This peninsula was named during the Three-year Expedition to East Greenland owing to it being largely glaciated.

[1] True to its name, Gletscherland is largely glaciated, with many ice caps and glaciers.

[2] The peninsula has a mountainous, Alpine terrain; Mount Lugano is Gletscherland's highest point.

[2] It is bounded in the northwest by the Hisinger Glacier, in the north and northeast by the Dickson Fjord, in the southeast by the Rhedin Fjord, in the south by the Wahlenberg Glacier and to the west it is connected to the mainland.

The Röhss Fjord and the valley at its head, almost divide the peninsula in two from ENE to WSW.
