I've long been fascinated by the abstract patterns formed by frozen water.  The color and stratifications have infinite variety, as much created by geography as by climate.  

Two hours outside of Reykjavik is the Eyjafjallajokull massif, and just a bit further east is the Solheimajokull glacier, extending down from Myrdalsjokull, Iceland's fourth largest glacier.  It appears at first to be easily manageable, but on closer scrutiny, has crevasses and clefts that can be treacherous for the unwary or unsure of foot.  

These particular glacial formations have additional patterns created by soot encrustations of fallout from the massive eruption of the Eyjafjallajokull volcano, in April, 2010.
