Which formation, Łebsko Lake or Coatepeque Caldera, is part of the Słowiński National Park?
Coatepeque Caldera Caldera De Coatepeque (Nahuatl "cōātepēc", "at the snake hill") is a volcanic caldera in El Salvador in Central America. The caldera was formed during a series of minor rhyolitic explosive eruptions between about 72,000 and 57,000 years ago. Since then, basaltic cinder cones and lava flows formed near the west edge of the caldera, and six rhyodacitic lava domes have formed. The youngest dome, Cerro Pacho, formed after 8000 BC.
Sabana Formation The Sabana Formation (Spanish: "Formación Sabana" , Q1, QTs) is a geological formation of the Bogotá savanna, Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The formation consists mainly of shales with at the edges of the Bogotá savanna lignites and sandstones. The Sabana Formation dates to the Quaternary period; Middle to Late Pleistocene epoch, and has a maximum thickness of 320 m , varying greatly across the savanna. It is the uppermost formation of the lacustrine and fluvio-glacial sediments of paleolake Humboldt, that existed at the edge of the Eastern Hills until the latest Pleistocene.
