About this map

Hacienda life and coffee-era agriculture dominate this landscape during the late 1930s and 1940s, situated at the junction of several municipal boundaries including Mayaguez, Añasco, and San Germán. The settlement of Rosario serves as a central hub, surrounded by a dense network of family-owned estates such as Hacienda Juanita, Hacienda Esperanza, and Hacienda Corcega. These haciendas, often centered around mountain streams like the Rio Rosario and Rio Cañas, reflect the agrarian economy before modern industrialization shifted the island's demographics.

Institutional and religious landmarks are scattered through the hills, including the Hospital de Tuberculosos and several rural chapels like Capilla de la Milagrosa and Iglesia Santa Teresita. The presence of the Presidio de Mayaguez and the Transmision line indicates the growing infrastructure connecting these mountain barrios. Steep topography is noted by named peaks like Cerro de la Candelaria and Pico San Bernardo, which define the drainage basins of the Rio Duey and Rio Hoconuco.
