About this map

The Río Grande de Loíza winds through a landscape of traditional agricultural barrios in the mid-1940s, marking the boundaries between Trujillo Alto and Carolina. This period captures the rural educational infrastructure of the era, visible in the distributed locations of the Escuela Segunda Unidad de Cacao and Escuela Segunda Unidad de Carruzos. These "second unit" schools were central to the rural community, often focusing on vocational and agricultural training for local families.

Industrial activity is concentrated near the southern edge along the Río Gurabo, where the Sugar Associates facility and an adjacent Military Reservation indicate the economic and strategic importance of the river valley. Numerous watercourses, such as the Quebrada Infierno and Río Canovanillas, descend from high points like La Silla, feeding the valley floors where small settlements like Campo Rico and Trujillo Bajo are situated. The map provides a detailed view of the complex barrio boundaries and the winding network of secondary roads that connected these interior mountain communities before modern highway expansion.
