The Observatorio de Arecibo stands as a prominent landmark in the northeastern portion of this karst landscape, where the terrain is defined by dramatic subterranean drainage and surface depressions. The Tres Pueblos Sinkhole highlights this unique geomorphology near the settlement of Bayaney, illustrating the complex limestone environment of the Island of Puerto Rico. A network of watercourses including the Río Camuy, Río Tanamá, and Río Ángeles dissect the region, while the town of Lares anchors the southwestern quadrant. The map detail traces several municipal boundaries and smaller communities like Quebrada Anón and Quebrada Pasto, which are connected by a web of local routes such as PR-129 and PR-111. Elevated features like Cerro Palma and Hoya Caña provide significant relief across this transition between the northern coastal plains and the central interior mountains.
