Carrizozo volcanoThe massive Carrizozo lava flow is one of Earth's longest known lava flows that were erupted in the past 10,000 years. The basalt flow is 50 m thick, 75 km long, 1-5 km wide and was mainly fed by lava tubes.
Background:The vent of the Carrizozo lava flow is a broad low basaltic shield on the floor of the Tularosa Basin, east of the Rio Grande Rift, topped by Little Black Peak, a small cinder cone with 3 nested craters and a frozen lava lake.
The flow reached a length of 75 km extending into the Tularosa Basin of south-central New Mexico. Its total volume is estimated 4.3 cubic km.
It is similar to the presently active lava flow field of Kilauea volcano on Hawai'i, and believed to have been produced by a persistent single eruption that might have lasted a few decades.
A surface exposure age of about 5200 years Before Present was obtained for the Carrizozo lava flow, the second youngest in New Mexico. An older lava flow traveled 16 km south and 11 km east from Broken Back crater.
