A goal of Pan Reas on their Someday list with a status of Done.
I explored the Lofthellir Ice Cave in Myvatn, Iceland. It took some effort to slide into/up some parts, using a rope to hoist myself. There are lovely icicles all around, and a great part at the end when the guide turned off all the torches and we turned off our headlights and sat in lovely silence until he used the icicles to make gentle music.
