Martin Peninsula
geographical object
Martin Peninsula (74°20′S 114°30′W) is a peninsula about 60 nautical miles (110 km; 69 mi) long and 20 nautical miles (37 km; 23 mi) wide that is ice-covered except for a few rock outcrops along its margins, located between Getz Ice Shelf and Dotson Ice Shelf on the coast of Marie Byrd Land, Antarctica.
The farthest point of the peninsula is Jacobsen Head.
Location
The Martin Peninsula extends north from the coast of Marie Byrd Land into the Amundsen Sea.
It defines the boundary between the Bakutis Coast to the west of Cape Herlacher, and the Walgreen Coast to the east.
Glade Bay and Sweeny Inlet are on its west side, which is the eastern limit of the Getz Ice Shelf. The Dotson Ice Shelf extends east from its eastern side.
The Kohler Range is to its south.
The 1960 Sailing Directions for Antarctica described the peninsula as follows:
Martin Peninsula projects about 70 miles northward from the mainland terminating in two smaller peninsulas formed by an inlet 15 miles long. Cape Harlacher is the northern extremity of the northwestern peninsula. From Cape Herlacher to Cape Flying Fish, about 190 miles westward, the coast is indented by a very large bay and a smaller bay, the two separated by an anvil-shaped peninsula 65 miles broad in its seaward front.

Why this record matters
The phrase “geographical object” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 14, 2026. The linked authority identifier is Q649354. Authority coordinates are -74.333, -114.500. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1960.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
