They are of volcanic origin, consisting of low scattered mountains and nunataks that protrude through the West Antarctic Ice Sheet.

The Hudson Mountains are bounded on the north by Cosgrove Ice Shelf and on the south by Pine Island Glacier.

The Hudson Mountains rise in western Ellsworth Land[3] of West Antarctica[4] and were discovered in 1940 by the United States Antarctic Service Expedition.

[5] The mountains lie at some distance from the Amundsen Sea's Walgreen Coast,[6] facing Pine Island Bay.

[23] Glaciers have deposited granite boulders and erratic blocks on the Hudson Mountains,[25] and left glacial striations on the pillow lavas of Mount Moses.

[30] Seismic tomography has found evidence of low velocity anomalies under the Hudson Mountains, which may reflect the presence of the Marie Byrd Land mantle plume.

[37] The magmas erupted by the volcanoes may have originated in a mantle that had been influenced by subduction,[38] and underwent fractionation of olivine as they ascended.

[14] An automated weather station was installed on Evans Knoll in 2011 and records air temperatures and wind speeds.

[5] Ice cover was thicker on the Hudson Mountains during the last glacial maximum, perhaps by about 150 metres (490 ft).

[45] Retreat commenced about 14,000[46]-10,000 years ago;[47] however, glaciers were still thicker than today during the early Holocene and deposited rocks on the Hudson Mountains.

A mainly snow-covered knoll on the coast at the north side of the terminus of Pine Island Glacier.

Named by US-ACAN for Donald J. Evans who studied very-lowfrequency emissions from the upper atmosphere at Byrd Station,1960-61.

A nunatak located 10 nautical miles (19 km; 12 mi) east-southeast of Mount Manthe, at the southeast end of the Hudson Mountains.

A nunatak standing 10 nautical miles (19 km; 12 mi) east of Mount Manthe in the southeast part of the Hudson Mountains.

Isolated nunatak about 20 nautical miles (37 km; 23 mi) east-southeast of Mount Manthe, at the southeast margin of the Hudson Mountains.

Named by US-ACAN for Walter Koehler, United States Army Aviation Detachment, helicopter pilot for the Ellsworth Land Survey, 1968-69.

A rock outcropping along the coastal slope at the west margin of the Hudson Mountains, located 15 nautical miles (28 km; 17 mi) northwest of Mount Moses.

A nunatak located 5 nautical miles (9.3 km; 5.8 mi) west-southwest of Mount Moses, in the central part of the Hudson Mountains.

The highest 750 metres (2,460 ft) high and most prominent of the Hudson Mountains, located near the center of the group, about 14 nautical miles (26 km; 16 mi) north-northeast of Mount Manthe.

Named by US-ACAN for Ronald A. Hodgson, United States Navy, builder with the Byrd Station party, 1966.

Named by US-ACAN for Major Edward Rebholz, operations officer of the United States Army Aviation Detachment which supported the Ellsworth Land Survey, 1968-69.

A distinctive rock cliff which faces northward toward Cosgrove Ice Shelf, standing 5 nautical miles (9.3 km; 5.8 mi) northeast of Mount Nickens at the north end of the Hudson Mountains.

An isolated nunatak which lies about 8 nautical miles (15 km; 9.2 mi) southeast of the head of Cosgrove Ice Shelf and 17 nautical miles (31 km; 20 mi) east-northeast of Pryor Cliff, at the extreme north end of the Hudson Mountains.

Named by US-ACAN for Richard E. Kenfield, USGS topographic engineer working from Byrd Station in the 1963-64 season.
