Premise: Shortcut Island is a crescent-shaped island 0.4 mi long, with three prominent indentations of the north shore, lying 0.7 mi SSE of Gamage Point and Palmer Station along the SW coast of Anvers Island. The suggestive name was given by Palmer Station personnel. The narrow, deep channel separating this island from Anvers Island is a shortcut from the station to the Biscoe Bay area by water.
Hypothesis: You can take the channel separating Anvers Island and Shortcut Island, as a water route, to get from Palmer Station to the Biscoe Bay area.
