Volcán Lomas Blancas is a small shield-like stratovolcano of late-Pleistocene to Holocene age (Moreno and Naranjo, 1991) located about 15 km SE of Nevado de Longaví volcano. A 2.3-km-wide caldera, possibly formed by edifice collapse, is open to the SE. Basaltic-andesite aa lava flows extend 7 km from the collapse scarp. The basaltic central cone rises about 500 m to an elevation of 2268 m. Much of the volcano is covered by pumice deposits that probably originated from Nevado de Longaví.
