1946 Map of Comerio

About this map

Río La Plata carves a winding path through this mid-1940s landscape, connecting the urban center of Comerío with the highland basin surrounding Cidra. The survey, published by the Government of Puerto Rico and the U.S. Geological Survey, illustrates a transition in rural education and social infrastructure. Multiple educational sites, including the Escuela Superior de Comerío and several rural second units like Escuela Segunda Unidad de Toíta, are distributed along the ridges and valleys. The presence of the Proyecto La Plata and the Centro Comunal Nogueras suggests the era's focus on rural development and community organization. Across the southern portion of the sheet, the influence of the sugar industry is marked by the presence of Central Cayey. The map reveals a densely named network of tributaries, such as Quebrada Doña Elena and Quebrada Usabón, which defined the boundaries of numerous municipios.
