Mountain range in Victoria Land, Antarctica
TheAdmiralty Mountains (alternativelyAdmiralty Range ) is a large group of highmountains and individually named ranges and ridges in northeasternVictoria Land ,Antarctica . This mountain group is bounded by the sea (Ross Sea andSouthern Ocean ), and by theDennistoun Glacier ,Ebbe Glacier , andTucker Glacier .[ 1]
Discovery and naming [ edit ] The Admiralty Mountains were discovered in January 1841 by CaptainJames Clark Ross , Royal Navy, who named them for theLords Commissioners of the Admiralty under whose orders he served.[ 1]
The Admiralty Mountains lie to the east of theConcord Mountains and theVictory Mountains , separated from them by theEbbe Glacier in the north and theTucker Glacier further south, which flows into theRoss Sea . They are to the south of theAnare Mountains , separated from them by the Anare Pass and theDennistoun Glacier , which flow east to theSouthern Ocean . To their east they are bounded by the Southern Ocean,Robertson Bay , theAdare Peninsula and theRoss Sea .[ 2] [ 3] [ 4]
TheDennistoun Glacier which flows past the northeastern section of the Admiralty Mountains, separates then from theQuam Heights andHedgpeth Heights in theAnare Mountains to the north.TheRobinson Heights in the northwest Admiralty Mountains are separated from theAnare Mountains to the north by theAnare Pass .They are east of theEverett Range in the Concord Mountains.TheHomerun Range in the Admiralty Mountains is east of theMirabito Range in the Concord Mountains.Further south, the Admiralty Mountains face theCartographers Range in theVictory Mountains across the Tucker Glacier.[ 2] [ 3] [ 4]
The southern tip of the mountains joins to theHallett Peninsula to the north ofTucker Inlet on the Ross Sea.Moubray Bay is to the north of the Hallett Peninsula, and receives several glaciers that drain the southeast of the range. TheAdare Peninsula extends along the coast to the north ofMoubray Bay and enclosesRobertson Bay , which receives several glaciers that drain the central part of the mountains. To the north of this bay, glaciers drain the northeast of the mountains directly into the Southern Ocean.[ 2] [ 3] [ 4]
Mountains and peaks [ edit ] This range includes the following mountains and peaks, among many others:

Northern part of the Admiralty Mountains
The main glaciers bounding the mountains are theDennistoun Glacier to the northeast, which flows east to the Southern Ocean,Ebbe Glacier to the northwest, a tributary of theLillie Glacier , which flows west and then north toOb' Bay , and the largeTucker Glacier along the western edge, which flows southeast to theRoss Sea .
Dennistoun Glacier (71°11′S 168°0′E / 71.183°S 168.000°E /-71.183; 168.000 (Dennistoun Glacier ) Mount Black Prince ,Mount Royalist andMount Adam in the Admiralty Mountains. It flows northwest between theLyttelton Range andDunedin Range , turning east on rounding the latter range to enter the sea south ofCape Scott .[ 5] Ebbe Glacier (71°03′S 164°45′E / 71.050°S 164.750°E /-71.050; 164.750 (Ebbe Glacier ) Homerun Range andRobinson Heights , and then west-northwest betweenEverett Range andAnare Mountains into Lillie Glacier. This feature saddles withTucker Glacier , the latter draining southeast to theRoss Sea .[ 6] Tucker Glacier (72°32′S 169°15′E / 72.533°S 169.250°E /-72.533; 169.250 (Tucker Glacier ) Victoria Land , Antarctica, about 90 nautical miles (170 km; 100 mi) long, flowing southeast between the Admiralty Mountains and theVictory Mountains to theRoss Sea . There is a snow saddle at the glacier's head, just west ofHomerun Range , from which theEbbe Glacier flows northwestward.[ 7] A number of smaller glaciers drain the east of the mountains to the sea, including (from north to south)Simpson Glacier ,Pitkevitch Glacier ,Shipley Glacier ,Ommanney Glacier ,Dugdale Glacier ,Murray Glacier ,Moubray Glacier ,Burnette Glacier andIronside Glacier .[ 3] [ 4]
