The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about 185 km (115 mi) and is 24 to 48 km wide. Many peaks rise over 4,000 m (13,100 ft) and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.
Mount Cornwell is a mountain, 2,460 metres (8,070 ft) high, standing 2 miles (3 km) south of Mount Washburn in Gromshin Heights along the northeast side of Newcomer Glacier in the northern part of the Sentinel Range. It surmounts lower Vicha Glacier to the east and Newcomer Glacier to the west.
Bracken Peak is a peak, 1,240 metres (4,070 ft) high, standing in Sostra Heights south of the terminus of Newcomer Glacier and 3 miles (5 km) northeast of Mount Malone, on the east side of the Sentinel Range, Ellsworth Mountains, Antarticta. It surmounts Anchialus Glacier to the west and Vit Ice Piedmont to the east.
Mount Ojakangas is an elongated mountain rising to about 2,450 m, 2 nautical miles (3.7 km) northwest of Mount Washburn in Gromshin Heights in the north part of the Sentinel Range, Ellsworth Mountains. It surmounts Vicha Glacier to the east and Newcomer Glacier to the west.
The Miller Bluffs are a line of steep, east-facing bluffs about 15 nautical miles (28 km) long which extend west-northwest from Foros Spur at the mouth of Newcomer Glacier, along the northeast side of Gromshin Heights in northern Sentinel Range, Ellsworth Mountains in Antarctica. The north end of the feature was photographed by Lincoln Ellsworth on his trans-Antarctic flight of November 23, 1935, and the bluffs were mapped by the United States Geological Survey in 1961 from air photos obtained by U.S. Navy Squadron VX-6 in 1959. The feature was named by the Advisory Committee on Antarctic Names for the Hon. George P. Miller, former chairman of the House Science and Astronautics Committee, whose great interest in Antarctic activities was of assistance in assuring successful completion of U.S. research of that continent, 1958–72.
Matsch Ridge is a prominent ridge at an elevation of about 1,830 metres (6,000 ft), extending for 1.5 nautical miles (3 km) in a west-northwest direction from Mount Ulmer in Gromshin Heights on the east side of northern Sentinel Range in the Ellsworth Mountains, Antarctica. It is connected to Mount Wyatt Earp on the west-northwest by Skamni Saddle.
Mount Lanning is a mountain, 1,820 metres (5,970 ft) high, located at the south side of Newcomer Glacier, 5 nautical miles (9 km) southeast of Mount Warren, in the northern portion of the Sentinel Range, Ellsworth Mountains, Antarctica. It forms the north extremity of Sostra Heights, and surmounts Sabazios Glacier to the southwest and Anchialus Glacier to the southeast.
Kornicker Glacier is a glacier draining northeastwards from the cirque bounded by Mount Liptak, Mount Southwick, Mount Milton and Mount Mullen in the southern Sentinel Range of the Ellsworth Mountains in Antarctica. The glacier flows along the northwestern side of Petvar Heights and merges with the terminus of the southeast-flowing Thomas Glacier as both glaciers emerge from the range.
Aster Glacier is an Antarctic glacier descending the east slope of Craddock Massif and flowing between Elfring Peak and Willis Ridge to Thomas Glacier in the Sentinel Range, Ellsworth Mountains in Antarctica. It was named by the Advisory Committee on Antarctic Names in 2006, after Richard Aster, Professor of Geophysics and Department Head of Geosciences at Colorado State University, whose research in Antarctica includes volcanological studies at the Mount Erebus volcano observatory on Ross Island, glaciological, oceanic, and tectonic seismic source studies, seismic tomography, ice shelf studies, and the coupling of solid Earth geophysics and Antarctic ice sheet evolution.
Zhenda Glacier is the 8 km long and 4.8 km wide glacier on the east side of the main crest of northern Sentinel Range in Ellsworth Mountains, Antarctica. It is situated west of Sabazios Glacier and southeast of Skaklya Glacier. The glacier drains the northeast slopes of Mount Sharp and the east slopes of Mount Barden, flows northeastwards and together with Skaklya Glacier joins Sabazios Glacier west of Mount Lanning in Sostra Heights.
