Isfjord

Some 50km/30mi north of the wide Bellsund is the Isfjord (100km/60mi long including its branches), which cuts more than halfway across the island of Spitzbergen. While the north side is partly covered by glaciers, the south side falls down to the fjord in steep-sided tabular hills. In this fjord are the two principal settlements on the island, Longyearbyen on Advent Bay and Barentsburg on the Grønfjord.
