The McCuddin Mountains are a small cluster of mountains in Antarctica consisting mainly of two large mountains, Mount Flint and Mount Petras, along with several scattered peaks and nunataks . Located in Marie Byrd Land , 64 km (40 mi) east of the Ames Range , with Wallace Rock as its southeast extremity.
13-529: The mountains were discovered and photographed from the air in a flight from West Base of the U.S. Antarctic Service on Dec. 14, 1940. They were mapped by U.S. Geological Survey (USGS) from surveys and U.S. Navy air photos, 1959-65. Named by Advisory Committee on Antarctic Names (US-ACAN) for Rear Admiral Leo B. McCuddin , U.S. Navy (USN), Commander of the U.S. Naval Support Force , Antarctica, 1972. Mount Flint ( 75°44′S 129°06′W / 75.733°S 129.100°W / -75.733; -129.100 )
26-571: A 4,000 m peak is that it has a prominence of 30 metres (98 ft) or more; it is a mountain summit if it has a prominence of at least 300 metres (980 ft). Otherwise, it is a subpeak. In many parts of the Western United States , the term summit can also be used for the highest point along a road, highway, or railroad, more commonly referred to as a pass . For example, the highest point along Interstate 80 in California
39-450: A line, trail, or route. The highest summit in the world is Mount Everest with a height of 8,848.86 m (29,031.7 ft) above sea level . The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary . They reached the mountain's peak in 1953. Whether a highest point is classified as a summit, a sub peak or a separate mountain is subjective. The International Climbing and Mountaineering Federation 's definition of
52-417: A mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation , but not reaching a certain cutoff value for the quantities, are often considered subsummits (or subpeaks ) of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along
65-613: Is a high, prominent, ridge-shaped mountain, 2,865 metres (9,400 ft), standing 16 km (10 mi) southeast of Mount Flint. It was discovered by the US Antarctic Service (USAS) on a flight from West Base on December 15, 1940, and named for Theodore A. Petras, master technical sergeant, USMC , pilot of the airplane, a Beechcraft 5PCLB, Model D-17-A, SN357 REG NC20778 on this flight with Dr. Siple . Navarrette Peak ( 75°55′S 128°45′W / 75.917°S 128.750°W / -75.917; -128.750 )
78-416: Is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme , apex , peak ( mountain peak ), and zenith are synonymous . The term top ( mountain top ) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of
91-699: Is a prominent rounded and mainly snow-covered mountain, 2,695 metres (8,842 ft), standing 16 km (10 mi) NW of Mount Petras. The feature was observed from aircraft of the U.S. Antarctic Service (USAS) in Flight G, Dec. 15, 1940, and was briefly referred to as "Mount Gray". Asher Peak is a peak in the south west portion of the mountain. It was mapped in detail by U.S. Geological Survey (USGS), 1959-65. Named by US-ACAN for Robert B. Flint, Jr., U.S. Antarctic Research Program (USARP) scientist on high latitude geophysical and geomagnetic phenomena. Flint wintered over at Byrd Station , 1964, Plateau Station where he
104-732: Is a rock peak marking the southwest extremity of the Mount Petras massif, in the McCuddin Mountains of Marie Byrd Land . Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1959–69. Named by Advisory Committee on Antarctic Names (US-ACAN) for Captain Claude Navarrette , U.S. Navy, Deputy Commander and Chief of Staff to the Commander, U.S. Naval Support Force , Antarctica, during Operation Deep Freeze 1972. He also served on
117-734: Is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica . The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature
130-904: The Antarctic Treaty System . The research and staff support for the ACAN is provided by the United States Geological Survey . ACAN has a published policy on naming, based on priority of application, appropriateness, and the extent to which usage has become established. The United States Secretary of the Interior is in charge of formally appointing the members of the committee.

Schwob Peak ( 75°53′S 128°39′W / 75.883°S 128.650°W / -75.883; -128.650 ) is a peak standing 2,715 metres (8,907 ft) located 2.4 km (1.5 mi) south of Mount Petras.

#1732790510969156-460: Was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by

Gillick, U.S. Navy Reserve , helicopter pilot who flew close support for United States Antarctic Research Program (USARP) scientists during Operation Deep Freeze 1970 and 1971.
