo Domingo stands as a focal point for the local community, situated where the valley begins to widen.
