1947 Map of Juncos SO

About this map

Río Grande and its tributary, Río Cayaguas, carve through the complex interior terrain of San Lorenzo during the mid-1940s. This preliminary topographical study highlights a landscape dominated by drainage networks and scattered rural homesteads, reflecting the agricultural and residential patterns of the period. A significant institutional landmark is the Escuela Segunda Unidad de Quebrada Honda, located near the southern reaches of Quebrada Honda. The naming of numerous smaller streams, such as Quebrada Salvatierra and Quebrada Prieta, indicates the vital importance of water resources to the local community before modern infrastructure became widespread. To the east, the prominent Piedra Blanca provides a natural reference point amidst the dense contour lines of the central hills. The map captures a moment of transition for the region, documented under the authority of the Departamento de lo Interior and Commissioner Jorge J. Jiménez.
