# Hays Mountains

The Hays Mountains (86°S 155°W﻿ / ﻿86°S 155°W﻿ / -86; -155) are a large group of mountains and peaks of the Queen Maud Mountains of Antarctica, surmounting the divide between the lower portions of Amundsen Glacier and Scott Glacier and extending from the vicinity of Mount Thorne on the northwest to Mount Dietz on the southeast.

## Discovery and naming

The Hays Mountains were discovered by Rear Admiral Richard E. Byrd on the South Pole flight of November 28–29, 1929, and mapped in part by the Byrd Antarctic Expedition geological parties to this area in 1929 and 1934. They were named by Byrd for Will H. Hays, former head of the Motion Picture Producers and Distributors of America.

## Location

The Hays Mountains extend between the Amundsen Glacier to the west and Scott Glacier to the east. Peaks from south to north along the east side of the Amundsen Glacier include Simmonds Peak, Mount Dort, Mount Clough to the south of Cappellari Glacier and Mount Gevers to the north of that glacier, Mount Dayton, Mount Thorne, Cook Peak and the Brown Peaks. Peaks in the center of the range include Mount Goodale, Mount Armstrong, Mount Griffith and Mount Vaughan above the Vaughan Glacier. East of Mount Vaughan are the Sledging Col, Mount Pulitzer, Mount Nelson and Mount Sletten on the Taylor Ridge, which extends along the Scott Glacier to the east. Mount Astor, Mount Crockett.,the Cox Peaks, Mount Borcik, Mount Walshe and Mount Dietz are in the southeast of the range. To the south of the Hays Mountains are the Nilsen Plateau, Fram Mesa and Faulkner Escarpment.

## Western features

The feature was climbed on Nov. 16, 1987, by a USARP-Arizona State University geological party led by Edmund Stump. The name derives from granite samples collected on the wall at 100 metres (330 ft) high spacing for dating by the fission-track method.

### Mount Vaughan

85°57′S 155°50′W﻿ / ﻿85.950°S 155.833°W﻿ / -85.950; -155.833. A prominent peak, 3,140 metres (10,300 ft) high, standing 4 nautical miles (7.4 km; 4.6 mi) south-southwest of Mount Griffith on the ridge at the head of Vaughan Glacier. Named for Norman D. Vaughan, dog driver with the Byrd Antarctic Expedition geological party under Laurence Gould which explored the mountains in this vicinity in December 1929. The map resulting from the Byrd Antarctic Expedition, 1928–30, applied the name Mount Vaughan to the southern portion of Mount Goodale, but the US-ACAN has modified the original naming to apply to this larger peak which lies 15 nautical miles (28 km; 17 mi) southeastward.

### Citadel Peak

A peak of volcanic rock along the south side of Vaughan Glacier, 6 nautical miles (11 km; 6.9 mi) east of Mount Vaughan, in the Queen Maud Mountains. Mapped by USGS from surveys and U.S. Navy air photos, 1960–64. So named by New Zealand Geological Survey Antarctic Expedition 1969–70; the summit is composed of vertical rock slabs, its strange appearance being reminiscent of a castle or citadel.

The valley drains east-northeast from Mount Crockett to Scott Glacier and is partly covered by glacier and moraine. It was visited in December 1987 by a USARP-Arizona State University geological party led by Edmund Stump. The mouth of the valley is blocked by a moraine which denies easy access, hence the name.

## Eastern features

Features to the east include:

### Sledging Col

The col provides a sledging route from Scott Glacier to the head of Koerwitz Glacier and thence northward. So named by members of New Zealand Geological Survey Antarctic Expedition who used this route in 1969-70 when the west side of the lower reaches of Scott Glacier were found to be impassable.

### Dragons Lair Névé

During November 1987, the névé was the camp site of the USARP-Arizona State University geological party, which suggested the name. The name derives from the setting, surrounded by peaks, and from the appearance of Mount Pulitzer, the profile of which is remindful of a dragon.
