About this map

Coastal sugar cultivation and early municipal development define this northeast Puerto Rico corridor in the late 1940s. The landscape is dominated by the industrial agricultural footprint of the colonias, including Colonia Mimi, Colonia Dolores, and Colonia Blasina, which were essential to the local economy. An intricate network of irrigation and drainage canals, such as Canal Gordiani and Canal Concella, crisscrosses the low-lying Ciénaga Baja near the mouth of the Río Herrera.
