Hey, I'm Logan. I do a lot of maintenance/licensing work here on Commons, including reviewing files from external sources (such as Flickr and Panoramio) and renaming files that need to be renamed. I also transfer many files from local wikis, such as the English Wikipedia, so that they can be on Commons for everyone to use. :)
Feel free to drop me a note on my talk page if you have any questions and/or concerns. I have a more substantial user page over at the English Wikipedia, so you can find more details about my editing there.
Hverfjall, located in northern Iceland's Mývatn region, is a rare example of a tuff ring volcano. The diameter of its crater spans approx. 1 km. A glimpse of Lake Mývatn can be spotted in the background.
