1947 Map of Comerio NE

About this map

Cerro Santa Bárbara and Cerro La Tiza dominate this 1943 topographic study, revealing the interior highlands of Puerto Rico before modern development reshaped the landscape. The intricate drainage network of the Río La Plata basin is shown in detail, including tributaries like Quebrada Ceiba, Quebrada Pueblo, and Quebrada Prieta. This preliminary edition, issued by the United States Department of the Interior, serves as a dense record of early rural settlement patterns. A complex web of small dwellings and trails connects the steep ridges, illustrating a mountain economy reliant on foot and animal transport. The map also delineates crucial municipal boundaries where Comerio, Aguas Buenas, Naranjito, and Bayamon meet, providing essential data for regional genealogy and land history research.
