Laguna del Maule (volcano) about fourteen shield volcanoes and stratovolcanoes that have been degraded by glaciation. The Laguna del Maule volcanic field covers a surface area of and contains cones, lava domes, lava flows, and shield volcanoes. There are 130 volcanic vents at Laguna del Maule. The lake is surrounded by 36 silicic coulees and lava domes. Over of the field is covered by these rocks, and volcanic ash and pumice produced by the eruptions has been found in Argentina. Presently some summits around Laguna del Maule reach altitudes of . The volcanic field lies at an average height of . Among the various
Laguna del Maule (volcano) of mountains farther west, leading to a lack of glaciation at the numerous summits exceeding in altitude around the lake. Most of the lake water comes from snowmelt; for much of the year the landscape around the lake is covered with snow. The area of Laguna del Maule was glaciated during the last ice age, with a maximum occurring between 25,600±1,200 and 23,300±600 years ago. Probably due to changes in the position of the Westerlies, after 23,000 years ago the glaciers retreated above Laguna del Maule. The glaciation has left moraines and terraces in the area, with undulating hills lying
