About this map

The hills of Bosque Insular de Maricao dominate the landscape of western Puerto Rico in the late 1930s, showing a region defined by its steep terrain and agricultural estates. Numerous haciendas, including Hacienda Monita, Hacienda Esperanza, and Hacienda Corcega, are scattered across the mountainous ridges, connected by a network of trails and roads such as Carretera No. 16. The agricultural character of the era is evidenced by these family-named landholdings and the presence of several small chapels and churches like Iglesia de San Jose and the Capilla de la Milagrosa.

Transport and public infrastructure are anchored by the American R. R. running through the southern valley alongside the Rio Porto Rico. Institutional landmarks like the Hospital de Tuberculosis sit near the western edge, while the village of Rosario serves as a local hub. The map provides a detailed view of the complex hydrography, with the Rio Rosario and many quebradas like Quebrada Canas carving through the highlands near peaks such as Pico San Bernardo.
