About this map

The Caribbean National Forest dominates the landscape of this northeastern Puerto Rican interior, centered on the heights of the Cuchilla de Luiquillo. Elevations climb toward the iconic Pico El Yunque and Los Picachos, where mountain streams like the Río Espíritu Santo and Río Mameyes begin their descent. This 1960s-era data, updated in the early 1980s, reveals a network of rural education and youth camps, including Escuela Segunda Unidad Cabana Cepeda and Campamento Eliza Colberg.

Lower elevations in the north and west show the transition from agricultural zones like Cienaga Baja to the small village of Mameyes (Palmer PO). The map tracks the headwaters of numerous rivers, such as the Río Icacos and Río Blanco, showing the complex drainage of the Sierra Luquillo before modern infrastructure significantly altered the lower watersheds. Local family names and rural schools like Escuela Guzmán Arriba provide essential points of reference for genealogical research in these mountain barrios.
