Few Glaciers in Iceland tend to melt beneath its tongue, freeze real hard & form caves within. To be under one can be a bit risky if it caves in, which happens at times, but is absoluletly surreal inside. It's cold, damp, you hear the water droplets dripping around & a mystical blue aura surrounds you, as the sunlight penetrates the thick & the not so thick ice sheath above!
A place where the brave can meditate! A place where there is indeed light at the end of the tunnel! :-)
