1942 Map of Moca

About this map

The town of Moca sits at the base of dramatic limestone karst formations, serving as a gateway between the northern coastal plains and the interior mountains of Puerto Rico. This survey, based on work from the 1920s and 30s, reveals a landscape defined by small agricultural settlements and the winding course of the Rio Culebrinas. The infrastructure of the era is remarkably visible, following the American R. R. of Porto Rico as it skirts the northern edge of the hills, connecting stops like Estacion Santiago and Estacion Montana. Local industry and public works are anchored by the Planta Electrica de Isabela and the Planta de Filtracion, while rural life is centered around local institutions such as the Escuela Segunda Unidad de Voladoras and the Iglesia de la Virgen del Rosario. The map captures the complex topography of the Jaicoa and Centro Cordillera ranges, dotted with named peaks like Monte Mariquita and Cerro La Silla.
