About this map

The southeastern coastline of Puerto Rico is dominated by the Sierra de Guardarrayas and the prominent headland of Pta Tuna. This mid-century survey reveals a coastal landscape defined by the agricultural footprint of Hacienda San Isidro and the maritime importance of the Faro lighthouse standing sentinel over the Mar de Antillas. The inland areas show the Municipio de Maunabo boundary, where numerous streams like Quebrada Arenas and Quebrada Florida descend from the ridges toward the sea.

Local infrastructure in the 1940s is anchored by the Escuela Segunda Unidad de Guardarraya and the small settlement at Puerto Maunabo. The terrain is characterized by steep rises, such as Cerro Piedra Hueca, and dramatic coastal features like Cabo Mala Pascua, which marks a sharp transition in the shoreline. This map provides a detailed view of the regional drainage patterns and early road networks connecting coastal holdings to the mountainous interior.
