About this map

San Sebastián serves as the primary hub in this detailed look at Puerto Rico's interior during the early 21st century. The landscape is defined by an intricate network of waterways, including the winding Rio Culebrinas and the Rio Guatemala, which carve through the terrain toward the northern reaches of the island. Significant agricultural and industrial heritage is evident at Central Soller, while the town of Lares anchors the eastern edge of the survey.

Water management and natural drainage dominate the geography, from the northern Lago de Guajataca to the southern Rio Grande de Añasco. Dozens of smaller streams, such as Quebrada Lajas, Quebrada Infierno, and Quebrada Salada, illustrate the complex hydrology that supported local settlements like Las Marías. The layout of transportation routes, including Avenida Emerito Estrada Rivera, shows how modern infrastructure follows the ancient contours of these river valleys.
