Aboveground Lava Tube

Summary Author: John Kupersmith  

Craters of the Moon National Monument, in southern Idaho, is a volcanic area containing several lava tubes. These are structures that were created by pahoehoe (smooth) lava flowing in a channel. The outer shell cooled, leaving a hollow tube. This particular tube, located off the Wilderness Trail, is partly aboveground. Fractures caused by cooling are quite obvious. Photo taken on September 29, 2020.
