About this map

The interior highlands of western Puerto Rico meet the coastal edge of Mayagüez and Hormigueros in this 2018 survey. The landscape is defined by its complex hydrology and dramatic relief, where the Montañas de Uroyan and Pico San Bernardo rise above a dense network of watercourses. Significant water management features are evident, including the Represa de Mayagüez on the Rio Yagüez and the Represa de San Germán further south.

Settlement patterns follow the winding ridgelines and valley floors, with distinct communities like Los Penones situated among the folds of the Cuchilla Los Matos. The map documents the intricate municipal boundaries that converge in these mountains, including the borders of Añasco, San Germán, and Maricao. These summits, such as Cerro Leclerc and the Cerro de la Candelaria, serve as natural dividers for the numerous quebradas that feed into larger rivers like the Rio Rosario.
