Mount Elkins, also known as Jökelen (which means "The Glacier") is a dark, steep-sided mountain with three major peaks, the highest 2,300 meters (7,500 ft) above sea level, in the Napier Mountains of Enderby Land. Enderby Land is part of East Antarctica, and is claimed by Australia as part of the Australian Antarctic Territory. The mountain was named after Terence James Elkins, an ionospheric physicist with the Australian National Antarctic Research Expeditions at Mawson Station in 1960. [1] [2]



Some notable geographic features in the general vicinity of Mount Elkins include Cape Batterbee (92 km to the north), the Young Nunataks (7.4 km to the south), Sørtoppen Nunatak (30 km to the east), the Newman Nunataks (26 km to the west), Mount McMaster (97 km to the west), and Mount Kjerringa (57 km to the northeast). The nearest permanently inhabited place is Mawson Station, an Australian research station to the southeast. Molodyozhnaya Station, a former Soviet research station which was mothballed in 1989, is located to the southwest of Mount Elkins.

Mount Elkins is the highest peak in the Napier Mountains. It is the highest peak in Enderby Land. [3]

Geology & orogeny

Much of the East Antarctic craton was formed in the Precambrian period by a series of tectonothermal orogenic events. [4] Napier orogeny formed the cratonic nucleus approximately 4 billion years ago. [5] Mount Elkins is a classic example of Napier orogeny. Napier orogeny is characterized by high-grade metamorphism and plate tectonics. The orogenic events which resulted in the formation of the Napier Complex (including Mount Elkins) have been dated to the Archean Eon. Radiometrically dated to as old as 3.8 billion years, some of the zircons collected from the orthogneisses of the Napier Complex are among the oldest rock specimens found on Earth. [6] Billions of years of erosion and tectonic deformation have exposed the metamorphic rock core of these ancient mountains.

The oldest crustal components found to date in the Napier Complex appear to be of igneous derivation. This rock appears to have been overprinted by an ultra-high temperature metamorphic event (UHT) that occurred near the Archean-Proterozoic boundary. Using a lutetium-hafnium (Lu-Hf) method to examine garnet, orthopyroxene, sapphirine, osumilite and rutile from this UHT granulite belt, Choi et al determined an isochron age of 2.4 billion years for this metamorphic event. [6] Using SHRIMPU–Pb zircon dating methodology, Belyatsky et al determined the oldest tectonothermal event in the formation of the Napier Complex to have occurred approximately 2.8 billion years ago. [7]

Preservation of the UHT mineral assemblage in the analyzed rock suggests rapid cooling, with closure likely to have occurred for the Lu-Hf system at post-peak UHT conditions near a closure temperature of 800 °C. UHT granulites appear to have evolved in a low Lu-Hf environment, probably formed when the rocks were first extracted from a mantle profoundly depleted in lithophile elements. The source materials for the magmas that formed the Napier Complex were extremely depleted relative to the chondritic uniform reservoir (CHUR). These results also suggest significant depletion of the early Archean mantle, in agreement with the early igneous differentiation of the Earth that the latest core formation models require. [6]

Significance to mountaineers

The summit of Mount Elkins is higher than that of any mountain in Australia—including even Mount Kosciuszko (2,228 metres), which is one of the Seven Summits. Because of its remoteness it has not become a popular target for peak bagging.

Weather conditions

The Napier Mountains run northwest from Mount Elkins. To the east is a large valley formed by the Robert and Wilma Glaciers. To the northeast are the Seaton and Rippon Glaciers. All of these glaciers run into the King Edward Ice Shelf. Other notable terrain features in this area include the Beaver Glacier, located to the west of Mount King. Collectively, these terrain features significantly modify weather produced by synoptic scale systems. Dramatic changes can occur over short distances and in short time intervals. [9] [10]

Mount Elkins was first mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–37, and named at that time Jökelen (The Glacier). It was remapped by ANARE from aerial photographs taken from an ANARE aircraft in 1956. The Napier Mountains were first visited by an ANARE survey party from Mawson Station in 1960. The survey party was led by Syd Kirkby, and included Terence James Elkins.

Enderby Land is a projecting landmass of Antarctica. Its shore extends from Shinnan Glacier at about 67°55′S44°38′E to William Scoresby Bay at 67°24′S59°34′E, approximately 124 of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig Tula, and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing.

In 1979, he received the Harold Brown Award, the Air Force's highest honour for research and development, for research he conducted that contributed to the development of the AN/FPS-118 over-the-horizon backscatter (OTH-B) air defence radar system. This system, consisting of six one-megawatt transmitters and their associated horizontal linear phased array antennas, is currently the largest radar system in the world.

East Antarctic Shield Cratonic rock body which makes up most of the continent Antarctica

The East Antarctic Shield or Craton is a cratonic rock body that covers 10.2 million square kilometers or roughly 73% of the continent of Antarctica. The shield is almost entirely buried by the East Antarctic Ice Sheet that has an average thickness of 2200 meters but reaches up to 4700 meters in some locations. East Antarctica is separated from West Antarctica by the 100–300 kilometer wide Transantarctic Mountains, which span nearly 3,500 kilometers from the Weddell Sea to the Ross Sea. The East Antarctic Shield is then divided into an extensive central craton that occupies most of the continental interior and various other marginal cratons that are exposed along the coast.

Enderby Land is a region of Northeastern Antarctica which extends into the Southern Indian Ocean. The area is claimed by Australia as part of the Australian Antarctic Territory.
