|Valle del Silencio, Costa Rica. 2012|
Valle del Silencio is located in Parque La Amistad, a nature reserve: “The La Amistad International Park, or in Spanish Parque Internacional La Amistad, formerly the La Amistad National Park, is aTransboundary Protected Area in Latin America, management of which is shared between Costa Rica (Caribbean La Amistad and Pacific La Amistad Conservation Areas) and Panama, following a recommendation by UNESCO after the park's inclusion in the World Heritage Site list. The park area is equally split between Costa Rica and Panama, as part of the former La Amistad Reserves of the Talamanca mountain range. It covers 401,000 ha of tropical forest and is the largest nature reserve in Central America; together with a 15 km buffer zone, it represents a major biodiversity resource at a regional (ca 20% of the region's species diversity) and global level.
This is recognized in its strategic position in the Mesoamerican Biological Corridor and its designation as a UNESCO World Heritage Site. Its cross-frontier position gives it unique potential to improve bioregional planning. The park’s buffer zone includes coffee and beef producers and indigenous subsistence farmers. As a consequence of the difficulty of the terrain, the park is relatively unexplored and the only substantial scientific explorations deep into the park have been led by the Natural History Museum London, INBio and the University of Panama in the last 6 years (2003–2008)”.

|Volcán Barva, Costa Rica. 2008|
“Barva Volcano is an andesitic volcanic shield complex in central Costa Rica, 22 km north of San José, in Heredia Province. On the eastern side of the mountain it has a lake in what formerly was the volcanic crater, called "Laguna de Barva", and in the western side it has three hills on the top which are called "Las Tres Marías". It sits on the small agricultural community of Sacramento. Barva has a dozen different eruptive spots in the summit and some parasitic cones in the flanks of the mountain. Its three principal summits visible from the Central Valley give it the common local name of Las Tres Marías (The Three Marys).
Four pyroclastic cones are constructed within the 2 x 3 km caldera at the central and northwestern part of the summit. The southwestern peak contains four cones, one of which has a crater lake. The last confirmed eruptive activity at Barva Volcano has been dated to 8,050 years ago. There were reports of eruptions in the 1760s and in 1867, but subsequent investigations at the summit did not find evidence to confirm the reports” Quoted from: http://en.wikipedia.org/wiki/Barva_Volcano (2015)
|Volcán Poás, Costa Rica. 2007-2008|
“The Poás Volcano, is an active 2,708-metre (8,885 ft) stratovolcano in central Costa Rica. It has erupted 39 times since 1828. There are two crater lakes near the summit. The northern lake is known as the Laguna Caliente ("hot lagoon") and is located at a height of 2,300 m in a crater approximately 1.7 km wide and 290–300 m deep. It is one of the world's most acidic lakes. The acidity varies after rain and changes in volcanic activity, sometimes reaching a pH of almost 0; consequently, it supports little or no aquatic life. The bottom of this lake is covered with a layer of liquid sulphur. Acid gases create acid rain and acid fog, causing damage to surrounding ecosystems and often irritation of eyes and lungs.
Lake Botos, the southern lake, fills an inactive crater, which last erupted in 7500 BC. It is cold and clear, and is surrounded by a cloud forestlocated within the Poás Volcano National Park." Quoted from: http://en.wikipedia.org/wiki/Po%C3%A1s_Volcano (2015)
