What topic do I list Greenland under - not quite Europe, not Quite North America.....
Wilderness and Ecology is a good header for this link. A correspondent for NPR traveled to Greenland and upon his return NPR put up a section devoted to his photos and info gathered. He has topics from lemming scat to polar bear tracks, from Inuit to Viking, from ice core samples to ultraviolet light studies. The photos are gorgeous.
