Whether you view it from land, air. or sea, this massive sheet of glacial ice is all about scale. Far from the pancake-flat plane its name might suggest, the Greenland Ice Sheet's massive boulders, waterfalls and craggy, vertical cliffs make it one of the most dramatically beautiful places on the globe. It's also brutally cold, holding the top spot for the coldest place in the Western Hemisphere with a record low of -87 F recorded at a British research station.
