Robert Peary based his mapping of the area on observations he made in 1892 from Navy Cliff, located north of the
Academy Glacier. From his perspective the channel allegedly connected the head of
Independence Fjord in the east with the heads of
Nordenskiöld Fjord and a parallel and misplaced "Chipp Inlet" in the west. There is a Chipp Sound that separates
Sverdrup Island from smaller Elison Island, but it is located at the other end of Nordenskiöld Fjord, beyond its mouth. In Peary's map Independence Fjord was merely a short bay and further to the east Peary had drawn the coast of hypothetical "Academy Land" slanting southeastwards with the "
East Greenland Sea" to the north. In the wake of the tragic outcome of the Denmark expedition's main team, many scholars were highly critical of Peary's cartographic errors, but
Lauge Koch, who made detailed surveys of the area in the 1920s and 30s, took a more lenient view: ==History==
