Cinder cones above the clouds
It's easy to forget we work on top of a volcano. Mauna Kea isn't active but is classified as dormant - certainly not an extinct volcano. It last erupted around 4,500 years ago but it will likely erupt again. No one knows when. The cinder cones that litter the summit area and the rest of the mountain bear testimony to a time not long ago when the mountain spat fire.
