The transit of the Prince Christian Sound is one of the highlights of cruising in Greenland. The approximately 60-mile sound cuts between the mainland and an archipelago of islands from east to west, under the southern edge of the massive Greenland Ice Sheet, which covers 80 percent of the island. The sound is narrow, sometimes as little as 1500 feet across, and numerous glaciers reach the sea on its shores, calving icebergs into the sound. High, barren and sharply defined peaks tower on both sides. The only indications of humanity to be seen are the Ikerassasuaq weather station (using the Greenlandic name for the sound) where the ship enters, and the small village of Appilattoq, housing approximately 100 people. Animal life is more abundant, with minke, fin and blue whales seen frequently, as well as ringed and bearded seals that haul out on the floating ice. It is a breathtaking display of natural splendor in the severe, rugged vernacular of rock, ice and sea that is unique to the arctic realm.
