English: This photo-like image shows Carrizozo Malpais, New Mexico, USA. The lava flow varies in width from 1 kilometre along its slender neck to 5 kilometres at either end. Within its curving borders, the Carrizozo lava flow has a uniform dark colour, thanks to its basalt content. Basalt tends to flow easily, and this lava flow is described as a pahoehoe flow—advancing through lobes or toes that separate from a cooled crust. The high point on Carrizozo is Little Black Peak. This is a cinder cone—a simple type of volcano made from congealed droplets and blobs of lava that erupted from a single vent. Near the lava flow’s north-eastern end is the town of Carrizozo. Both south-east and north-west of the lava flow, the landscape appears dark, but this results not from volcanic rocks but from vegetation-lined hills.
