The arctic wolf is the rarest land mammal in Greenland. Most of the time during our expeditions, we do not encounter them, but when we do, they may approach closely, hang out at our camp, and steal anything they can carry away. In summer, they are easily visible from miles away on the treeless, green and brown tundra. In winter, they are harder to see, but they often find us, before we find them. They are not dangerous but, as with any wild animal, complacency is not recommended. At this high latitude, many, especially young wolves, have undoubtedly never encountered people and may approach boldly to within 3 meters. Others do not get closer then 200-300 meters and display great weariness. Because of their rarity, anytime we see them is an enormous privilege. Living with them in full view of their den site, watching the alpha female nursing her pups in the midnight sun is, in Greenland at least, quite possibly, a once-in-a-lifetime experience.
