Separation Range
mountain range in Antarctica
Separation Range (84°5′S 174°0′E) is the northeastern branch of the Commonwealth Range in the Queen Maud Mountains, Antarctica.
The branch starts at about 84°20'S, and forms two chains of mountains separated by Hood Glacier.
The Separation Range, about 30 nautical miles (56 km; 35 mi) long, terminates to the north at the Ross Ice Shelf.
Named by the New Zealand Alpine Club Antarctic Expedition, 1959–60.
Location
The Separation range lies to the east of the northern part of the Commonwealth Range, and runs from south to north between that range and the Canyon Glacier to the east.
The Cunningham Glacier enters the Canyon Glacier just south of the southern end of the Separation Range.
The northern end adjoins the Ross Ice Shelf.
The Hood Glacier defines its western edge.
Features include Retrospect Spur, terminating in the Chevron Rocks, and Mount Cope.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Separation Range”, the useful work is to connect “mountain range in Antarctica” to the records capable of establishing context and consequence.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q7451808. Authority coordinates are -84.083, 174.000. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1959.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.
How to read it
