Geological Feature/Landform

Ometepe Island is located in southwest Nicaragua, formed by two volcanoes rising out of Lake Nicargua. It is the lake's largest island. The two imposing volcanoes, Maderas and Concepcion, define its topography. The island was designated a Biosphere Reserve in 2010.

Beginning high in the Sierra Parima Mountains of Venezuela and Brazil, the Orinoco River flows in a giant arc before discharging in the Atlantic Ocean in Venezuela. Its tributaries are the major transportation system for eastern and interior Venezuela and the llanos of Colombia.

The Paraná River is the second longest river in South America. Running through Brazil, Paraguay and Argentina, it becomes an alluvial basin before emptying into the Río de la Plata. The Paraná Delta consists of several islands known as the Islas del Paraná.

The Peru–Chile Trench, also known as the Atacama Trench, is an oceanic trench in the eastern Pacific Ocean off the coast of Peru and Chile. It delineates the boundary between the subducting Nazca Plate and the overriding South American Plate.

The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean, roughly parallel to the northern coast of Puerto Rico. The deepest point in the Atlantic Ocean, the Milwaukee Depth, lies at a depth of 27,493 ft in the western end of the trench.

Rincón de la Vieja Volcano National Park spans over 34,000 acres and helps protect both montane forests and dwarf cloud forests. Rincón de la Vieja Volcano, an active andesitic complex volcano, is set within the park and is one of six active Costa Rican volcanoes.

Río de la Plata is a tapering intrusion of the Atlantic Ocean on the east coast of South America between Uruguay to the north and Argentina to the south. It empties into the Atlantic Ocean. The Rio de La Plata drainage basin is bounded by the Brazilian Highlands, the Andes Mountains and Patagonia.

The Sierra de las Minas mountain range runs from east to west through Guatemala's southeast highlands. The Sierra de las Minas Biosphere Reserve contains a substantial part of the range as well as an estimated 60 percent of Guatemala’s remaining cloud forest.

The Sierra Madre is a mountain system that is part of the American Cordillera, a chain of mountain ranges that consists of an almost continuous sequence of ranges that form the western backbone of North America, Central America, South America and West Antarctica.

The Sierra Nevada de Santa Marta is an isolated mountain range separated from the Andes chain that runs through Colombia. Just 26 miles from the Caribbean coast, it is one of the world's highest coastal ranges, culminating in the snowcapped Cristóbal Colón, the highest peak in Colombia.
