Lake Poco Sol (from Spanish, "Little Sunshine"), Laguna Poco Sol or Laguna Pocosol, is a volcanic lake in Costa Rica, in the Cordillera de Tilarán.[2] [3]
The lake lies at an altitude of 789 metres (2,589 ft) in a 200 metres (660 ft) wide depression.[1] The depth of the lake is about 11.5 metres (38 ft).[4]
Other volcanic features in the area include breccia, lahar deposits, lava flows and tuffs. The lake may be a landslide scar, or a crater left by a phreatic explosion. It is of probable Pleistocene age.[1][5] It is constructed within the andesitic Monteverde Formation,[5] which was erupted between 2.1 and 1 million years ago.[4]
Hot springs, mud pots and deposits of sulfur are found both at the lake and near the Río Penas Blancas.[1] The area has been investigated for harnessing geothermal energy. The geothermal activity may be the source of the name Pocosol.[4]
The active volcano Arenal lies north-northwest of Laguna Poco Sol.[5] Arenal along with Cerro Chato between Arenal and Laguna Poco Sol and Cerro Pocosol south of Laguna Poco Sol may be located along a zone of tectonic weakness that was accompanied by northeast-migrating volcanism.[4]
