[1] Robert Peary did not explore the Frederick E. Hyde Fjord owing to thick fog at its mouth.

The inner fjord branches were mapped and named by Lauge Koch in the course of aerial surveys from the 1920s onwards.

The fjord is roughly oriented in a north–south direction and is nearly 20 km (12 mi) in length.

[3] 1,737-metre-high (5,699 ft) Mount Wistar, the highest point of the area, rises to the east of the inner section.

To the west lies the Heimdal Ice Cap.
