A field of fresh-looking, unvegetated lava flows blankets the SW flank of Osorno volcano. Prominent flow levees mark channels of individual flow lobes. Some of these lava flows were erupted from cinder cones on the SSW flank of Osorno in 1835. Explosive activity beginning on November 29, 1834 was followed by lava effusion starting January 19, 1835 that lasted until the end of February.
