The Thomas Hills (84°21′S 65°12′W) are a linear group of hills, 17 nautical miles (31 km; 20 mi) long, between Foundation Ice Stream and MacNamara Glacier at the north end of the Patuxent Range in the Pensacola Mountains, Antarctica.

Exploration and name

The Thomas Hills were mapped by the United States Geological Survey (USGS) from surveys and from United States Navy air photos, 1956–66.

They were named by the United States Advisory Committee on Antarctic Names (US-ACAN) at the suggestion of Captain Finn Ronne, United States Navy Reserve, leader at Ellsworth Station, 1957.

Charles S. Thomas was United States Secretary of the Navy, 1954–57, during the first few years of United States Navy Operation Deep Freeze.

Location

The Thomas Hills run in a northeast direction between the Foundation Ice Stream and the MacNamara Glacier. They parallel the Anderson Hills on the south side of the MacNamara Glacier.

Features, from west to east, include Mount Yarbrough, Nance Ridge, Martin Peak and Mount Warnke.

Editorial analysis

Why this record matters

“Thomas Hills (Antarctica)” is worth following because a concise public description often conceals a longer documentary argument. Here, Thomas, Hills and Antarctica provides the most credible route into that argument.

Evidence profile

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 Aug 16, 2026. The linked authority identifier is Q7790693. VIAF identifies the subject as 239172276. Authority coordinates are -84.350, -65.200. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1956, 1957, 1954 and 1965.

Critical limits

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.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
