Cape Bathurst has changed its position to the north by almost three degrees of latitude and to the west by several hundred miles; Hobson determines that the Cape has become an island. Now the party's only hope is the onset of winter, so they might travel across the ice, to reach the mainland Russian America (Alaska). When a mild (by Arctic standards) winter sets in and the island is locked by the ice directly north of the Bering Strait; but the ice is not sufficiently frozen enough for safe passage across the ice. The islands colonists wait for the spring thaw and hope that island will move south with the Bering current and that the boat they've built will be able to take them to safety.
