Aliso volcano is a newly discovered active stratovolcano complex at the eastern foot of the Ecuadorian Andes, east of Antisana volcano and SW of the town of Baeza. It contains andesitic lava flows, lava domes and pyroclastic flow deposits. Aliso volcano is dormant and has been last active about 2000 years ago.

Background
from Smithsonian / GVP Aliso volcano information:The largely unexplored complex contains a curved summit ridge on the west with older andesitic lava flows and tundra-like vegetation, and rhyolitic and dacitic lava domes in a wet cloud-forest environment on the lower eastern flanks.
The Pumayacu center on the SE flank contains several lava domes along a NNE axis parallel to the Andean Thrust Fault System (TFZ). Morphologically young andesitic lava flows occur along the flat-topped ridge above Baeza town. The Pumayacu center erupted pyroclastic-flow deposits of late Pleistocene and Holocene age. One pyroclastic-flow deposit was dated at about 4400 years Before Present, and a pumice lapilli layer overlies a ceramic-rich cultural horizon thought to be about 2000 years old
