About this map

Río Fajardo winds through the southeastern reaches of this terrain, anchoring a landscape defined by the sharp convergence of municipal boundaries and the steep tropical drainages of the Luquillo Range. Developed based on 1943 topography, the map reveals the agrarian footprint of the mid-1940s, most notably at the Colonia Paraiso settlement near the riverbanks. The intricate network of waterways, including Río Sabana and Río Cristal, illustrates the complex hydrology that dictated early transportation and land use in this part of Puerto Rico.

The northern portion of the sheet is dominated by the community of Sabana, situated where the mountains begin to give way to the coastal plain. Detailed surveying from the U.S. Geological Survey and the Departamento de lo Interior documents the precise division between the Municipio de Rio Grande and Luquillo, as well as the border with the Municipio de Fajardo. This preliminary edition serves as a record of rural development before modern infrastructure altered the flow of the Quebrada Rincon and surrounding valleys.