Blenika Peak is the sharp rocky peak rising to 2,496 m (8,189 ft) just east of the main crest of northern Sentinel Range in Ellsworth Mountains, Antarctica. It surmounts Zhenda Glacier to the southeast and Skaklya Glacier to the north.
Skaklya Glacier is the 3 nautical miles long and 1 nautical mile wide glacier on the east side of the main crest of northern Sentinel Range in Ellsworth Mountains, Antarctica. It is situated northwest of Zhenda Glacier and southeast of the head of Vidul Glacier. The glacier drains the south slopes of Mount Reimer and the north slopes of Blenika Peak, flows east-northeastwards and together with Zhenda Glacier joins Sabazios Glacier west of Mount Lanning in Sostra Heights.
Vidul Glacier is the 7.5 km long and 1.4 km wide glacier on the east side of the main crest of northern Sentinel Range in Ellsworth Mountains, Antarctica. It is situated northwest of Skaklya Glacier and southwest of the middle course of Newcomer Glacier. The glacier drains the north slopes of Mount Reimer and the east slopes of Mount Dawson, flows northwards and joins Newcomer Glacier west of Mount Warren in Gromshin Heights.
Anchialus Glacier is the 8.5 km long and 3.4 km wide glacier in Sostra Heights on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica. It is situated north of lower Embree Glacier, east of Sabazios Glacier, south of lower Newcomer Glacier and northwest of Vit Ice Piedmont. The glacier drains the northeast slopes of Mount Malone and the west slopes of Bracken Peak, flows northwards and joins Newcomer Glacier east of Mount Lanning.
Skamni Saddle is the 1.3 km long ice-covered saddle of elevation 1750 m in northern Sentinel Range, Ellsworth Mountains in Antarctica connecting Mount Wyatt Earp on the northwest to Matsch Ridge in Gromshin Heights on the southeast.
Gromshin Heights are the heights rising to 2731 m at Mount Ulmer on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica. They extend 35 km in north–south direction and 20 km in east–west direction. The feature is upturned U-shaped with its interior drained by the south flowing Vicha Glacier, and its northeast side marked by the extensive Miller Bluffs. The heights are bounded by Rutford Ice Stream to the east and Newcomer Glacier to the south and west, and is connected to Mount Wyatt Earp on the northwest by Skamni Saddle, and to Mount Weems on the north by Kipra Gap. Their interior is drained by Vicha and Yamen Glaciers.
Vicha Glacier is the 27 km long and 6 km wide glacier in Gromshin Heights on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica. It is situated northeast of Newcomer Glacier and southwest of Yamen Glacier. The glacier drains southwards along the east slopes of Mount Ulmer and Mount Ojakangas, then turns southeast at Mount Washburn, flows east of Mount Cornwell and Mount Warren, and southwest of Branishte Peak, and together with Newcomer Glacier joins Rutford Ice Stream south of Foros Spur.
Mursalitsa Peak is the mostly ice-covered peak on the west side of northern Sentinel Range in Ellsworth Mountains, Antarctica rising to 2334 m on the side ridge extending from Mount Sharp on the main crest of the range. It is named after Mursalitsa Ridge in the Rhodope Mountains, Bulgaria.
Arzos Peak is the sharp rocky peak on the west side of northern Sentinel Range in Ellsworth Mountains, Antarctica rising to 1893 m on the side ridge extending from a peak standing on the main crest of the range just north-northwest of Mount Dawson. Arzos is the ancient Thracian name of Sazliyka River in Southern Bulgaria.
Mount Warren is a mountain rising to 2,340 metres (7,680 ft) in Gromshin Heights, just north of the turn in Newcomer Glacier on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica. It surmounts Newcomer Glacier to the west and south, and Vicha Glacier to the northeast.
