Archive - Hverfjall Crater, Iceland
August 05, 2018
Each Sunday we present a notable item from our archives. This EPOD was originally published August 4, 2012.
The stark photo above was taken from the rim of Hverfjall (Crater Mountain) in Iceland. Hverfjall is more than a half a mile wide (1000 m) and 450 feet (140 m) deep. Only a portion of the nearly circular tuff cone is visible in this photo. Everything up here is gray, so much so that it’s difficult to tell this is a color photo. The trail to the rim was a nearly vertical hike through loose, rocky terrain consisting mainly of tephra. From the top, I could see steam plumes from the Namafjall geothermal area in the distance (visible at the left). This area is part of a fissure swarm from the Krafla volcano to the north and was covered by a shallow lake about 2500 years ago. Blasting through the water the phreatomagmatic eruption threw tephra and tuff over a wide area where it pretty much remains today. The hike is a popular tourist destination but the day I did it, I was the only person around. Photo taken on September 9, 2011.
