Administratively it is part of the Northeast Greenland National Park zone.

It was named by Swedish Arctic explorer A.G. Nathorst on his 1899 expedition after Scottish geologist Charles Lyell (1797–1875).

At the western end flows the Wahlenberg Glacier, beyond which lies Gletscherland.

The peninsula is attached to the mainland in the southwest, on the southern side of the glacier.

[2] The Argand Glacier, the Polhem Valley and the Berzelius Bjerg massif, are some of the outstanding features of the peninsula.
