Pacific Coast: Cabo Corrientes-Togoromá

The Cabo Corrientes-Togoromá coastline is approximately 100 km long and has a general north-south orientation (Fig. 3). This depositional fringe varies in width from 1 km at the mouth of the Baudó River to 9 km at the Docampadó River. Coastal morphology is characterized by a chain of barrier islands, backed by estuarine lagoons, mangrove swamps, and a narrow belt of freshwater swamps. The barrier islands of this coast (Fig. 13), some of them regressive, are no more than 2 m high, 3.2 to 15.8 km long, and have areas between 0.6 and 25.2 km2 (Martínez et al. 1995).

Holocene deposits between Cabo Corrientes and Togoromá are limited to the east by paleo-cliffs (Fig. 14) cut into Tertiary sedimentary rocks. The paleo-cliffs mark the maximum advance of the Flandrian transgression in the area. The coastal relief, which suggests tectonic uplift, shows well-defined structural controls according to vertical fracturing N60ºE and N30ºW, and a highly dissected terrace, which is 80 m above present sea level (Correa 1996, Robertson 1997).

Islas Catripe and Baudó-Piliza barrier islands, approximately 12 km in length, are the two longest barrier islands of the Pacific Coast.
