2013 Map of Rosario

About this map

Rosario and the eastern outskirts of Hormigueros anchor this rugged landscape in western Puerto Rico, where the interior mountains give way to a dense network of watercourses. The terrain is defined by the Montanas de Uroyan and prominent heights such as Cerro de la Candelaria and Pico San Bernardo. This 2013 survey illustrates the complex intersection of municipal boundaries, including Mayagüez, San Germán, and Maricao, which follow the winding ridges and riverbeds. The local water infrastructure is prominent, featuring the Represa de Mayaguez and Represa de San German. A intricate web of streams like Rio Rosario, Rio Duey, and Quebrada del Oro carve through the foothills, indicating a landscape heavily influenced by tropical drainage patterns and steep elevation changes across the Island of Puerto Rico.
